Made in Ukraine. Resources from wastes

Today, for most industries, the important task is to find resources for various industrial fields. At the VP Kukhar Institute of Bioorganic Chemistry and Petrochemistry of the NAS of Ukraine is studying the energy and resource potential that have wastes containing organic matter.


Biodiesel based on biodegradable raw materials

The method of homogeneous-catalytic ethanol ethanol transesterification of vegetable oils (completely biodegradable and produced in Ukraine raw materials) is proposed and the original technology of obtaining ethyl esters of fatty acids can be used, which can be used as an alternative motor fuel of biological origin. The advantage of this technology over the classic is the replacement of highly toxic methyl alcohol derived from natural gas with environmentally-friendly bioethanol, which makes the raw material base of this process completely biodegradable, and the synthesized ethanol biodiesel fuel more environmentally friendly. biodiesel fuel has shown unique energy-ecological characteristics: in blends with diesel oil of oil origin in concentrations of 20-80 % synthesized product is dominated by high quality (Euro) grade II oil (slightly up to 1%) higher engine maximum power, 2-7% higher maximum torque, 1-3% higher engine efficiency, characterized by by 1-5% lower values ​​of emissions into the atmosphere of carbon dioxide, smaller by 1.3-1.5 times values ​​of emissions of nitrogen oxides, 1.2-1.3 times by carbon oxides, by 1.9-3.3 times - incomplete combustion products, 1.1-2 times lower smokiness, with the last four characteristics of tailoring are blasted over the entire concentration range, including pure biodiesel, inclusive.
The bio-ecological engine synthesized product outperforms methanol-based fuels and is the only biodiesel fuel known to date as a result of which internal combustion engines are burned in cylinders. Nitrogen oxides do not increase, but, on the contrary, significantly decrease, which makes it environmentally acceptable.
Today, analogues of biodiesel fuel ethanol oil transesterification, as well as its technology Ukraine does not exist.

Wastewater sludge dewatering technology using elements of GeoTube technology

The technology of deep dewatering of sewage sludge (on the example of Bortnaya BSA aeration station) was developed with the help of container technology (elements of GeoTube technology) and the possibilities of using such technology in real conditions were explored. Its high efficiency in the dehydration of aerobically-stabilized sediments and purification of backwash water is shown. The technological scheme of the processes is developed, the implementation of which will solve the extremely acute environmental problem of Kiev: reduce the load on the sludge sites due to a more complete dewatering of the silt and eliminate the potential threat of breakage of the barrier dams and catastrophic pollution of the Dnieper; significantly improve the quality of the sewage that returns from the sludge sites to the "head" of the biological treatment process.

A pilot laboratory facility has been created to work out the process of dewatering various naturally occurring sediments in the “sediment outside the container> water through the geotextile material inside the container with its constant drainage”. At this pilot plant, a series of sediment dewatering experiments were conducted in the aerobic-stabilized sediment (CACO) shop of the Bortnitsa Aeration Station. The characteristics of the water obtained in the filtration processes are given in the tables. Regeneration modes for filtering geotechnical fabric have been worked out and the performance of the pilot plant has been determined.

Technology of purification of industrial and sewage for small cities and settlements by anaerobic digestion in psychrophilic conditions has been developed. The technology is based on the concept of modernization of existing wastewater treatment plants, which provides:

  • replacement of primary sedimentation tanks with anaerobic psychrophilic EGSB reactors (expanded granular sludge bed) with expanded granule layer;
  • application for aerobic purification of facilities having the characteristics of light-load air filters and aeration tanks;
  • ensuring the permanent removal of partially degraded organic matter from the EGSB reactor to the next purification step;
  • ensuring the discharge of excess sludge from the aerobic purification step into the EGSB reactor;
  • ensuring purification of waste water from nitrogen-containing compounds (denitrification);
  • the use of anaerobic reactor (ABR) for wastewater denitrification;
  • use of highly loaded sludge sites;
  • using jet aeration using submerged sludge pumps for deeper saturation of sludge with oxygen directly in the aerator.

