摘要
Abstract
For a single reaction tube in a tubular fixed-bed reactor,a one-dimensional pseudo-homogeneous model of HPPO epoxidation reaction is built.The effects of n(C3H6)∶n(H2O2),H2O2 WHSV,temperature of heat-removing media and feed concentrations of H2O2 on epoxidation are investigated.The results show that n(C3H6)∶n(H2O2)has great influence on the hot spot temperature of the reaction tube.Too low H2O2 WHSV can easily lead to temperature runaway in the reactor.n(C3H6)∶n(H2O2)can be controlled at 6-9,H2O2 WHSV can be controlled at 0.3-0.6 h-1,and the feed concentration of H2O2 is lower than 30%(w)to improve H2O2 conversion,PO selectivity and space time yield,and reduce bed hot spot temperature and H2O2 decomposition rate.关键词
