Silicoaluminophosphate SAPO-34 molecular sieve nanocrystals have been prepared by a post-synthesis milling and recrystallization method, which is further proven to be universally applicable to other SAPO molecular sieves. The obtained SAPO-34 with reduced Si enrichment on the external surface shows considerably improved catalytic performance in the MTO reaction.
硅铝磷酸盐SAPO - 34分子筛纳米晶体通过合成后研磨和重结晶方法制备,该方法进一步证明普遍适用于其他SAPO分子筛。所获得的外表面硅富集减少的SAPO - 34在甲醇制烯烃反应中显示出显著改善的催化性能。
