Experimental Study on Using Fuxin Natural Zeolite to Prepare Molecular Sieves

摘要

In this paper, the natural zeolite as raw material, zeolites was prepared by organic amines hydrothermal synthesis. The results are characterized by SEM and nitrogen adsorption / de-commanded test,and study the influence of the aging time, crystallization temperature and crystallization time on zeolite crystallization. The results showed that using natural zeolite as raw material and butylamine as templating agent, average pore size of 0.77nm, the relative crystallinity of 96.34% of the zeolite was prepared in the hydrothermal system. Optimal aging time is 12h, crystallization time is 48h, crystallization temperature is 170 °C.
