摘要
F- T反应产物具有广泛的碳数分布 ,近年来 ,F- T合成研究的重点转移到高选择性地合成重质烃 ( C+ 5以上 )产物 .综述了钴基催化剂应用于 F- T反应合成长链烃中链增长途径和 F- T合成选择性的关系 ,从理论上评述了能有效提高长链烃选择性的制备催化剂的方法 ,指出了采用蛋壳型催化剂、添加合适的助剂及选择具有规整孔道分布的中孔载体材料均有利于提高 F-
The product distribution of F T synthesis are broad.In the past decades many studies on Fischer Tropsch synthesis were focused on the synthesis of long chain hydrocarbon.The path of chain growth on co based catalysts and the control of product selectivity have been reviewed.The methods of preparing catalysts with high long chain hydrocarbon have been discussed.It is pointed out that employing eggshell catalysts,adding appropriate promoter and selecting middle aperture carriers are all in favor of improving the selectiveity for high chain hydrocarbon on Co based catalysts.
