摘要
The present invention relates to process of a selective disproportionation of toluene and a disproportionation and transalkylation toluene and C9+ aromatics to mainly solve the problems in the prior arts of the large amount of recycle stream, high energy consumption. or harsh requirement for reaction feedstocks. The present invention has better solved these problems by the technical solution using a process for selective disproportionation of toluene to produce mixed xylenes containing a high concentration of p-xylene, and subsequent disproportionation and transalkylation of C9+ aromatics and toluene to produce benzene and the mixed xylenes which are in the thermodynamic equilibrium. The process is applicable to the industrial production.
