Long chain (C7+) paraffins are isomerized over a large pore, highly siliceous zeolite catalyst such as zeolite Y or ZSM-20 having a structural silica:alumina ratio of at least 10:1.

Long chain (C7+) paraffins are isomerized over a large pore, highly siliceous zeolite catalyst such as zeolite Y or ZSM-20 having a structural silica:alumina ratio of at least 10:1. The use of the highly siliceous zeolite inhibits the degree of cracking and also permits weaker hydrogenation components such as palladium to be used in the catalyst.
