METHOD FOR ISOMERIZATION OF HYDROCARBON, AND SOLID ACID CATALYST AND ISOMERIZATION SYSTEM FOR USE THEREIN

Title:

METHOD FOR ISOMERIZATION OF HYDROCARBON, AND SOLID ACID CATALYST AND ISOMERIZATION SYSTEM FOR USE THEREIN

Document Type and Number:

WIPO Patent Application WO/2000/034415

Kind Code:

A1

Abstract:

A method for isomerization of a hydrocarbon which comprises providing a solid acid catalyst comprising a carrier containing a part comprising zirconia and/or hydrated zirconia and sulfuric acid carried thereon, and contacting the catalyst with a hydrocarbon material having a water content of 5 ppm by weight or less, preferably 1 ppm or less, to thereby produce isomerized hydrocarbons; and a system for practicing the method. The isomerization method does not need the introduction of a chlorine-containing compound during the course of isomerization and uses a catalyst having high activity. The isomerization system comprises a dehydrating apparatus for the material, a vessel for catalytic reaction filled with the above catalyst, a separator for separating a reaction product into the hydrogen to be recycled and a hydrocarbon product, and a compressor which compresses the recycle hydrogen to feed it to the vessel for catalytic reaction.
