摘　　要：依据煤基合成油C5~C7烯烃组分氢甲酰化产物的分布特点,提出了相应正构C6~C8醛的2种分离工艺,采用Aspen Plus流程模拟软件,以NRTL热力学方程作为物性方法,对2种分离工艺进行模拟以及工艺参数的优化。模拟结果表明2种分离工艺都能满足分离要求,关键组分分离工艺比顺序分离方案约节能12%。优化后的工艺可为C5~C7烯烃氢甲酰化产物分离的工业化提供数据支持,并为煤制油高碳烯烃的精细化应用奠定基础。According to the distribution characteristics of hydroformylation products of C5~C7 olefins in coal-based synthetic oil,two separation processes of C6~C8 aldehydes were put forward.By using Aspen Plus process simulation software and NRTL thermodynamic equation as physical property method,the two separation processes were simulated and the process parameters were optimized.The simulation results show that the two separation processes can meet the separation requirements,and the key component separation process can save about 12%energy compared with the sequential separation scheme.The optimized process can provide data support for the industrialization of C5~C7 olefin hydroformylation product separation,and lay a foundation for the fine application of coal to oil high carbon olefins.
