This research pursues an objective to explore the composition and physicochemical characteristics of the domestic adsorbent obtained through processing alumina waste from the local industry upon completion of testing in the course of purification of hydrogen-containing gas from chlorine-containing compounds. Also, changes in the quantitative ratio of the main chemisorption products of harmful impurities (NaCl, AlCl 3 , AlCl 3 .6H 2 O and AlxCly (OH) z .nH 2 O) depending on modifiers of various nature were determined. The NaCl content in the adsorbents used rose symbatically in the concentration of main centers due to surface aluminates and sodium carboaluminate in the initial samples. The amount of coke-like deposits with a high hydrogen content С n Н 1.75-1.8n satisfactorily correlated with the concentration of strong secondary acid sites arising from the formation of aluminum chlorides and hydroxychlorides. The accumulation of coke-like deposits with graphitic structure during the testing of adsorbents under industrial conditions for gas purification in the regeneration of catalyst reforming did not exceed 1.5% of the mass.
Мо and Co-Mo catalysts for processes of hydrodesulfurization and hydrogenation of aromatic hydrocarbons in the composition of kerosene, deasphaltisate and natural gas are considered.
The dynamics of the accelerated formation of corrosion products of equipment in the process of obtaining diesel and oil fractions from sour oil with a high concentration of resinous asphaltic substances and derivatives of petroleum acids are investigated in this work. The following experimental data is obtained: the genesis of the phase composition during the synthesis of granules of the protective layer from kaolin phosphate mass, followed by their modification with Ni 2+ ions in order to control the surface acidity and the hydrogenating function focused on the conversion of reactive alkenes. The mechanism and conditions for the formation of samples of catalysts of the protective layer of the core type contain ing the weight of 2.5%, are discussed. NiO in the surface layer, and 5 times less in the inner part of the granules which consist of particles of clay mineral cemented Al (H 2 PO 4) 2 , as well as other products of dissolution of kaolinite and hydromica with phosphoric acid, are also studied. The results of the study of the efficiency of removal of corrosive iron and impurity elements of petroleum origin in granules of the developed protective layer are presented. It has been established that the use of granules of a protective layer in optimal shape and size, together with a reduced tendency to form a solid crust of sediments, limited the increase in pressure drop on the layer of CoMo catalyst of hydrofining oil distillates and the deasphalted vacuum residue of highsulfur tarry oil.
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.
