1·Many of the raw materials used in the petrochemical industry are unsaturated hydrocarbons, such as ethylene, propylene, butene and butadiene.
在石油化学工业中所用的许多原料是不饱和烃类，如乙烯、丙烯、丁烯和丁二烯。
2·In the developing the oxidative dehydrogenation of butene process, it is found that the effect of heat feedback through reactor wall is different between laboratory and commercial scale reactors.
在丁烯氧化脱氢反应过程的开发放大中，发现实验室反应器和工业规模反应器通过反应器壁的热反馈存在不同的影响。
3·Through side-stream test, the result of butadiene removal by DD-1, service life, butene loss, and the influences of reaction velocity and reaction temperature on the catalyst are analyzed.
通过侧流试验分析了DD - 1脱除丁二烯的效果、使用寿命和丁烯损耗情况、反应空速和反应温度对催化剂的影响。
4·The oxidative dehydrogenation of butane to butene and butadiene was studied by using conventional fixed bed reactor (FBR), inert membrane reactor (IMR) and mixed inert membrane reactor (MIMR).
比较了固定床反应器（FBR）、惰性膜反应器（IMR）与混合式惰性膜反应器（MIMR）用于丁烷氧化脱氢制丁烯和丁二烯反应的性能。
5·The results show that top ethylene contains only 1% butene, and bottom liquid phase contains less than 1% ethylene.
结果表明，塔顶乙烯中只含小于1％的1-丁烯； 塔底液相中乙烯含量也小于1％。
