In order to improve the thermal efficiency of coke-oven gas power generation, this work establishes electrochemical and thermodynamic models for a novel process of coke-oven gas fueled solid oxide fuel cell integrated with its anode off-gas recirculation and chemical looping combustion. It begins with a traditional process with all anode off-gas combusted with air in an after burner for heat recovery, which suffers from higher steam consumption, lower power generation, and higher CO2 emissions. Key operating parameters of the steam/COG ratio of steam methane reforming, fuel utilization factor and recycle ratio of solid oxide fuel cell, as well as oxygen carrier and air inputs of chemical looping combustion are thoroughly analyzed and optimized for power generation of the proposed process. The net electricity generation for the novel and traditional processes are 315.8 and 290.7 MW per 500.3 MW of coke-oven gas consumption, respectively. Moreover, the exergy efficiency is improved from 56.4% to 63.1% and about zero direct CO2 emissions is achieved in the novel process.
