AbstractMethods for preparing zeolites with the particle size of 50–200 nm using mechanical milling on bead mills (top-down approach) are analyzed. The milling can be described by a first-order rate equation, but mathematical models allowing prediction of the particle size and degree of crystallinity of zeolite after milling, based on the process p...

AbstractFormation of stable water-in-oil emulsions in light and heavy crude oils was shown to involve the buildup of interfacial layer characterized by increased contents of the main emulsifiers, asphaltenes and resins. An increase in the proportion of asphaltenes in the interfacial layer, nearly 4-fold for the light oil and 1.3-fold for the heavy ...

AbstractSpecific features of the distribution of vanadium and nickel during fractionation of heavy oil resins were examined using the example of heavy sulfurous oils from the Permian and Carboniferous deposits of the Volga-Urals oil and gas basin (Russian Federation). Fractionation of the resins was performed by silica gel column chromatography, fo...

AbstractThis article reports experimental data on a double-step technology for processing a model organic contaminant (m-cresol) adsorbed in the pores of an iron-containing carbon adsorbent (specific surface area 616 m2/g) under microwave irradiation. The first step comprised the decomposition of cresol into a hydrogen-containing gas and a carbon r...

AbstractThis review provides an analysis of modern process technologies for carbon dioxide removal from various gas mixtures (such as natural gas or hydrocarbon conversion gases in ammonia and syngas production facilities), as well as from flue gases generated during the combustion of carbon-containing feedstocks in power plants. The review also di...

AbstractThe paper describes a method developed for the oxidation of organosulfur compounds using organic peroxides generated in situ under the action of atmospheric oxygen on gasoline fraction after reforming. Naphtha reformate that contained dibenzothiophene as a model substrate was subjected to oxidative desulfurization by organic peroxides gener...

AbstractThe study investigates the effects of nickel introduction methods on the properties of a hybrid cobalt catalyst in a combination of Fischer–Tropsch synthesis and the hydroprocessing of the synthesized products. At 240°C, 2 MPa, and syngas WHSV 1000 h–1, the catalytic performances were compared, the products were analyzed for the hydrocarbon...
