CATALYST FOR HYDRODESULFURIZATION ISOMERIZATION OF LIGHT HYDROCARBON OIL, METHOD FOR PREPARATION THEREOF, AND METHOD FOR HYDRODESULFURIZATION ISOMERIZATION OF LIGHT HYDROCARBON OIL USING THE CATALYST

摘要

A catalyst for conducting hydrodesulfurization and isomerization of a lighthydrocarbon oil at the same time, which comprises a carrier comprisingzirconium oxide or zirconium hydroxide, 1 to 3 mass % in terms of sulfur,relative to the total weight of the catalyst composition, of sulfate radicaland, relative to the total weight of the catalyst composition, (I) 0.05 to 10mass % of palladium, (II) 0.05 to 10 mass % of palladium and 0.05 to 10 mass %of platinum, or (III) 0.05 to 10 mass % of nickel, and has a specific surfacearea after burning and stabilization at 550 to 800 ~C of 50 to 150 m2/g; amethod for preparation of the catalyst; and a method for hydrosulfurizationisomerization of a light hydrocarbon oil using the catalyst.
