Issues to consider when using high-sulfur coal in GE water-coal slurry gasification

Issues to be noted when using high-sulfur coal in GE coal-water slurry gasification.
One thing to pay attention to is the transformation process and the selection of catalysts; another is the corrosion resistance of the equipment. It is also necessary to consider the physical properties of hydrogen sulfide in order to ensure the stability of the Claus system. . . . . . . . . . . .
It mainly depends on whether it is inorganic sulfur or organic sulfur; a high content of organic sulfur can lead to the formation of carbonyl sulfide, and excessive accumulation of this substance in subsequent systems may cause explosions. For inorganic sulfur, using sulfur-resistant catalysts in the conversion system is sufficient.
Regarding water-coal slurry gasification, for the accompanying wide-temperature sulfur-tolerant complete conversion catalysts of the cobalt-molybdenum type, what is the maximum allowable sulfur content in the raw coal?
