The use of supercritical solvents in crude oil fraction conversion

Abstract

Abstract Nowadays, the production of liquid fuel faces such problems as the matching of the final product with the world standards. To solve these problems, the development of novel technologies and highly effective catalysts for crude oil processing and hydrotreatment is of great interest. In the current work, we provide the combined methodology for the conversion of sulfur-containing oil fractions and heavy hydrocarbons based on the application of supercritical solvent and polymer stabilized oxide catalysts. The mixture of propanol-2 and n-hexane in the supercritical state was used as a solvent in this work. It was found that such combination allows the effective C-C and C-S bond breacking. In this paper we describe the studies on the influence of solvent composition and catalyst on the conversion of two widely used oil model compounds (anthracene and dibenzothiophene).
