Abstract
A high pore volume solid sorbent material of low cracking activity and comprising a select group of metal additives to immobilize accumulated vanadium compounds deposited on the sorbent material in a heavy oil feed visbreaking zone is described and the conditions employed to effect demetallization and decarbonization of the heavy oil feed to produce vaporous products boiling up to about 1000.degree. F. Deposition of metal contaminants within the pores of the high pore volume material is encouraged by restricting the volume of the sorbent pores filled with oil feed to within the range of 1/4 to 2/3.
