Simulation of co-production system based on coal partial gasification under different reactant gas atmospheres

In order to explore the comparison of coal partial gasification hydrogen-electricity cogeneration systems under different agent atmospheres, based gasification, including steam cycle power generation and syngas processing for hydrogen production, a hydrogen-electric co-production system its model semi-coke combustion are constructed, respectively using (H 2 O/O ) (CO /O as reactant gas. The effects oxygen-coal ratio carbon conversion on exergy efficiency composition reaction gas atmospheres were studied by Aspen Plus simulation. increases first then decreases with increase rate. Using has higher efficiency. changes little ratios, while overall content H , CO CH 4 in will rate, but growth rate continue decline.
