Abstract

Fly ash was chemically converted into zeolites. The conversion process not only eliminates the disposal problem of coal wastes but more importantly turns the waste material into a useful one. It was shown that fly ash can be converted into two forms of zeolites: P and faujasite, by varying the treatment condition. In addition, zeolite P was found to form earlier with higher treatment temperatures and adding quartz increased the amount of zeolite P formed. Seeding of faujasite was also studied.
