ABSTRACT:
Moisture- and ash-free coking coal is micronized and admixed with a recycle oil, whereafter it is rapidly hydrogenated and one portion of the residue of the fractional distillation of the hydrogenation product is sent to hydrotreating, together with hydrogen. Conventional catalysts can be used both for the hydrogenation and the hydrotreating.
A gaseous fraction, consisting of water vapor, hydrogen sulphide, ammonia and C1-C4 hydrocarbon is obtained along with gasoline.
Gasoil can be obtained together with gasoline.
