  • Catalyst for hydrotreating of gas oil and method for hydrotreating of gas oil
    Patent number: 6821412
    Abstract: A catalyst for hydrotreatment of gas oil containing defined amounts of platinum, palladium, and in a support of an inorganic oxide containing a crystalline alumina having a crystallite diameter of from 20 to 40 Å. A method for hydrotreating gas oil containing an aromatic compound in the presence of the above catalyst at defined conditions. A method for catalytically hydrotreating gas oil (b.p. 160-400° C.) or blend oil, in a first desulfurization step at defined conditions using a catalyst with at least one Group 6a and Group 8 metal in a support of an inorganic oxide to regulate to a defined sulfur-containing compound content, and then carrying a second desulfurization step by catalytic reaction of the oil at defined conditions using a catalyst of platinum, palladium, and halogen with a support containing an alumina.
