Abstract
Heavy oil is hydrotreated by processing with hydrogen in the presence of a catalyst composition comprising an activated carbon component having a specified range of pore volume distribution and average pore diameter, a molybdenum or tungsten component and a cobalt or nickel component to reduce the content of nickel and vanadium therein and to achieve demetallation and conversion of the carbon residue for producing a lighter oil.
Claims17
A process for hydrotreating a hydrocarbon oil feedstock characterized by a distillation boiling point range such that the fraction boiling at over 650.degree. F. comprises at least 97% of the hydrocarbon oil, said process comprising contacting said feedstock under hydrotreating conditions including a temperature of between about 500.degree. F. to about 1200.degree. F., a pressure of from about 0 psig to about 4000 psig and a space velocity of about 0.1 to about 10-hr-1 WHSV in the presence of a catalyst composition comprising (a) an activated carbon component derived from lignite possessing a pore volume in the 100.ANG. to 400.ANG. pore diameter range of at least about 0.08 cc/g., and an average pore diameter of from about 15.ANG. to 100.ANG., and (b) a molybdenum or tungsten component and (c) a cobalt or nickel component.
