FCC轻汽油非贵金属二烯烃选择加氢催化剂

Non-noble metal diene selective hydrogenation catalyst of FCC light gasoline

采用非贵金属镍基二烯烃选择加氢催化剂,以催化裂化汽油不大于C6馏分(干点不大于75℃)为原料,在50~60℃,1.5 MPa,液体空速为2.0~4.0 h-1,氢气/原料体积比为12~24的条件下,进行选择性加氢反应。结果表明,反应中二烯烃转化率为100%;叔戊烯质量分数增加率始终大于2%;反应至800 h后,C5单烯质量分数减少量小于1%。

Selective hydrogenation was carried out with the light distillation of FCC gasoline as feedstock,hydrogenation catalyst and the compatible processes were used under the(reaction) conditions of 50～60()℃,1.5()MPa,space velocity(2.0～)(4.0()h^(-1)) and hydrogen/oil volume ratio 12~24.The results showed that the diene conversion reached 100%,the reactive C_5 olefin increased 2% and C_5 monoene decreased 1%.
