Title:
METHOD OF ISOMERIZING HYDROCARBON
Document Type and Number:
WIPO Patent Application WO/2003/080768
Kind Code:
A1
Abstract:
A method of isomerizing a hydrocarbon, comprising, in the presence of hydrogen, bringing a hydrocarbon containing C7 or C8 saturated hydrocarbons (known as heavy naphtha) in a proportion of 50 wt.% or more into contact with a solid acid catalyst having a platinum group metal component borne on a support, the support comprising as metal components at least one Group IV metal component selected from the group consisting of titanium, zirconium and hafnium and at least one Group VI metal component selected from the group consisting of tungsten and molybdenum. This isomerization is preferably performed at 190 to 250 ° C under a pressure of 0.8 to 10 MPa. With respect to the catalyst, a solid acid catalyst wherein the support further comprises aluminum as a metal component is preferably used.
