乙烯氧乙酰化催化剂颗粒异形化的研究

Research on Specialization of Pellet Shape of Catalyst for Acetoxidation of Ethylene

采用颗粒异形化技术研究了球状颗粒开孔孔径和孔数目对乙烯氧乙酰化催化剂活性和选择性的影响。结果表明，适当增加颗粒外表面积，可以提高催化剂的活性和选择性，且单孔颗粒的催化剂性能优子多孔颗粒。

The effects of hole diameter and hole number on the activity and selectivity of catalystpellet for acetoxidation of ethylene were studied experiTnentally by specialization of pelletshape。 The results showed that the catalyst activity and selectivity could be improved by pro- perly increasing the outer surface of catalyst pellet, and that the performance of single- holecatalyst pellet is better than that of multiple-hole pellet.
