Abstract
A metal containing hydrocarbon feedstock, such as a heavy residue, is contacted with hydrogen and a material characterized by low porosity, less than 0.3 cc/gram; low surface area, less than 5 m.sup.2 /g; high average pore diameter, greater than 1,000 Angstroms; and a high distribution of large pores, at least 40%, and preferably 50 to 80% of pores greater than 10,000 Angstroms. A preferred material is coke.
