Cracking of heavy carbonaceous liquid feedstocks utilizing hydrogen donor solvent |
摘要 |
Heavy carbonaceous liquid having a melting point below 250 DEG C. is upgraded to lighter products by hydrogen donor solvent cracking, using recycled solvent derived at least in part from a middle distillate fraction of either the heavy carbonaceous liquid or from the cracked products which is subjected to one or more catalytic hydroprocessing steps before recycling.
