Catalytic Refinement of Crude Shale Oil from the Oil Shale of the Kotsebinskoe Deposit

Abstract

The fractional distillation of crude shale oil was carried out for the removal of low-boiling components, and the yield of this fraction was 28 wt %. The catalytic removal of sulfur-containing compounds on a DN-200 commercial catalyst was performed. The degree of removal of sulfur compounds from crude shale oil was 94%. It was found that the shale oil after catalytic refinement satisfied the GOST [State Standard] requirements imposed on the concentration of sulfur compounds, and it can be used for the production of shale oil coke.
