Difunctional catalyst effective in wax hydroisomerization and process for preparing it |
摘要 |
Process for the hydroisomerization of n-paraffins in the presence of a difunctional catalyst which comprises: (a) a porous crystalline material isostructural with beta-zeolite selected from boro-silicate (BOR-B) and boro-alumino-silicate (Al-BOR-B) in which the molar SiO2:Al2O3 ratio is higher than 300:1; (b) one or more metal(s) belonging to Group VIIIA, selected from platinum and palladium, in an amount comprised within the range of from 0.05 to 5% by weight.
