Selective disproportionation method of toluene, disproportionation and transalkylation method of toluene and C9 and C9+ aromatic hydrocarbon

摘要

This invention, mainly mass playbacks style of known technology, regards, the disproportionation of selective disproportionation and toluene and C₉⁺ aromatics of the toluene in order to solve the problem of the prerequisite where the consumption of high energy or reaction raw materials are harsh and the method of alkyl exchange. This invention solved these problems selective disproportionation of the toluene for the mixture xylene production which includes p-kishiren of high density, with C₉⁺ aromatics for benzene and the mixture xylene production which continue and the disproportionation of toluene and the technical solution method which uses alkyl exchange method. It can apply to the production with respect to industry the aforementioned method.
