촉매가 하키퍽 또는 동전 모양의 매우 편평한 원통체인 L형 칼륨 제올라이트는 KO/SiO및 SiO/AlO의 비를 조절하고 제올라이트가 결정화되는 혼합물에 소량의 2가양이온, 예를들면 마그네슘 또는 바륨을 포함시키므로써 제조할 수 있다. 생성된 제올라이트는 짧은 채널 길이를 가지며, 방향족화 촉매에 대한 기재로서 특히 유용하다. 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.
