Process for the isomerisation of a paraffinic charge uses a catalyst containing a group VIB nitride and phosphorus as the active phase

摘要

The catalyst composition has a high activity and selectivity n isomerized products for the conversion of 7 - 10C normal paraffins, the charge preferably containing less than 100 ppm of sulfur. Process of isomerisation, under a pressure of hydrogen, of a charge containing 10C max. paraffins, in the presence of a catalyst comprising an amorphous support, phosphorus and a group VIB metal An Independent claim is also included for the preparation of the catalyst.
