摘要
A molecular sieve based catalyst and its application for selective hydroisomerisation of long linear and/or branched paraffins are claimed. It consists of a matrix comprising of 5 wt.% of a hydro-dehydrogenating element chosen from a group composing of non precious metals of group VIII, metals of group VIB, niobium and a molecular sieve containing a mono or a bi-dimensional porous network such that the pores openings accessible are limited by 10 oxygen atoms and the distance between the pores being less than 0.70 nm. The zeolite is the catalyst comprising of the zeolite and 0.5 wt.% of platinum, when subjected to the standard isomerisation test of n-heptadecane yields a selectivity of 70% of isomerised products for a conversion of 95%.
