天然沸石与合成沸石分子筛相比,具有更好的热稳定性、耐酸性和机械强度。虽然纯度不高,但由于价格远远低于合成分子筛,所以它的应用在国外已取得很大进展。我国有丰富的沸石矿物资源,其中有不少储量大、品位好的矿床。近年来,沸石矿 Compared with synthetic zeolite, natural zeolite has better thermal stability, acid resistance and mechanical strength. Although its purity is not high, its application has made great progress in foreign countries because the price is much lower than that of synthetic molecular sieve. China is rich in zeolite mineral resources, including many large reserves, good grade deposits. In recent years, zeolites
