The international scientific community in the recent years deserves great attention to the problem of greenhouse gases emissions into the atmosphere. Particular importance was given to the development of CO 2 capture and storage strategies. This work investigates the possibility to use carbonized rice husk as a low cost starting materials for the production of СО 2 sorbents. The performances toward CO 2 capture of materials based on rice husk were carried out in a static microreactor showed high efficiency up to 60% with respect to the previously studied carbon-based sorbents.

The determination of content hydrocarbon of diesel fuels and individual hydrocarbons in oil-polluted soil before and after bioremediation by oil-oxidational microorganisms was carried out by method of chromato-mass-spectrometry. It has been shown that changes in composition hydrocarbons of diesel fuels and individual hydrocarbons in soil observe during growth of microorganisms on this soil.

In the article the results of investigation of oxidation processes of crude-oil by bacteria of genus Pseudomonas: Pseudomonas mendocina H-3, Pseudomonas sp. H-7, Pseudomonas stutzeri H-10, Pseudomonas aeruginosa H-14, Pseudomonas alcaligenes H-15 and Pseudomonas sp H-16. It was shown that these microorganisms are capable to oxidize oil’s hydrocarbons and oil products. It means that the bacteria may be used for bioremediation of oil-pollutant soils.

In this work carbonized rice husk  was used as carbon-based solid matrix in the preparation of composite materials modified with Fe3O4 particles. Aim of this study is to exploit the advantages and shortcomings of using a real biomass as starting material for the preparation of sorbents for CO2 capture applications. Sorption capacity of the obtained composite materials was tested on fixed-bed  microreactor.
