摘要
使用氧化铁系催化剂,研究了乙苯脱氢制取苯乙烯中乙苯转化率和苯乙烯的选择性与温度、进料比的关系。实验证明,乙苯的转化率受温度和进料比的共同影响,在所研究的范围内,苯乙烯的选择性主要受温度影响,选择合适的进料比对提高转化率和选择性至关重要。
The relationships of the conversion of ethylbenzene dehydrogenation to styrene with iron oxide as catalyst, the selectivity of styrene and temperature and feed ratio are investigated. It has been proved that the ethylbenzene conversion is influenced by both temperature and feed ratio but the styrene selectivi- ty is mainly affected by reaction temperature. It is also important to improve the conversion and selectivity by selecting suitable feed ratio.
