摘要:
The invention relates to a molecular sieve catalyst composition, to a method of making or forming the molecular sieve catalyst composition, and to a conversion process using the catalyst composition. In particular, the invention is directed to a making a molecular sieve catalyst composition by forming a slurry by combining a molecular sieve, a binder and a matrix material, wherein the slurry has a pH, above or below the isoelectric point of the molecular sieve. The catalyst composition has improved attrition resistance, particularly useful in a conversion process for producing olefin(s), preferably ethylene and/or propylene, from a feedstock, preferably an oxygenate containing feedstock.
摘要(中):
本发明涉及分子筛催化剂组合物,制备或形成分子筛催化剂组合物的方法,以及使用该催化剂组合物的转化方法。 特别地,本发明涉及通过组合分子筛,粘合剂和基质材料形成浆料来制备分子筛催化剂组合物,其中所述浆料具有高于或低于分子筛等电点的pH。 催化剂组合物具有改善的耐磨性,特别适用于从原料,优选含氧化合物原料生产烯烃,优选乙烯和/或丙烯的转化方法。
