【Abstract】 The concept of catalytic distillation in three phase fluidized plate tower was proposed. The fluidized catalytic distillation for synthesis of methylal was conducted in a single plate tower, where a strongly acidic ion exchange resin was placed as catalyst. The vapor liquid mass transfer coefficient in the process was measured. The effect of some factors such as vapor flow rate, liquid flow rate and catalyst concentration on the coefficient were investigated.更多还原
