【摘要】 以扩孔、灼烧后的改性硅胶作为载体,将含有V、Cr、Mo、P、K的活性组份物均匀浸渍于载体上,得到V-Cr-Mo-P-K系间二甲苯氨氧化催化剂(NT08#),在100 t/a间苯二甲腈中试装置进行生产试验,流化反应床特征反应温度(浓2#)390~400℃,投料比(摩尔比)空气∶氨∶间二甲苯=38∶7∶1,产品收率达到了91.3%。更多还原

【Abstract】 Using the improved silica gel as carrier,dipping the multiple active ingredients which included V,Cr,Mo,P,K components in the carrier,then the V-Cr-Mo-P-K series m-xylene ammoxidation catalyst(NT08#) were obtained.The productive experiment was carried on the 100 t/a isophthalonitrile produce line,the characteristic reaction temperature of the fluid-bed reactor was 390～400 ℃,the material molar ratio of air ∶ammonia ∶m-xylene was 38 ∶7 ∶1.The result showed that the yield of isophthalonitrile could reach 91.3%.更多还原
