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进料覆盖已发表的论文，对由炼油厂原料（如轻循环油（LCO））生产重要石油化工产品（例如苯，甲苯和二甲苯（BTX））的催化剂进行了综述。诸如四氢萘和萘衍生物之类的模型化合物实验提供了53-55％的BTX总产量。由于不可避免的气体形成和其他C _9+的存在，从未获得更高的产量形成了-烷基苯。对于四氢化萘，最好的催化剂是在沸石H-Beta上由Ni，CoMo，NiMo或NiSn构成的那些。对于萘衍生物，最好的催化剂是在沸石H-Beta甲硅烷基化条件下由W和NiW构成的催化剂。在最佳实验条件下，真实饲料的总BTX产量高达35％。由于进料中存在其他类型的可竞争催化位点的烃，因此从未达到更高的收率。最好的催化剂是那些由Mo，CoMo或NiMo在H-B沸石上形成的催化剂。通过将ZSM-5添加到载体中或与其他催化剂的混合物中获得了一些改进。
