以糠醛为原料，在以柱形铝粒力载体的Ｖ２Ｏ５—Ｍ０Ｏ３—Ｆｅ２Ｏ３—Ｐ２Ｏ５催化剂上进行了 固定床直接气相催化氧化以制备顺丁烯二酸酐，催化剂先在３４０°活化４８小时。当在３３０°， １立升催化剂上容气量力４０立升／分，糠醛进料量为３０—４０克／小时 时，糠醛转化率为 ９０％，单程收率为６１—６５％（如按反应的糠醛重量算收率力８２—８７％，催化剂生产能力 为２０－２５克／立升催化剂小时，催化剂的寿命在１０００小时以上，均能满足工业生产要求。 此外还对水气的影响，反应诱导期、反应中途冷却及催化剂的再生等进行了考察。作者还进 行了以浮石力载体的试验，其收率比用小铝柱的约低１５％，也进行了以浮石力载体的沸腾床 中的试验，其收率一般均比固定床中为低。
Furfural was used as the raw material to prepare maleic anhydride by gas-phase catalytic oxidation on V2O5-M0O3-Fe2O3-P2O5 catalyst with columnar aluminum particles. The catalyst was activated at 340 ° for 48 hours. Furfural conversion was 90% and the single-pass yield was 61-65% when capacity was 40 liters / min at 330 °, 1 liter of catalyst and furfural feed was 30-40 g / h The reaction yield of furfural weight of 82-87%, the catalyst production capacity of 20-25 g / liter catalyst hours, the catalyst life of more than 1,000 hours, can meet the requirements of industrial production.In addition to the impact of moisture, Reaction induction period, reaction mid-cooling and catalyst regeneration were investigated.The authors also conducted a test with pumice force carrier, the yield was about 15% lower than with a small aluminum column, but also carried out with pumice stone carrier boiling The test bed, the yield is generally lower than the fixed bed.
