The mass and energy conversion of mixed alcohol and power cogeneration system based on black liquor gasification was simulated and analyzed. The corresponding recirculation ratios were determined, at which points the synthesis tail gas is capable of being used as fuel of gas turbine under the condition of different CO2 contents at reactor inlet. The influence of CO2 content on the performance of synthesis reactor, power generation, utilities consumption and total energy utilization efficiency was studied. Results show that the recirculation ratio increases with the decline of reactant CO2 content. Evaluated by total energy utilization efficiency and utilities consumption, the suitable value of reactant CO2 content is 1%.
