ABSTRACT:
A liquefaction process for coal lignite or heavy oil is disclosed utilizing a hydrogen-donor solvent. The preferred hydrogen-donor solvent is recovered as a vapor from the liquefaction mixture. The preferred method for converting the vapor into active hydrogen-donor solvent form involves passage of the vapor over a catalyst bed positioned in the vapor space of the catalyst vessel. Novel apparatus for so positioning the catalyst bed is also disclosed.
