The method of preparing the new catalytic dehydration of glycerol to acrolein species

The present invention relates to a new method of species catalytic dehydration of glycerol to acrolein, a fixed bed reactor was placed in a microwave generating apparatus, the preheated feedstock gasification reaction into the fixed-bed reactor, a fixed bed reactor containing the catalyst absorbing, continuous glycerol dehydration reaction in the presence of acrolein absorbing catalyst, the catalytically active component consists of absorbing conventional core-shell structure coated with an oxide material load absorbing composition. The present invention utilizes the uniformity of microwave heating, inhibit the formation of hot spots during the reaction to improve the stability of the catalyst during the reaction, the reaction procedure is simple, the apparatus can operate stably for a long.
