Abstract

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.

First claim

The invention claimed is:

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.

2. The hydroisomerization catalyst according to claim 1 , wherein the organic template-containing zeolite is at least one selected from the group consisting of a zeolite ZSM-22, a zeolite ZSM-23, and a zeolite ZSM-48.

3. The hydroisomerization catalyst according to claim 1 , wherein the inorganic oxide is alumina.

4. The hydroisomerization catalyst according to claim 1 , wherein the metal supported on the support is platinum and/or palladium.

5. The hydroisomerization catalyst according to claim 1 , wherein a molar ratio of silicon atoms to aluminum atoms ([Si]/[Al]) in the organic template-containing zeolite is 10 to 400.

6. A method of dewaxing a hydrocarbon oil comprising contacting, in the presence of hydrogen, a hydrocarbon oil containing normal paraffins having 10 or more carbon atoms, with the hydroisomerization catalyst of claim 1 , thereby converting a portion or all of the normal paraffins to isoparaffins.

7. The method according to claim 6 , wherein the hydrocarbon oil is at least one selected from the group consisting of hydrocracked vacuum gas oils, hydrocracked atmospheric residual oils, hydrocracked vacuum residual oils, hydrodesulfurized vacuum gas oils, hydrodesulfurized atmospheric residual oils, hydrodesulfurized vacuum residual oils, slack waxes, dewaxed oils, paraffinic waxes, microcrystalline waxes, petrolatum, and Fischer-Tropsch synthesis waxes.

8. A process for producing a hydrocarbon comprising contacting, in the presence of hydrogen, a hydrocarbon feedstock containing normal paraffins having 10 or more carbon atoms, with the hydroisomerization catalyst of claim 1 .

9. The process according to claim 8 , wherein the hydrocarbon feedstock is at least one selected from the group consisting of hydrocracked vacuum gas oils, hydrocracked atmospheric residual oils, hydrocracked vacuum residual oils, hydrodesulfurized vacuum gas oils, hydrodesulfurized atmospheric residual oils, hydrodesulfurized vacuum residual oils, slack waxes, dewaxed oils, paraffinic waxes, microcrystalline waxes, petrolatum, and Fischer-Tropsch synthesis waxes.

10. A process for producing a lube base oil comprising contacting, in the presence of hydrogen, a hydrocarbon feedstock containing normal paraffins having 10 or more carbon atoms, with the hydroisomerization catalyst of claim 1 , under conditions that give substantially 100 mass % conversion of the normal paraffins, as defined by the following expression (I):
