Title:
N-PARAFFIN SELECTIVE HYDROCONVERSION PROCESS USING BOROSILICATE ZSM-48 MOLECULAR SIEVES
Document Type and Number:
WIPO Patent Application WO/2011/056469
Kind Code:
A3
Abstract:
The present invention is directed to processes using a borosilicate ZSM-48 as a catalyst for the selective hydroconversion of heavy normal paraffins into lighter normal paraffin products, with minimal formation of isoparaffins. The borosilicate ZSM-48 molecular sieve has a mole ratio of between 40 and 400 of silicon oxide to boron oxide, synthesized using novel structure directing agents.
