摘　　要：根据裂解混合碳四选择加氢制丁烯工艺和催化剂评价研究结果,提出一种提高1-丁烯收率的加氢工艺流程设计方案。该工艺流程采用烃类蒸汽裂解装置所产混合碳四做原料,经过两段加氢反应器进行选择加氢,将混合碳四中的炔烃和1,3-丁二烯加氢生成富含1-丁烯的碳四物流。流程模拟计算结果表明,加氢后,1,3-丁二烯含量小于10×10-6,1-丁烯选择性大于55%。According to the performance test results of selective hydrogenation of cracking C4 mixture for butane production,this paper proposes a hydrogenation process design for improving 1-butene yield.Crude C4 from steam cracking unit is used as the feedstock,and two-stage hydrogenation reactor is used to selectively hydrogenate the alkynes and 1,3-butadiene in crude C4 to 1-butene-rich C4 stream.Process simulation results show that after two-stage hydrogenation,the content of 1,3-butadiene can be reduced to less than 10ppm and the selectivity of 1-butene is greater than 55%.
