Abstract
Processes for reforming, and in particular aromatising, hydrocarbons from a petroleum source may be carried out by contacting the hydrocarbons with a catalyst of a zeolite KL impregnated with a metal promotor such as platinum, in which the zeolite crystals are of hockeypuck shape. The processes have a good yield and selectivity for the desired reformed products and the catalyst is stable, is associated with a low rate of coke formation, and has a long catalytically active life before regeneration is required.
