开展了20t/a规模工业双戊烯连续气相催化脱氢反应放大试验装置的设计和测试统计.在温度280～300℃、氮气流速2.0 L/min、工业双戊烯进料速度4.0 L/h时,上述催化脱氢反应可连续进行,工业双戊烯原料与脱氢粗产物的平均质量比为1.11.经真空精馏装置处理,脱氢粗产物极易被提纯精制.工业双戊烯原料与对伞花烃成品的质量比(即工业双戊烯单耗)分别为1.81(纯度99.0%以上)、1.69(98.0%以上)、1.54(96.0%以上)和1.45(90.0%以上).纯度99.5%对伞花烃成品的沸点、相对密度和折光指数分别为177.1℃、0.857 s/mL和1.490.该放大统计可为工业双戊烯生产对伞花烃的工程化或工业化开发提供服务.

A 20 t/a scale pilot experimental device for continuous gas-phase catalytic dehydrogenation of industrial dipentene was designed and tested.The catalytic dehydrogenation could be continuously carried out under the conditions of temperature 280-300℃,nitrogen flow rate 2.0 L/min,industrial dipentene flow rate 4.0 L/h.The average mass ratio of industrial dipentene to crude product(ks/kg)was 1.11.The crude product of dehydrogenation wag easily purified by the vacuum rectification apparatus.Mass ratio of industrial dipentene to p-cymene pmduct(kg/kg)was 1.81(purity over 99.0%),1.69(purity over 98.0%),1.54(purity over 96.0%)and 1.45(purity over 90.0%),respectively.The boiling point,relative density and refractive index of p-cymene product with 99.5%purty were 177.1℃,0.857 g/mL and 1.490,respectively.The pilot experimental statistics could provide services for engineering or industrialization development of P-cymene manufacture from industrial dipentene.
