通过浸渍法制备了Co/SBA-15、Mo/SBA-15和Co-Mo/SBA-15催化剂,对催化剂的孔结构、物相及表面酸性进行了表征,测定了硫化催化剂上噻吩加氢脱硫及 1-己烯加氢异构的反应性能,并与工业Co-Mo/γ-Al2O3催化剂进行了对比. 结果表明, Co-Mo/SBA-15催化剂表面具有较强的B酸中心,且对噻吩加氢脱硫具有较高的催化活性; 而Co-Mo/γ-Al2O3催化剂表面主要为较强的L酸中心,对 1-己烯加氢具有较高的催化活性. Mo/SBA-15催化剂的B酸酸性较强,但同时具有较高的 1-己烯加氢活性,故它对 1-己烯骨架异构的催化活性不高. Co-Mo/SBA-15催化剂的加氢活性相对较低, 1-己烯容易在其较强的B酸中心上发生骨架异构反应,具有潜在的工业化应用前景.
