反应器上部气相空间温度? 反应器上部气相空间温度也就是甲醇蒸汽进入催化剂床层的温度。 改变甲醇蒸汽进料经过反应器冷管换热后进入反应器上部气相空间,和直接进入反应器上部气相空间的比例 the temperature of the upper vapor phase in the reactor that means the temperature of the gaseous methanol enters in the catalyst bed. in order to change the ratio of the gaseous methanol feed enters the upper vapor phase after passing the cooling tube in the reactors and the gaseous methanol feed enters the upper vapor phase directly. 比例的问题,麻烦指点中译英 查看更多
