| 摘 要： | 为了考察高岭土焙烧前后性能的变化,将高岭土分别在200℃、400℃、600℃、和800℃进行焙烧,得到焙烧高岭土催化剂样品,并对催化剂进行TG-DTA、XRD和SEM等的分析及活性测试.结果表明,高岭土经过高温焙烧后转变为偏高岭土,高岭土的特征峰消失,同时孔道明显增多,甲醇转化率、二甲醚选择性和收率均提高.

| Abstract: | In order to investigate the performance changes of kaolin before and after calcination,the kaolin was calcined at 200 ℃, 400 ℃, 600 ℃, and 800 ℃ respectively to obtain kaolin catalyst.The catalyst was characterized by TG-DTA,XRD,SEM, etc,and tested in methanol to dimethyl ether.The results showed that the kaolin was transformed into metakaolin after high-temperature roasting;The characteristic peaks of kaolin also disappeared;At the same time,the number of pores increased significantly;The methanol conversion, dimethyl ether selectivity and yield were all improved. |
