Hydrocracking of heavy oils in presence of petroleum coke derived from heavy oil coking operations

摘要

A process for the conversion of a heavy hydrocarbon oil in the presence of hydrogen and iron-petroleum coke catalyst is described in which the iron-petroleum coke catalyst is prepared by grinding petroleum coke particles and particles of an iron compound in oil to form an additive slurry or paste and mixing the petroleum coke-iron oil slurry or paste with the heavy hydrocarbon oil to form a feedstock to hydroconverter.
