China Drying News reported that the first toluene methanol methylation industrial plant in China has completed industrial operation tests. China has taken the lead in globally owning the proprietary technology of methylation of toluene and methanol. This is the message from Yangzi Petrochemical on the 9th. The success of the plant's industrial operation test indicates that Sinopec has become the first company in the world to possess the proprietary technology of methylation of toluene and methanol, opening up a new approach for combining and comprehensively utilizing petroleum resources and coal resources.
The device is provided by the Shanghai Institute of Petroleum and Chemical Technology and the proprietary catalyst, Luoyang Engineering Co., Ltd. undertakes the engineering design, and Yangzi Petrochemical Co., Ltd. is responsible for the installation of the device, preparation of the drive plan, and trial production of the feed. The industry believes that methanol as a coal chemical derivative products, the cost is relatively low, toluene methylation methylation technology contributed to the combination of coal chemical industry and petrochemicals, to achieve the high value-added applications of coal chemical products, is a highly economical and social Benefits of the new route of xylene production.
According to reports, toluene methylation methylation process is methanol as a methylation reagent, toluene can be efficiently converted to xylene. The device is based on Yangzi Petrochemical's original 200,000-ton/year toluene shape selective disproportionation device. It uses petroleum product toluene and coal chemical product methanol as raw materials to produce purified terephthalic acid (PTA) raw material xylene. product. The capacity of the device designed to process toluene is 200,000 tons/year, and it can produce 240,000 tons/year of high-quality mixed aromatic hydrocarbons. After commissioning, the production cost of paraxylene will be greatly reduced.
It is understood that with the expansion of domestic PTA plant capacity, the contradiction between paraxylene and PTA does not match up and down. The downstream PTA has excess capacity and the upstream paraxylene resource is in short supply.
Since the 70s of last century, many companies at home and abroad have carried out the research and development of methylation of toluene and methanol, and so far there have been no reports of commercial operation. Sinopec Shanghai Research Institute of Petroleum and Petrochemicals initiated an industry-side trial of toluene methylation technology in 2009. They have completed the development and design of industrial side-line tests and 200,000-ton/year process packages, and successfully developed high-performance toluene methylation catalysts, multi-bed reaction processes, wastewater treatment processes, thermal integration, and low-temperature heat utilization processes. We have applied for domestic and foreign patents covering catalytic materials, catalysts, and process technologies, and have met the international technical conditions for industrialization of toluene methylation technology.
