| Abstract: | The pseudo-homogeneous two-dimensional model of the fixed-bed reactor for dimethyl oxalate(DMO) hydrogenation to ethylene glycol(EG) was established based on the reaction kinetics.The partial differential equations of the model were solved by Matlab and Excel.The effects of reactor temperature,LHSV and reactor diameter on the conversation of DMO,the selectivity to EG,the hot-spot and the space-time yield of EG were investigated.And the distributions of concentration and temperature were presented,which prov... |
