실험 절차

In Chinese Patent application CN93103817.1, Lanzhou Petrochemical Research Institute discloses a catalyst represented by a formula of MoBiFeWX1X2X3X4, wherein X1 is Co or Ni, X2 is at least one element selected from alkali metal or alkaline earth metal, X3 is at least one element selected from zinc, phosphorus, arsenic and boron, X4 is at least one element selected from silicon, aluminum, and titanium, based on the numbers of Mo atom being 12, the amount of Bi is 0.5˜4, Fe is 0˜8, W is 0˜4, X1 is 1˜8, X2 is 0.05˜3, X3 is 0˜4, and X4 is 0˜16. During the preparation of the catalyst, molybdenum oxide is used as a raw material to replace part of the ammonium molybdate raw material, and basic bismuth carbonate is used as a raw material to replace part of the bismuth nitrate raw material, and no pore-forming agent is necessary. The active ingredients are homogenously mixed with a silica micro-powder at a predetermined ratio, then silica gel is added thereinto and the mixture is band extruded, the extruded product is fired at 460° C. for 6 hours to produce the finished catalyst. Assessment on the catalyst is performed in a stainless steel pipe (Φ25.4 mm) packed with 1.0 L of the catalyst, a gas mixture with 10 wt % of propylene, 73 wt % of air and 17 wt % of steam is passed therethrough at a space velocity of 60 h−1(STP), acrylic acid and acrolein are produced with a yield of 93.2% under a propylene conversion ratio of 98.5% at a reaction temperature of 315° C., while the yield of COx is 4.2%.
