ABSTRACT:
A combination coal liquefaction-gasification-naphtha reforming process wherein the slurry containing substantially the entire yield of normally solid dissolved coal produced in the liquefaction zone comprises substantially the only hydrocarbonaceous feed for the gasification zone and wherein a portion of the naphtha produced in the liquefaction zone is passed through the reforming zone for conversion to gasoline with the remainder of the naphtha being burned as fuel within the process. The amount of hydrocarbonaceous material charged to the gasification zone is established so that the thermal efficiency of the process is substantially unaffected by changes in the ratio of naphtha passed through the reforming zone to naphtha burned as process fuel. The thermal efficiency of the process is maintained at a high level regardless of minor variations in normally solid dissolved coal yield by changing the ratio of naphtha passed through the reforming zone to naphtha burned as process fuel.
