【摘要】：研究了含有石英成分的高嶺土的活化方法,并采用水熱法制備了干燥劑NaP分子篩。研究了碳酸鈉對(duì)高嶺土的活化效果、不同水熱反應(yīng)條件對(duì)NaP分子篩吸水率的影響,得到該高嶺土的活化條件為:m(高嶺土)∶m(碳酸鈉)=1∶1、在750℃下煅燒2 h;制備N(xiāo)aP分子篩的優(yōu)化條件為: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，
