| 摘 要： | 基于提高烯烃利用率和增产丙烯的目的,以催化裂化(FCC)干气和混合C4组合原料来制备丙烯,考察了混合比例、空速、反应温度等因素对产物分布的影响。结果发现,当以生产丙烯为目的时,混合比例和空速分别为3.3和118 m in-1时,丙烯收率可获得最大值33.2%(质量分数)。在350~675℃内,随温度升高,裂解深度增加,乙烯、丙烯等小分子烯烃含量增加,丁烯含量则是先减小,当温度高于600℃时又有所回升,推测高温下丁烷为烯烃的生成做了一部分贡献。

| Abstract: | To improve the utilization of olefins and maximize the yield of propene,propene is prepared with the combined feed of FCC dry gas and mixed C4.The reaction conditions,including mixing radio,space velocity and reaction temperature,are investigated.The yield of propene reaches a maximum of 33.2% when the mixing radio and space velocity are 3.3 and 118 min-1,respectively.Within the temperature range of 350-675℃,the content of ethene or propene increases with temperature,while the content of butene decreases first and goes up again above 600℃,and butane is supposed to contribute to the production of olefins at high temperature. |
