【摘要】：研究了含有石英成分的高岭土的活化方法,并采用水热法制备了干燥剂NaP分子筛。研究了碳酸钠对高岭土的活化效果、不同水热反应条件对NaP分子筛吸水率的影响,得到该高岭土的活化条件为:m(高岭土)∶m(碳酸钠)=1∶1、在750℃下煅烧2 h;制备NaP分子筛的优化条件为:n(SiO_2)/n(Al_2O_3)=4.0、n(Na_2O)/n(SiO_2)=1.4、n(H_2O)/n(Na_2O)=40、93℃下晶化8 h。
[Abstract]:The activation method of kaolin containing quartz was studied and the desiccant NaP molecular sieve was prepared by hydrothermal method. The activation effect of sodium carbonate on kaolin was studied. The effect of different hydrothermal reaction conditions on the water absorption of NaP molecular sieve was studied. The activation conditions of the kaolin were: m (kaolin sodium carbonate (): m () = 1: 1, calcined at 750 鈩，
