Title:
METHOD FOR ISOMERIZING STRAIGHT-CHAIN PARAFFIN
Document Type and Number:
Japanese Patent JPH02142739
Kind Code:
A
Abstract:

PURPOSE: To industrially and advantageously isomerize a 4-10C n-paraffin into a paraffin having side chains without adding H2 gas into a reaction system by using a solid catalyst in a mixed fluid of the reactant and product in a supercritical state.

CONSTITUTION: A 4-10C n-paraffin is introduced into a reactor filled with a solid catalyst supporting Pt on Y type zeolite, etc., and isomerized under conditions of higher reaction temperature and reaction pressure than the critical temperature and pressure of a mixed fluid consisting of the reactant and product in the reaction vessel without adding H2 gas into the reaction system. The mixed fluid of the unreacted reactant and the product emerging from the reactor is then decompressed to take out the paraffin as an isomerized paraffin product having side chains.
