Two-stage gasification process simulation and optimization …

This process decouples the two steps, among them, coal pyrolysis converts the hydrogen in coal to H 2 to the maximum extent without being consumed, and char gasification causes the coke react with the water vapor in the gasification agent (C + H 2 O ↔ H 2 + CO) to generate H 2 and CO. Through cooperative matching of the two stages, …
