摘要：

A heterogeneous 2D dynamic model of a stopped flow fixed bed reactor for gas phase ethylene polymerisation has been constructed and validated. The reactor contains two solid phases with accumulation of mass within the reactor bed and the experiments modelled are of very short duration (0.1-75 s). There is a good fit between measured data and calculated values, and the model results allow us to interpret the experimentally observed temperature rises. Higher than expected catalyst temperatures are found towards the reactor centre and exit which are due to the initial intensity of the polymerisation reaction. (C) 2012 Elsevier B.V.
