AbstractThe effect of the properties of modifying additives (Mg and Ca) introduced into nanosized catalytic dispersions on the occurrence of three-phase Fischer–Tropsch synthesis has been studied. It has been found that the introduction of Mg and Ca into the catalytic dispersion composition contributes to a redistribution of oxygen-containing produ...

AbstractThe natural gas amine sweetening process to remove acid impurities has been analyzed, the related problems have been considered, and ways of their solution have been proposed. Problems such as optimization of compositions of both the amine solution and the acid gases to be eliminated, contamination of amine solutions with different impuriti...

AbstractResults of a study of the synthesis of hydrocarbons (HC) from CO and H2 in the presence of a commercial Co–Al2O3/SiO2 catalyst at 6.0 MPa and a reaction gas recycle ratio of 2.2–6.0 for 1000 h have been described. Under these conditions, the catalyst deactivation rate depends on the selectivity for synthetic C35+ long-chain HCs (SLCHCs). An...

AbstractThe chemical, electronic, and supramolecular structures of asphaltenes, isolated from the atmospheric–vacuum distillation residue of Western Siberian crude oil, have been experimentally and theoretically studied. The chemical structure of asphaltenes has been studied by IR, UV, and visible spectroscopy. Using UV–visible absorption spectra, ...

AbstractA comparative analysis has been made of the physicochemical properties and structural-group composition of acids isolated from crude oils of the Anastasievsko-Troitskoe (Krasnodar krai, Russia) and Naftalan (Azerbaijan) oil fields. For each crude, the following three fractions of acids have been obtained by vacuum fractionation and analyzed...

AbstractThe catalytic activity of zeolites of the FAU, MFI, and BEA framework types with different SiO2/Al2O3 ratios, which are dispersed in the reaction medium, has been studied in the liquid-phase cracking of n-alkanes at a temperature of 300–350°С and a hydrogen pressure of 7 atm. It has been found that a BEA zeolite catalyst with a SiO2/Al2O3 r...

AbstractIn this work, the thermal cracking of n-decane was carried out under supercritical pressure. To comprehensively investigate the thermal cracking, a developed online-sampling experimental method was constructed through the directly cooling of cracked fuel at high temperature. The results show, that the novel method can effectively terminate ...

AbstractA scheme for the combined processing of coal to produce synthetic jet fuel is proposed and experimentally verified. It has been established that using an approach including coal coking followed by gasification, Fischer–Tropsch synthesis, and hydroisomerization, the resulting kerosene fractions are characterized by low density values (0.741–...
