Catalysts for the disposal of toxic combustion products (СО, NOx, CnHm) of natural gas
Catalysts are designed for purification of gas-air mixtures, which are used to heat greenhouses and fertilize indoor plants with carbon dioxide, formed during the combustion of natural gas in flares of gas burners, gas boilers, picket furnaces and more.
The catalytic filter unit performs high-efficiency purification of hot air from toxic components (carbon monoxide, nitrogen oxides, hydrocarbons), i.e. CO2 and H2O can be sent to greenhouses for plant nutrition.
Catalysts of three-component purification of exhaust gases of internal combustion engines of cars (catalytic converters)
Patent of Ukraine № 79027, № 102710
The developed technology of catalysts allows to reduce the content of platinum metals in 2-3 times in comparison with analogues without decreasing of purification efficiency and service life of neutralizers. Catalysts are characterized by low temperatures to achieve high degrees of purification from toxic components (170-300 °C) and resistance to sulphur compounds..
Soot filters with a catalytic covering for clearing of emissions of diesel engines from solid microparticles
The filters ensure the combustion of soot microparticles in a continuous mode at operating temperatures of gas emissions..
Tests on motor installations («Malyshev Factory» (Kharkiv), High Pressure Combustion Laboratory of the Pennsylvania State University (USA), «Melitopol Motor Plant» (Melitopol)) showed that the efficiency of the developed systems of catalytic neutralization of exhaust gases is not inferior to foreign analogues.
Catalyst for the selective reduction of nitrogen oxides in oxygen-containing exhaust gases
Patent of Ukraine № 85669
It is designed to neutralize nitrogen oxides (NO, NO2) in the exhaust gases of automobile engines operating in the mode of “depleted” fuel mixture, diesel-electric units, etc.
In comparison with analogues, the block catalyst is characterized by greater availability of active components, higher productivity, lower gas-dynamic resistance and reduced content of precious metals.
Catalysts for the selective reduction of nitrogen oxides with ammonia
Patent of Ukraine № 19317, № 32552
Catalysts are designed for purification of exhaust gases of industrial heating units (CHP, TPS), gas turbines and other units from nitrogen oxides in the presence of oxygen.
Together with “Catalyst” (Kamianske) granular and block catalysts for the selective reduction of nitrogen oxides with ammonia in the exhaust gases of nitric acid production developed:
STRUCTURED CATHALISTS FOR COMBINED REFORMING OF C1-C4-ALKANES WITH THE PREPARATION OF HYDROGEN AND SYNTHESIS GAS
Patent of Ukraine № 108461
They are designed for the processes of steam, carbon dioxide conversion of methane to produce hydrogen and synthesis gas (СО+Н2) for the subsequent synthesis of ammonia, methanol, diethyl ethers, Fischer-Tropsch synthesis.
In comparison with analogues, the catalyst is cheaper to operate, has a lower content of active ingredients, it is characterized by high productivity, resistance to carbon and sulphur-containing compounds, low gas-dynamic resistance, a wide range of operating temperatures (500-1000 °C), and has no precious metals. In the process of steam conversion of methane the catalyst predominate foreign analogues (DIAP-16, Haldor Topsoe R-67-7H).
CATALYSTS OF FLAMELESS COMBUSTION OF NATURAL GAS AND GAS CONDENSATE IN HEAT GENERATORS
Patent of Ukraine № 77552, № 103813
They are designed for combustion of gaseous hydrocarbon fuels (С1-С4 alkanes) in portable and industrial catalytic heat generators, as well as for use in the systems of catalytic purification of exhaust gases from hydrocarbon impurities (in chemical, petrochemical and metallurgical industries).
CATALYSTS FOR LOW TEMPERATURE PURIFICATION OF AIR AND GAS EMISSIONS FROM OZONE
During the gas passing through the catalyst bed there is a stable decomposition of ozone to oxygen at room temperature.
The catalyst provides purification from ozone of:
Industrial use (Dnipro water supply station of Kyiv; “Ukrplastyk”, etc.) has shown that the developed catalysts provide stable ozone treatment.
CRUST-TYPE STRUCTURED CATALYSTS FOR PURIFICATION OF GAS EMISSIONS FROM CARBON MONOXIDE AND ORGANIC COMPOUNDS OF DIFFERENT CLASSES
Patent of Ukraine № 56859
Catalysts are designed to purify gaseous emissions from highly toxic organic compounds of various classes, primarily aromatics (benzene and its homologues), including polycyclic hydrocarbons (naphthalene, anthracene, benzopyrene), carbon monoxide and other toxic compounds.
Catalysts have passed industrial tests and are used at the Kyiv plant of medicines (purification from a mix of organic solvents), “Poltava diamond plant” (purification from phenol, formaldehyde, acetone, carbon monoxide) and other enterprises.
In terms of their performance characteristics, the developed catalysts surpass those known in the CIS countries.
CRUST-TYPE STRUCTURED CATALYSTS FOR SELECTIVE REDUCTION OF NITROGEN OXIDES BY AMMONIA
Patent of Ukraine № 145558
The ACZ-CT catalyst is designed for purification of exhaust gases in productions, the technology of which is accompanied by emissions of nitrogen oxides into the atmosphere.
The technological process of manufacturing of the developed ACZ-CT catalyst in the conditions of “Catalyst” (Kamianske) has been worked out. Tests on a pilot plant on the current unit of production of non-concentrated nitric acid of the holding “Ostchem” showed that the developed catalyst provides a reduction of residual nitrogen oxides in the purified gas to the 0.001-0.002%vol. and almost complete absence of ammonia.
The ratio of NH3/NO = 1,2 is optimal to ensure the proper level of purification from nitrogen oxides, which is lower compared to the known industrial catalyst, which reduces the amount of ammonia for purification of exhaust gases in the nitric acid industry.
