2-丁烯液态临氢异构制1-丁烯热力学分析
Journal Title: Science Paper Online - Year 2007, Vol 2, Issue 12
Abstract
本文利用文献数据和Aspen Plus软件计算相结合的方法，在313.15~363.15 K的温度和0.7~1.6 MPa的压力范围内，研究2-丁烯液态临氢异构制1-丁烯体系的反应热力学特征。结果表明，双键异构反应为吸热反应，顺反异构反应为放热反应，但热效应不大；异构反应受热力学平衡的限制，而加氢反应为不可逆反应。提高温度将有利于提高2-丁烯的转化率；氢的加入量需要控制，以保证1-丁烯的选择性和收率。从各组分的沸点差异看，2-丁烯临氢异构制1-丁烯过程可采用反应精馏耦合技术，以突破热力学平衡限制，同时实现1-丁烯的分离和浓缩。
