摘　　要：研究间戊二烯选择性加氢制正戊烯工艺及催化剂,提升正戊烯产品选择性。结果表明,Pd-Pb-K/γ-Al_(2)O_(3)贵金属催化剂加氢活性和选择性好,氢气和双烯烃物质的量比是控制正戊烯选择性的关键因素。在三段注氢固定床加氢工艺中,在较低温度和压力条件下,控制n(H_(2))∶n(双烯烃)及三段注氢比例,可保证双戊烯转化率,并有效提升正戊烯产品选择性。Process and catalyst study on selective hydrogenation of isoprene to n-pentene were carried out in the article.The results show that Pd-Pb-K/γ-Al_(2)O_(3) noble metal catalyst has good hydrogenation activity and selectivity,and the selectivity of n-pentene can be improved by strictly controlling the molar ratio of hydrogen to diolefin and hydrogen distribution in three-stage hydrogen injection process.
