Abstract

The increased content of aromatic hydrocarbons impairs environmental and technological properties of fuels: increased tendency towards carbon formation; increased particulate emissions from the engines. In order to reduce the content of aromatics in the oil fractions we use dearomatization process performed based on the hydrogenation of benzene to cyclohexane over Rh-promoted catalyst. The process is conducted at a rhodium catalyst that operates under mild conditions and has greater selectivity for compounds with a terminal double bond. In this work we developed synthesis method of carbon matrix and active ingredients promoted methods. Synthesized Rh carbon catalysts inflicted on clay and the carbonized apricot pits. The influence of Rh content in the hydrogenation of benzene. Identified the optimal conditions for the hydrogenation reactions of aromatic hydrocarbons over Rh catalysts inflicted on various matrixes. Investigated the physic-chemical characteristics of the promoted carbon materials.
