Catalysts to produce the important petrochemicals like benzene, toluene, and xylene (BTX) from refinery feedstocks, like light cycle oil (LCO) are reviewed here by covering published papers using model mixtures and real feeds. Model compounds experiments like tetralin and naphthalene derivatives provided a 53–55% total BTX yield. Higher yields were never attained due to the inevitable gas formation and other C₉₊-alkylbenzenes formed. For tetralin, the best catalysts are those conformed by Ni, CoMo, NiMo, or NiSn over zeolite H-Beta. For naphthalene derivatives, the best catalysts were those conformed by W and NiW over zeolite H-Beta silylated. Real feeds produced a total BTX yield of up to 35% at the best experimental conditions. Higher yields were never reached due to the presence of other types of hydrocarbons in the feed which can compete for the catalytic sites. The best catalysts were those conformed by Mo, CoMo, or NiMo over zeolite H-Beta. Some improvements were obtained by adding ZSM-5 to the support or in mixtures with other catalysts.

本文通过使用模型混合物和实际原料发表的论文，对从轻循环油 (LCO) 等炼油原料中生产苯、甲苯和二甲苯 (BTX) 等重要石化产品的催化剂进行了综述。四氢化萘和萘衍生物等模型化合物实验提供了 53-55% 的 BTX 总收率。由于不可避免的气体形成和其他C ₉₊ -烷基苯的形成，从未获得更高的产率。对于四氢化萘，最好的催化剂是由 Ni、CoMo、NiMo 或 NiSn 与 H-Beta 沸石相一致的催化剂。对于萘衍生物，最好的催化剂是W和NiW在H-Beta硅烷化沸石上的催化剂。在最佳实验条件下，真实饲料的 BTX 总产量高达 35%。由于进料中存在可能竞争催化位点的其他类型的碳氢化合物，因此从未达到更高的产率。最好的催化剂是 Mo、CoMo 或 NiMo 与 H-Beta 沸石相一致的催化剂。通过将 ZSM-5 添加到载体中或与其他催化剂混合，获得了一些改进。