Purification of municipal effluents under psychrophilic conditions is carried out by anaerobic microorganisms that conduct the biodegradation of water-soluble organic compounds (poliants). The use of such agrobiocenoses has allowed for sewage treatment and dozens of sludges and excess sludge to be reduced.

The implementation of this technology provides the following:

  • implementation of existing facilities of the psychrophilic EGSB reactor will unload and improve the operation of aeration tanks at low costs for reconstruction and modernization
  • creation of low-cost CBS projects for new construction with specific energy costs (no more than 0.2-0.5 kWh / m3 of wastewater);
  • reducing the amount of silt on dry matter, which is characterized by good water-repellent properties, high ash content and stability, and, consequently, a significant reduction of the area of sludge sites in comparison with existing technologies 4-5 times;
  • possibility of biogas production for own needs of CBS (heating, hot water supply); - stability of the system to changes in hydraulic modes and no need for facilities for averaging of runoff;
  • decentralization of sewage treatment in settlements - possibility of automation of technological process of sewage treatment - remote control capability.

The technology was introduced at Kanev sewage treatment plants, resulting in an increase in sewage treatment depth and a decrease in sediment (sludge) by about 50 times, which reduced the area of sludge sites from 2.0 to 0.12 hectares.
The widespread introduction of this technology at minimal financial and resource costs can significantly improve the environmental situation in Ukraine.

Laboratory equipment has been created to study the process of explosive autohydrolysis of plant biomass over a wide range of temperatures and pressures. Studies have shown that all starting materials of vegetable origin, which were processed in the process of explosive autohydrolysis, underwent a breakdown of its structure, and the mixture of end products had a mushy appearance. Further processing of the resulting mixture allowed it to be divided into the following components: microcrystalline cellulose, hemicellulose, water-soluble sugars and lignin. It has been established that pretreatment of vine-like millet under conditions of explosive autohydrolysis promotes intensification of the fermentation process (bacterium Clostridia acetobytylicum) in the direction of obtaining biobutanol, which, in our opinion, is caused by the dissolving of plant material, that is, by the disclosure its structure, which in turn facilitates the access of bacteria to nutrients. Fermentation of grapefruit millet treated with autohydrolysis yielded butanol yield of 3.0 g / l. At the same time, world achievements are at 2.0-2.5 g / l.

A number of functional eco-friendly surfactants, biofuels and lubricants have been developed on the basis of chicken fat. Good lubricating properties provide process fluids, with their use, high tribotechnical characteristics, good cleaning and cooling properties, which allows to recommend them not only as biofuels, but also functional additions to technological systems for various spheres with high toxicological-hygienic and ecological requirements. Lithium plastic grease on the basis of chicken fat, as a thickener, in terms of penetration, dropping temperature, mechanical stability and other requirements of the specifications is not inferior to the commercial lubricant Litol-24 (GOST 21150), complex calcium - grease Uniol-2M / 1 (GOST TU 38.5901243), hydrated calcium - grease "Solidol fat" (GOST 1033). At the same time, biodegradability of new oils by 10-20% is dominated by existing product analogues, which opens the way to cheaper and further greening of the technology of production and use of lubricants.

Compositions of micro-emulsion types of lubricants and coolants, differing in thermodynamic, sedimentation and thermal resistance, as well as gear oils and anti-scratch oils for three-destructive tool-destroying tools, have been developed using sulfur-containing ethyl esters of FFA and oils. , antioxidant and protective characteristics are not inferior, and organoleptic, toxicological and ecological characteristics (biodegradability within 21 days makes 93%) are significantly superior to industrial ones. Analogs. Developed oils, plastic oils and lubricants meet the world's best analogues. Their practical importance is confirmed by patents and applications for inventions.

