Catalytic cracking of the semicoking tar of coal from the Shubarkol deposit

Abstract

The results of studies on the application of a catalytic composition synthesized based on finely dispersed silicon-containing natural clay from the Narynkol deposit (Republic Kazakhstan) and a water-soluble silicon salt (Ba–Al–Si) to the process of the catalytic cracking of the semicocking tar of coal from the Shubarkol deposit are reported. It was established that, in the presence of this composition, the yield of a gasoline fraction at a temperature of 420°C and an argon pressure of 3.0 MPa was 34%, and the yield of a diesel fraction was 50%; this fact makes it possible to consider coal tar as a potential raw material for the production of motor fuel components.
