摘要
讨论了在Langmuir-Hinshelwood动力学情况下,单颗粒催化剂中活性非均匀分布对颗粒内传递-反应行为的影响。应用正态函数表述颗粒内的活性非均匀分布,并就活性分布位置和宽度对活性影响以及多解区域内的催化剂颗粒活性等方面进行了深入分析,进一步加深了对颗粒内传递-反应行为的认识,进而为催化剂中的活性分布设计提供导向性建议。
The effect of activity distribution on the performance of transfer-reaction in catalyst pellets has been investigated in the case of Langmuir-Hinshelwood kinetics. The activity distribution was represented by the normal function and a deeper insight into the effects of distribution position and width on activity of catalyst pellets and the activity in the case of multiplicity was given. This gives a deeper understanding of transfer-reaction and, therefore, may be helpful in the guiding of the design of cata...
