Shiyou Xuebao, Shiyou Jiagong/Acta Petrolei Sinica (Petroleum Processing Section)(2011)
Abstract
制备了CoMo/γ-Al2O3、NiMo/γ-AlzO3和NiW/γ-AlzO33种不同金属配伍的加氢催化剂,在连续流动固定床微反装置上对其芘的加氢活性以及产物分布选择性进行评价,并考察在原料芘中添加吡啶对催化剂芘加氢性能的影响.结果表明,在相同反应条件下,NiMo/γ-Al2O3催化剂对芘的加氢活性较高,NiW/γ-Al2O3催化剂上的芘加氢转化率受吡啶的影响最小;相同芘转化率下,CoMo/γ-Al2O3催化剂上的芘中间环加氢产物选择性较高.
