摘要/Abstract

摘要： A new kinetic model for commercial unit of toluene disproportionation and C9-armatiocs
transalkylation is developed based on the reported reaction scheme. A time based catalyst
deactivation function taking weight hourly space velocity (WHSV) into account is
incorporated into the model, which reasonably accounts for the loss in activity because of
coke deposition on the surface of catalyst during long-term operation. The kinetic
parameters are benchmarked with several sets of balanced plant data and estimated by the
differential variable metric optimization method. Sets of plant data at different operating
conditions are applied to make sure validation of the model and the results show a good
agreement between the model predictions and plant observations. The simulation analysis of
key variables such as temperature and WHSV affecting process performance is discussed in
detail, giving the guidance to select suitable operating conditions.
