将煤系高岭土在750℃下煅烧2 h，使其转变为偏高岭土，加入过量10%质量分数为20%的盐酸在90℃下酸浸2 h，氧化铝溶出率达到72.6%；合成NaX分子筛的体系组成是：n(SiO2)/n(Al2O3)为3.0、n(Na2O)/n(SiO2)为1.9、n(H2O)/n(Na2O)为40，室温老化24 h后，加入理论产量10%的NaX分子筛原粉作为晶种，在95℃水热条件下晶化9 h，得到晶化产物，产物为较纯净的NaX分子筛。

The coal series kaolin was turned into metakaolin by calcination at 750℃for 2 h, then the hydrochloric acid whose concentration was 20%was added into the metakaolin overdose in 10%and leached at 90℃for 2 h, the alumina leaching ratio was 72.6%;then the synthesis system of NaX molecular sieves was that n(SiO2)/n(Al2O3) being 3.0, n(Na2O)/n(SiO2) being 1.9 and n(H2O)/n(Na2O) being 40, aging at room temperature for 24 h, adding 10%NaX molecular sieve raw powder of theoretical output as seeds, crystallization by hydrothermal method at 95℃for 9 h, the products were purer NaX molecular sieves.
