In present work the paths for obtaining the road oil bitumen are presented from the wastes of coal oil of the Karazhyra field. For the improvement of the quality of obtained bitumen the modification was carried out of elementary sulfur. The processes of modification by elementary sulfur allow to obtain the viscous road oil bitumen of high quality.
The effect is studied of duration of mechanochemical impact, as well as modification sequence and grinding on the acidic and catalytic properties of synthesized catalysts based on natural zeolite in the conversion of n-octane.It is shown that the highest catalytic activity in the conversion of n-octane has a modified nickel-and zinc-based catalyst zeolite and structured bentonite clay, subjected to mechanochemical treatment for 12 hours after the promotion.
Results of studies of humic substances in the quality of natural polymeric modifier for the coated palladium catalysts are presented in the paper, along with synthesis of new catalysts based on palladium – potassium humate, fixed on various inorganic carriers and their catalytic properties are studied. The catalysts may be placed in the following order according to activity: Pd-PHum/B-094 > Pd-PHum/Shungit (Sht), proc.1%КОН > Pd-PHum/Sht >> Pd-PHum/SiO2. More active and optimal are the catalysts of 0,8% Pd – Potassium’s Humat (1%)/B-94 and 0,8% Pd/Shungit 1% КОН.
This paper presents the results of a study on the catalytic activity and selectivity of nickel and palladium catalysts in hydrogenation reactions of nitro- and acetylene compounds. It was shown that the activity and selectivity of nickel catalysts in the hydrogenation of phenylacetylene depend on the nature of modifying additives (Cu, Zn, Ti, Cr, Bi, Ti–Cu, Mn, Fe), and the activity and selectivity of palladium catalysts based on a polymer of metal complexes depends on the method of their preparation. It was found that for certain concentrations of the active phase of palladium (0.8 wt.%) and the polymer of potassium humate (1.0 wt.%.) in the catalyst, where palladium and the polymer were deposited on bauxite-094 together, the catalyst exhibits the greatest activity and selectivity when hydrogenating phenylacetylene and potassium orthonitrophenolate.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
