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.
Claims21
A process for demetallizing a metal-containing hydrocarbon feedstock, comprising:
- contacting said metal-containing hydrocarbon feedstock with hydrogen and a material having a porosity of less than 0.3 cc/gram, a surface area of less than 5 m.sup.2 /gram, an average pore diameter in excess of 1,000 .degree.A. and a pore distribution in which at least 40% of the pores have a size of greater than 10,000 .degree.A., at least 60% of the pores have a size in excess of 1,000 .degree.A., and less than 20% of the pores have a size of less than 100 .degree.A., said contacting being effected at demetallization conditions to deposit metals present in said feedstock on said material.
A process for demetallizing a metal containing hydrocarbon feedstock, comprising:
- contacting said metal containing hydrocarbon feedstock with hydrogen and a coke selected from the group consisting of calcined coke and green coke, said coke having a porosity of less than 0.3 cc/gram, a surface area of less than 5 m.sup.2 /gram, an average pore diameter in excess of 1,000 A and a pore distribution in which at least 40% of the pores have a size of greater than 10,000 A, at least 60% of the pores have a size in excess of 1,000 A, and less than 20% of the pores have a size of less than 100 A, said contacting being effected at demetallization conditions to deposit metals present in said feedstock on said coke.
