Abstract
A process for preparing an alkylaromatics isomerisation catalyst comprising at least 0.01% wt of platinum on a carrier comprising of from 1 to 9 wt % of ZSM-12 and inorganic binder, which process comprises treating the carrier with an impregnation solution comprising a cationic platinum compound and having a pH of more than 9, and subsequently drying and calcining the impregnated carrier at a temperature of from 200 to 420° C.; and a process for the isomerisation of alkylaromatics with the help of catalyst thus obtained.
