What etherification catalyst is used to produce dimethyl ether?
Thread Content
The previous set used a reactor for the production of dimethyl ether from methanol; the inlet temperature of the reactor was 260°C and the pressure was 1.9 MPa, while the outlet temperature was 360°C. However, I don’t know much about the catalysts used for this etherification process. I would appreciate it if experts could advise me on what brand of catalyst to use, which manufacturer it should come from, and what the approximate price is
As far as I know, there are three: Sichuan Tianyi Southwest Branch, Dalian Rick, and Wuhan Colin. However, my units are all 50,000 tons in capacity.
It is recommended to use the Tianyi model; it is quite mature, and its operating conditions are relatively mild. I have worked on the dehydration of 50,000 tons and 100,000 tons of methanol to produce dimethyl ether.
Currently, the main manufacturers of dimethyl ether catalysts in China are Tianyi Technology and Chengdu Tiancheng Carbon One Chemical Co., Ltd. The price in Gongzhuling is around 40,000 yuan per ton. It is recommended to consider Tianyi and Tiancheng; basically, all dimethyl ether production facilities in China were built by these two companies, each with its own advantages. Tiancheng has lower steam consumption
