Hierarchical SAPO-34 catalysts with abundant intracrystalline mesopores have been prepared using morpholine as the template combined with a cheap nonsurfactant cationic surfactant. Significantly, the hierarchical SAPO-34 catalysts exhibit more than 5-fold improved lifetime and 12% enhanced selectivity for ethylene and propylene compared to conventional microporous counterparts in methanol-to-olefin (MTO) reactions.
采用吗啉作为模板剂,结合一种廉价的非表面活性剂阳离子表面活性剂,制备了具有丰富内孔中孔的分级 SAPO-34 催化剂。显著地,与传统的微孔对应物相比,在甲醇制烯烃(MTO)反应中,分级 SAPO-34 催化剂的寿命提高了 5 倍以上,乙烯和丙烯的选择性提高了 12%。
