Currently, Domestic triphen production mainly use direct steam gasoline, naphtha by Catalytic oxidation, extract separate production processes. Inadequate supply of raw materials, Benzene and its derivatives production by the high degree of restriction. Our textile industry has developed rapidly in recent years, and each year need to import substantial quantities of benzene derivatives products downstream , and imports increased rapidly, so it’ s very important to search for a new means of production. Product triphen in GLP is light hydrocarbon aromatization technique in A petrochemical field. Fully exploit technology for the East petrochemical liquefied gas resources. Opened up a new way of production of triphen. It can solve the issue of materials. The processes used two stoves and four reactors, continuous operation. LGP without propylene after dehydrating, changing heat. Heated to certain temperature by raw materials heating furnace. Rezction of aromatization under the function of the particular catalyst. Reaction outcome direct separation, get product benzene, Toluene, Xylene and a few heavy aromatics.By many experiment and transformation, have established 100×10~4 t /a industrial demonstration installation. Through producing , practice and operating parameter are adjusted, grope a set of complete data. Production makes accepted product, reach design requirement. This project investment province. Comparing with catalytic reforming plant, it save investment eighty millions Yuan, production cost saves 2/3. This project go into operation not only large raising product added value, for enterprise, the economic benefits with good creation at the same time create favourable condition for that enterprise realizes chemical transition , have offered for domestic to build more large-scale similar installation to design basis.
