Claims
- 1. A process for hydrotreating a hydrocarbon oil feedstock, said process comprising hydrotreating said feedstock in the presence of a hydrotreating catalyst consisting essentially of an activated carbon, said activated carbon 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 about 54.ANG. .

- 4. The process of claim 1 wherein said activated carbon possesses a pore area in the 100.ANG. to 400.ANG. pore diameter range of at least about 18 square meters per gram.
- 5. The process of claim 1 wherein said activated carbon possesses a pore area in the 100.ANG. to 400.ANG. pore diameter range of at least about 50 square meters per gram.
- 6. The process of claim 1 wherein said activated carbon possesses an Alpha value of at least about 2.9.
- 7. The process of claim 1 wherein said activated carbon possesses an Alpha value of from about 3 to about 6.
- 8. The process of claim 1 in which the hydrocarbon oil feedstock is characterized by a distillation boiling point range such that the fraction boiling at over 650.degree. F. comprises at least 70% of the hydrocarbon oil.
- 9. The process of claim 1 wherein said process is carried out in a fixed bed reactor.
- 10. The process of claim 1 wherein said hydrotreating conditions include a temperature of from 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 from about 0.1 to about 10.sup.- hr.sup.-1 WHSV.
- 11. The process of claim 1 wherein said hydrotreating conditions include a temperature of from about 600.degree. F. to about 1000.degree. F., a pressure of from about 500 psig to about 2500 psig and a space velocity of from about 0.2 to about 5 hr.sup.-1 WHSV.
- 12. The process of claim 1 wherein said hydrotreating conditions include a temperature of from about 700.degree. to about 900.degree. F., a pressure of from about 1000 psig to about 2000 psig, and a space velocity of from about 0.3 to about 1.0 hr.sup.-1 WHSV.
- 13. The process of claim 1 wherein said hydrotreating includes demetallation, desulfurization, reduction of pentane insoluble asphaltenes, and the reduction of carbon residue of the feedstock.
- 14. The process of claim 13 wherein said demetallation is characterized by at least a 23% reduction of the combined content of nickel and vanadium compounds present in the feedstock.
- 15. The process of claim 13 wherein said demetallation is characterized by at least a 50% reduction in the combined content of nickel and vanadium compounds present in the feedstock.
- 16. The process of claim 13 wherein said demetallation is characterized by at least a 59% reduction in the combined content of nickel and vanadium compounds present in the feedstock.
- 17. The process of claim 13 wherein said desulfurization is characterized by a reduction of at least 9.5% of the sulfur content of the feedstock.
- 18. The process of claim 13 wherein said reduction of carbon residue is characterized by at least a 13.5% reduction of the Conradson Carbon Residue.
- 19. The process of claim 13 wherein said reduction of pentane insoluble asphaltenes is characterized by at least a 10% reduction of the pentane insoluble asphaltene content.
- 20. The process of claim 1 wherein the hydrotreating conditions include a hydrogen circulation rate of from about 300 SCF H.sub.2 /bbl to about 6000 SCF H.sub.2 /bbl of feedstock.
