Abstract
This invention relates to a catalyst for hydrorefining and/or hydroconversion of hydrocarbon-containing feedstocks that contain compounds whose boiling point is higher than 520° C. and that contain sulfur and possibly metals, as well as its use in hydrorefining and/or hydroconversion processes of heavy feedstocks. A petroleum residue of atmospheric distillation (RA) or of vacuum distillation (RSV) or a deasphalted oil (DAO) are representative feedstocks of the feedstocks treated within the scope of this invention.
Claims19
A catalyst comprising
- a porous substrate having mesopores, and
- catalytic metal consisting essentially of, 1 to 30% by weight of at least one catalytic group VIB metal in a quantity expressed in % by weight of oxide relative to the weight of the final catalyst, and
- above 0 to 2.2% by weight of at least one non-noble group VIII catalytic metal in a quantity expressed in % of oxide relative to the weight of the final catalyst
- and wherein the atomic ratio between the non-noble group VIII element and the group VIB element is less than 0.4, the total pore volume, measured by mercury porosimetry, is between 0.5 and 1.5 cm3/g, and the distribution of mesopores of the substrate is centered on a diameter of 140 to 170 Å, and the specific surface of the catalyst is greater than 50 m2/g.
