从Ｂ０２催化剂绝热固定床的反应特征的分析出发，提出了开发等温固定床的设想。通过采用惰性填料多段稀释催化剂等方法，使Ｂ９０催化剂上丁烯氧化脱氢制丁二烯强放热反应床层达到等温。在Ｂ９０催化剂总稀释比为２时，采用三段稀释的催化剂的装填方式，丁烯转化率和丁二烯的选择性分别达到９１．４％和９６．５％，比Ｂ９０绝热床分别提高１１．４％和１．３％。如果能实现工业化。可带来很大的经济效益。
Starting from the analysis of the reaction characteristics of B02 catalyst adiabatic fixed bed, the idea of developing isothermal fixed bed was proposed. Through the use of inert filler multi-stage dilution of the catalyst and other methods, the B90 catalyst on the oxidation of butylene to butadiene strong exothermic reaction bed to achieve isothermal. When the total B90 catalyst dilution was 2, the three-stage dilute catalyst loading method was used, the butene conversion and butadiene selectivity reached 91.4% and 96.5% respectively, which were respectively 11 and 11 higher than that of B90 .4% and 1.3%. If you can achieve industrialization. Can bring great economic benefits.
