采用涂覆法将 HZSM-5负载到堇青石整体式载体上,研究了载体的孔直径、浆液固含量、溶剂及黏结剂对负载量和负载牢固度的影响。实验结果表明,载体的孔直径大、浆液固含量高和以乙醇为溶剂可以提高 HZSM-5在整体式载体上的单次负载量,但是却降低了 HZSM-5在整体式载体表面的负载牢固度,黏结剂硅溶胶可以大幅度提高活性组分在整体式载体表面的负载牢固度。在甲醇制汽油反应中,HZSM-5/整体式催化剂表现出较高的甲醇转化率,在380℃时汽油收率达到30.53%。
採用塗覆法將 HZSM-5負載到堇青石整體式載體上,研究瞭載體的孔直徑、漿液固含量、溶劑及黏結劑對負載量和負載牢固度的影響。實驗結果錶明,載體的孔直徑大、漿液固含量高和以乙醇為溶劑可以提高 HZSM-5在整體式載體上的單次負載量,但是卻降低瞭 HZSM-5在整體式載體錶麵的負載牢固度,黏結劑硅溶膠可以大幅度提高活性組分在整體式載體錶麵的負載牢固度。在甲醇製汽油反應中,HZSM-5/整體式催化劑錶現齣較高的甲醇轉化率,在380℃時汽油收率達到30.53%。

HZSM-5 was loaded on the cordierite monolithic,and the effect of porous size of the carrier,solid content in slurry,solvent and binder on the loaded amount and loaded quality has been studied.The results show that the big channel, high solid content and the addition of ethanol solvent could increase the loaded amount of the active components in each immobilization process,yet the loaded quality of HZSM-5/monolithic catalyst was decreased.While silica sol could significantly increas ethe loaded quality of HZSM-5 on monolithic.In conversion of methanol to gasoline,HZSM-5/ monolithic catalyst exhibited high methanol conversion,and oil yield could reach 30.53% at 380 ℃.
