HYDROTREATMENT OF DIESEL FRACTIONS ON A MODIFIED ALUMINUM-NICKEL-MOLYBDENUM CATALYST KGO-12

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.

Intrinsic kinetic study of 1-butene isomerization over magnesium oxide catalyst via a Berty stationary catalyst basket reactor

The intrinsic kinetics of 1-butene isomerization over a commercial MgO catalyst was studied by using a Berty-type reactor (gradient-less recycle reactor) without limitations of heat-, external mass-, and internal mass-transfers.
