PROCESS FOR THE HYDROLIQUEFACTION OF HEAVY HYDROCARBON OILS AND RESIDUA

摘要

A process is set forth for the solvent extraction and hydroliquefaction of heavy hydrocarbon oils and residua having an API gravity at 60.degree.F of less than 20.degree. in the presence of a hydrogen atmosphere and a hydrogen donor solvent at elevated temperature and pressure. Alternately, the hydrocarbon feed can be subjected to a vacuum distillation before solvent extraction or the liquefaction can be catalyzed in-situ. The process results in improved oil production and greater denitrogenation desulfurization and demetallization.
