【摘要】 分子筛催化剂是当前研究较多的一类流化床催化剂，工业上通常采用双铝基溶胶、硅铝复合溶胶、磷铝溶胶等作为粘结剂，通过喷雾造粒制备分子筛类微球催化剂。流化床工艺不仅要求催化剂具有良好的催化性能，还要有较好的耐磨性能、良好的球形度和适宜的粒径分布以满足实际的工业生产。粘结剂和载体的选择、浆液的制备工艺、喷雾造粒机的进口和出口温度、雾化器转速和成型的后处理都会对催化剂耐磨性能、粒径分布、球形度和催化性能产生巨大影响。本文以工业研究较为成熟的FCC催化剂和MTO催化剂为例，从催化剂浆液组分优化、喷雾造粒成型过程优化以及催化剂后处理优化三个方面总结当前流化床分子筛催化剂耐磨性能研究进展，为其它耐磨流化床催化剂的开发提供一定的参考。更多还原

【Abstract】 Molecular sieve catalysts are one of the most studied fluidized bed catalysts.Molecular sieve microsphere catalysts are typically prepared by spraydrying processes, which used double aluminum-based sol, silica-aluminum composite sol, phosphorus-aluminum sol, etc.as binders in industry.The fluidized bed catalysts required not only good catalytic performance, but also superiorattrition resistance, favourable sphericity and appropriate particle size distribution to match the actual industrial manufacturing.The attrition resistance, particle size distribution, sphericity and catalytic performance of molecular sieve catalysts are significantly affected by the selection of binders and supports, the slurry preparation processes, the inlet and outlet temperatures of the spraydrying processes, the atomizer speed and the post-processing of the catalysts.The current research progresseson improving the attrition resistance of fluidized bed molecular sieve catalysts(FCC catalysts and MTO catalysts are taken as examplesin this paper) are summarized from three aspects including optimization of catalyst slurry components, optimization of spraydrying processes and post-processing of catalysts, and provide some references for the research & development of other attrition resistant fluidized bed catalysts.更多还原
