Abstract
A catalyst for hydroprocessing is described, which comprises a carrier having supported thereon a group VI metal and/or a group VIII metal of the periodic table, in which the carrier comprises an inorganic refractory substance selected from the group consisting of alumina alone and alumina containing at least one of silica, magnesia, and calcium oxide, Y type zeolite having a unit lattice constant of 2.425 to 2.445 nm, zinc oxide, and, if desired, a boron compound, which catalyst exhibits improved cracking and desulfurization activities and has a long life.
