The process of conversion of light alkanes into aromatic hydrocarbons on zeolite catalysts, modified with Zn, La, Fe and Zr was investigated in this work. The catalysts were tested in the conversion process of propane-butane and propane-propylene mixtures at atmospheric pressure, variation of temperature and space velocity (SV). It is observed that the maximum amount of aromatic hydrocarbons (34.6%) are formed in the conversion of propane-butane mixture over Zn-La-Fe-ZSMAl 2 O 3 catalyst at 550 o C, selectivity to aromatic hydrocarbons is 39,2%.

The paper presents the results of the study of hydrotreatment of hexane, decane and diesel oil fractions on a new aluminum oxide zeolite-containing catalyst KGO – 12, modified with metals with variable valence, phosphorus and lanthanum additives. The hydrotreatment process was studied in a high-pressure flow unit with a stationary catalyst bed at temperatures of 320 – 400° C, a pressure of 4.0 MPa, and a volumetric feed rate of 2 h-1. After hydrotreating the diesel fraction of oil on the KGO – 12 catalyst at 400° C, the sulfur content in the catalysate decreases from 0.141 to 0.0092%, and the solidification temperature decreases from minus 27 to minus 57° C. The study of the process of hydrotreatment of the n-alcanes diesel fraction on the KGO – 12 catalyst showed that hydrotreatment, hydroisomerization and hydrocracking reactions occur simultaneously. It is established that the developed KGO – 12 catalyst has a high activity in the process of hydrotreating the diesel fraction of oil and makes it possible to obtain low-setting low-sulfur diesel fuel.
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.
