摘要
Abstract
A reactor model for propane dehydrogenation was developed using ACM according to kinetic data,and the results showed that the calculated values were in good consistent with the operation data.According to the reactor model,the reactor temperature distribution,propane conversion,and the variation of reaction product fraction along the radial and axial directions of the reactor were analyzed.The reactor model established by ACM was encapsulated and imported into Aspen plus,and the simulation of propane four series dehydrogenation reaction section(1#～4#)was established,and the effects of reactor outlet temperature and H2/HC in the device feed on the reaction process were analyzed.The analysis results showed that increasing the inlet temperature of reactors 3#and 4#was more effective than reactors 1#and 2#in improving propane conversion;increasing the inlet temperature of reactor 4#had the least decrease in propylene selectivity,followed by reactor 3#.Lowering the H2/HC in the device feed is beneficial to propylene production and improving propylene yield,but it also accelerate the formation of coke on the catalyst and cause the catalyst activity to decrease,which requires a balanced consideration of propylene selectivity and catalyst life.关键词
