摘要
以工业V2O5和工业磷酸为基本原料，以醛（如苯甲醛）、醇（如正辛醇）或醛-醇混合物为还原剂，合成出前躯体后成型并老化，制备出丁烷流化床氧化制顺丁烯二酸酐V—P-O催化剂。最佳工艺条件为：V2O5粒度小于5μm；n（P）／n（V）=1．2；磷酸质量分数91．7％～92．9％。流化床活性评价结果表明，顺丁烯二酸酐收率大于44％。
Using industrial vanadium oxide and phosphoric acid as materials,aldehyde(such as benzaldehyde) or alcohol(such as n-octyl alcohol),or their mixture as reductant,in fluidized bed the V-P-O catalyst for n-butane oxidation to maleic anhydride was synthesized.The optimization process conditions were that the granule size of vanadium oxide was less than 5 μm,n(P)/n(V) was 1.2 and the mass fraction of phosphoric acid was 91.7%～92.9%.In fluidized bed the activity test results showed that the yield of maleic anhydride was more than 44%.
