【Abstract】 The synthesis of Fe-Mo system catalyst and its catalytic activity were investigated.The influence of some factors in preparation process,such as ratio of Mo to Fe,addition of Cr,Co and Bi,feed method in coprecipitation,as well as the property and the composition of carriers of catalysts, on the yield of formaldehyde and the hot point temperature of the reaction bed was discussed. on the basis of obtained results,three types of catalysts were prepared. By using these catalysts,the yield of formaldehyde reaches 85%～88%.更多还原
