Abstract The growing shortage of oil resources makes it necessary to find alternative energy sources. The leading place among them today belongs to biofuels, both due to sufficient and affordable resources, and relatively advanced technologies for their production. The requirements of modern standards for the quality of the resulting gasolines limit the content of aromatic […]
Abstract The paper gives a brief analysis of experimental work on the production of sorbents from various biological wastes in one process. The obtained sorbents are used without additional activation. In connection with such experimental material, the theoretical aspects of various processes in the channels and on the surface of the sorbent are considered. The […]
Abstract The paper deals with potential compositions developed for inhibiting scale deposition on oil refining equipment and pipelines based on inhibited hydrochloric acid, dispersant EС 9660A, laprol 4202- 2B-30 and water. The density of the produced compositions at 20 ºС is 1020-1050 kg/m3, the kinematic viscosity at 20 ºС is 30-40 mm2/s, the pour point […]
Abstract Spectrophotometric methods were used to study the reaction of complexation of tungsten with derivatives of o-hydroxythiophenol (HTPDs) {2-hydroxy-5-chlorothiophenol (HCTP), 2-hydroxy-5- bromothiophenol (HBTP) and 2-hydroxy-5-iodothiophenol (HITP )} in the presence of aminophenols. Aminophenols used were 2(N,N-dimethylaminomethyl)-4-chlorophenol (AP1) and 2(N,N- dimethylaminomethyl)-4-bromophenol (AP2), 2(N,N-dimethylaminomethyl) -4-iodophenol (AP3).Optimal conditions for the formation and extraction of mixed ligand complexes (MLC) […]
Abstract The article deals with the issue of secondary recycling municipal solid waste (MSW) into complex mineral fertilizers using domestic agricultural raw materials. Used in the recycling were slag from combustion of MSW and poor phosphorite. The nature of the decomposition of phosphorite 50-80% acid H2SO4 was studied at an acid consumption rate of 60-110%, […]
