摘要
本文利用中压（３．ＯＭＰａ）固定床流动反应装置研究了不同Ｃｏ含量对ＭｏＯ３／ＴｉＯ２─Ａｌ２Ｏ３催化剂加氢脱硫性能的影响．结果表明，少量Ｃｏ助剂的引入可显著提高催化剂的加氢脱硫活性，但对加氢活性影响较小．Ｃｏ／Ｃｏ＋Ｍｏ原子比在０．２５～０．４５范围内催化活性最高．
hiophene hydrodesulfurizaation (HDS ), cyclohexene hydrogenation (HYD )and Benzene hydrogenation (BHD) activities of CoMo/(TiO2--Al2O3) are measured in a fixed --bed reactor with 0. 5g catalyst at 3.0 MPa H2 pressure. The results reveal that CoO and NiO can greatly improve the HDS activity of Mo/TiO2--Al2O3. The catalyst exhibits the highest activity when Co/Co+Mo atomic ratio is in the range of 0. 25￣0. 45. The measurement of the activities of the catalysts shows that the activities of CoMo/(TiO2--Al2O3), NiMo/(TiO2--Al2O3) are always higher than that of Mo/Ti2O3--Al2O3.
