-
The Mo-Bi-Fe-P/sepiolite catalysts were prepared by a coprecipitation method and characterized by XRD and BET techniques. Their catalytic activities were investigated in a selfe made fixed bed reactor as function of temperature, pore size distribution of the catalysts and space velocity(GHSV) of the feed gas. The results showed that at the conditions of V(propylene):V(ammonia):V (air)=1:1.05:11, GHSV=580 h-1, reaction temperature ca. 530℃, the catalyst had pore size ranged in 40~100 nm, acrylonitrile in yield being of 81.4% and propylene conversion of 98.5% could be achieved.
