What type of coal is used in the plants that produce methanol from coal?
Thread Content
Hello, friends. I have a question. What type of coal is generally used for producing methanol from coal? Are medium-sized pieces purchased directly, or are small pieces or powder used? Should I use bituminous coal, lignite, or brown coal? I would be very grateful if those who are aware could share their thoughts.
Coal powder: only 90um-sized particles are fed into the gasification furnace for pulping
There is a coal slurry preparation process, and the gasification process equipment must be determined based on the quality of the coal
The type of coal used for coal-to-methanol production is determined by the gasification process employed; for example, pressurized fixed-bed gasification, atmospheric fluidized-bed gasification, and pressurized gas-flow bed gasification (using coal slurry or pulverized coal) all require different types and qualities of coal.
Yeah, I have another question: do you know which gasification process equipment is most commonly used in China these days?

Understood. May I ask again: do you know which gasification process is currently the mainstream in China? What are the main raw materials?
The mainstream gasification processes are: pressurized fixed-bed gasification (used by companies such as Datang Keqi and Xinjiang Guanghui), and pressurized fluidized-bed gasification (used by companies such as Shenhua Baotou and those in Xinjiang that use coal-water slurry furnaces, as well as Datang Dolun and Xinjiang Zhongneng Chemical Industry that use pulverized coal furnaces). It is difficult to determine the specific type of coal to be used; generally, the gasification technology is chosen based on the characteristics of the coal.
