    摘要： Disclosed is a process for the preparation of a faujasite zeolite. A starting zeolite of the faujasite structure having a silica to alumina ratio of from 4.5 to 6.5 and an alkali level of less than 1.5% wt is steam calcined to produce an intermediate zeolite. The intermediate zeolite is treated with an acidified solution having specificately defined characteristics.
