PROBLEM TO BE SOLVED: To provide a hydrogenation isomerization catalyst which enables acquisition of hydrocarbons suitable for base oils for lubricants and/or fuel oils in a high yield from raw hydrocarbon oils containing n-paraffins, has a sufficiently high isomerization activity and sufficiently controls a decomposition activity.SOLUTION: The hydrogenation isomerization catalyst is used in hydrogenation isomerization of hydrocarbons and contains a support comprising a zeolite modified with at least one metal selected from Na, K, Cs, Mg, Ca, Ba and K and baked through a thermal history including heating at temperatures of ≥350°C and at least one inorganic oxide selected from alumina, silica, titania, boria, zirconia, magnesia, ceria, zinc oxide, phosphorous oxide and their compound oxides comprising at least 2 kinds of combinations thereof and at least one metal selected from elements of the groups 8 to 10 in the periodic table, molybdenum and tungsten. The zeolite is prepared from an ion-exchanged zeolite obtained by ion-exchanging an organic template containing zeolite having an organic template and a ten-membered one-dimensional pore structure in a solution containing an ammonium ion and/or a proton, and the initial heating of the heating at temperatures of ≥350°C in the thermal history to which the zeolite is subjected is in a range of 350-450°C. |
