摘要: Method of making BTX compounds including benzene, toluene, and xylene, including feeding heavy reformats to a reactor containing a composite zeolite catalyst. The composite zeolite catalyst includes a mixture of nanocrystalline Beta zeolite (Nano-Beta) comprising crystal size in the range of 10 to 40 nm and ZSM-5. The Nano-Beta, the ZSM-5, or both include one or more impregnated metals. The method further includes producing the BTX compounds by simultaneously performing transalkylation and dealkylation of the heavy reformate in the reactor. The composite zeolite catalyst is able to simultaneously catalyze both the transalkylation and dealkylation reactions.