Surfactants based on oils and phosphatides

Traditional lubricants are biodegradable products (10-30%). Their production is accompanied by emissions of more than 13 tonnes of CO2 into the atmosphere, and in the process of use about 36% of them are deposited in the form of toxic oil mist on soils and roads. The Department of South Africa IBONH NAS of Ukraine has proposed a comprehensive solution to the problem of
transformation of by-products from oil purification with obtaining environmentally friendly
multifunctional surfactants to lubricants.

 


Motor oil 10M-BIO for duple engines

The urgency of the problem. Today in all economically developed countries of Western Europe, the USA and Canada in the parks, urban and suburban areas of recreation, agriculture, forestry and water management it is forbidden to use of lubricants of oil origin, which are due to high stability and slow schedule for a long time are held on the surface of the earth and reservoirs. Instead, organic oils are widely used on the basis of vegetable oils, which are naturally and completely absorbed by microorganisms in nature.
The marketing and forecasting of biofuels production and use are conducted at the UNHCR of NAS of Ukraine. lubricants from reproduced vegetable raw materials. On the basis of rapeseed and sunflower oils, with the addition of detergent-dispersive additives, a similar foreign 10M-BIO oil was developed, which, according to the results of tests at enterprises in Kyiv, meets the world standards for two-stroke oils of gasoline engines. 10m-Bio engine oil is characterized by improved viscosity-temperature properties (according to TU 23.2-30084964-005-2003 - kinematic viscosity at 100 оС - 8, 0-11,0 mm2 / s (cSt); flash point - over 200 ° C) and in baseline moham leading manufacturers of compact equipment Husquarna, Dolmar, Stihl. It provides high engine cleanliness, good starting qualities when cold and hot start, perfect condition of piston rings and protection against wear and corrosion, high environmental friendliness (SES-L-33-T-82 biodegradability is more than 95%). 10m-Bio engine oil is intended for use in two-stroke, water or air-cooled engines by pre-mixing the oil with fuel or separating them automatically into the combustion chamber. Recommended for scooters, mopeds, motorcycles, motor boats, chains dust, snowmobiles, snowblowers, lawn mowers, hedge trimmers, etc. Due to its high anti-corrosion properties, the oil can also be used for internal preservation of two-stroke engines for storage, transportation and seasonal decommissioning. 10m-Bio is mixed with various types of fuels and is recommended for use in two-stroke gasoline engines, taking into account the proposals of the manufacturer of the technical means, preferably at a ratio of “oil:gasoline = 1: 50 ".

The cost of 10m-Bio oil, due to the use of its own natural renewable raw materials, is 2-4 times lower than the imported type of imported oil purchased in Sweden or Germany. Engine oil 10m-Bio can be delivered in Euros with a capacity of 216.5 liters and in plastic cans of 5 liters and 1 liter. Potential manufacturer - Ivano-Frankivsk company Barva.

Sensor material based on conductive and industrial polymers and a system for recording its sensory response

The material is a transparent composite polymer film on the basis of a dielectric industrial polymer (polyethylene terephthalate, polyamide, polycarbonate, polyvinylidene fluoride, etc.), in the surface layer (1-2 μm) which is distributed by polymerization sensory polymer polyaniline (LADY). Depending on the chemical status of polyaniline (emeraldine base or salt), the material may interact with substances with acidic properties (hydrochloric, acetic, formic acids, etc.), or with basic properties (ammonia, alkali solutions, etc.). As a result of such interactions, PANI changes color, optical density, and electrical conductivity (Fig. 1), allowing it to use its composites in the corresponding sensor devices. The composite dielectric matrix provides high strength and stability for the sensor material.


Fig. 1 Fig. 2

In order to record the sensory response of the developed materials in the gas phase, a sensory system was developed in the gas phase after changing their optical density (Fig. 2). When using PANI in the basic form, the system gives a linear response to compounds with acidic properties (eg, formic acid 150-500 ppm), in salt - to compounds with basic properties (eg, ammonia 4-600 ppm). The developed material and system can be used in chemical industries using ammonia or different acids to look for the leakage of these substances into the environment.
