Composition useful in the hydroprocessing of a hydrocarbon feedstock

摘要

A composition having a substantial or material absence of or no phosphorous and comprising a support material, a metal compound and either a hydrocarbon oil or a polar additive or a combination of both a hydrocarbon oil and polar additive. The polar additive has particularly defined properties including having a dipole moment of at least 0.45. The composition is useful in the hydroprocessing of hydrocarbon feedstocks, and it is especially useful in the hydrotreating of vacuum gas oils and petroleum resid feedstocks.

1. A composition having less than 0.1 wt. % phosphorous and comprising a metal-impregnated support material comprising a calcined support material impregnated with a metal compound, wherein said metal-impregnated support material is dried at a drying temperature in the range of from 50° C. to 200° C. but not calcined, prior to impregnation therein of a polar additive, wherein said polar additive excludes heterocompounds that include sulfur, and has a dipole moment of at least 0.45, and wherein said polar additive has a boiling point in the range of from 50° C. to 275° C., to provide a polar additive impregnated composition and wherein said composition comprising said metal-impregnated support material and said polar additive has undergone a hydrogen treatment at a temperature in the range from 100° C. to 225° C. followed by sulfiding.
