| Abstract: | The technological advances of toluene disproportionation and transalkylation process(TDTA),shape selective didproportionation of toluene(TSD)and dealkylation process of heavy aromatics,domestic and abroad,were reviewed.Combined process of TSD with benzene /C9 aromatics transalkylation process obvious technological advantages of increasing p-xylene production and reducing production cost.Along the development of natural gas industry,PX production technology by methylation of toluene with methanol is worth while to be focused on and wuld be expected to have promising industrial prospect. |
