摘要

The hydroisomerization catalyst of the present invention is a catalyst used for hydroisomerization of a hydrocarbon, including a support including a calcined zeolite modified with at least one metal selected from the group consisting of Na, K, Cs, Mg, Ca, Ba, and K, and having a thermal history that includes heating at 350° C. or more, and at least one inorganic oxide selected from the group consisting of alumina, silica, titania, boria, zirconia, magnesia, ceria, zinc oxide, phosphorus oxide, and a composite oxide containing a combination of at least two or more of these oxides; and at least one metal supported on the support and selected from the group consisting of elements belonging to Groups 8 to 10 of the periodic table, molybdenum and tungsten.

1. A catalyst used for hydroisomerization of a hydrocarbon, comprising a support and at least one metal selected from the group consisting of elements belonging to Groups 8 to 10 of the periodic table, molybdenum, and tungsten, wherein
the support comprises a calcined zeolite, which is modified with Cs, the calcined zeolite being prepared by calcining an ion-exchanged zeolite, that has not previously been heated at 350° C. or more, at a temperature within a range of 350 to 450° C., the ion-exchanged zeolite being obtained by ion exchange of an organic-template-containing zeolite, which comprises an organic template and has a 10-membered ring one-dimensional porous structure, in a solution containing ammonium ions and/or protons; and at least one inorganic oxide selected from the group consisting of alumina, silica, titania, boria, zirconia, magnesia, ceria, zinc oxide, phosphorus oxide, and a composite oxide containing a combination of at least two or more of these oxides.
