Abstract: The extrusion molding process for the preparation of Fe-Mo oxide,which is the catalyst for the ammoxidation of methanol to hydrogen cyanide,is studied.The effects of different molding additives on the mechanical strength and activity of the catalyst are investigated.Combined with the specific molding process and characterization test results,the optimal molding conditions for the catalyst are selected as follows:the mass ratio of powder/water is 0.15-0.30,the dosages of sesbania powder,nitric acid and methylcellulose is 1%,5% and 2%,respectively.The catalyst prepared under the optimum conditions has been tested for 200 hours,and the results indicate that both the activity and mechanical strength of catalyst are quite stable,which provides important reference for scale-up industrial production.
