Disclosed herein are catalysts useful for oxidation and ammoxidation of hydrocarbons. Such catalysts have the empirical formula BiMo.sub.a V.sub.b Sb.sub.c M.sub.d O.sub.x wherein a is 0.5-2, b is 0.12-3, c is 0.12-10, d is 0-0.5 and x is selected to satisfy the valence requirements of the other elements present. In such catalysts, M is one or more elements selected from Groups I-A, II-A, III-A, V-A, VI-A, I-B, IV-B, VI-B and VII-B of the Periodic Table. Catalysts according to the invention are prepared by forming a slurry of vanadium antimonate component, a bismuth molybdate component, and optionally the compound M and/or a support material, drying the slurry, and calcining to form the catalyst. Such catalysts are specifically useful for production of acrylonitrile from propylene, ammonia and an oxygen-containing gas.
本文揭示了用于氢氧化和氨氧化碳氢化合物的催化剂。这样的催化剂具有经验公式BiMo.sub.aV.sub.bSb.sub.cM.sub.dO.sub.x,其中a为0.5-2,b为0.12-3,c为0.12-10,d为0-0.5,x被选为满足其他元素的价需求。在这样的催化剂中,M是周期表的I-A,II-A,III-A,V-A,VI-A,I-B,IV-B,VI-B和VII-B组中选择的一个或多个元素。根据本发明制备的催化剂通过形成钒锑酸盐组分、铋钼酸盐组分和/或化合物M和/或支撑材料的浆料,干燥该浆料并焙烧以形成催化剂。这样的催化剂特别适用于从丙烯、氨和含氧气体生产丙烯腈。
