AI Technical Summary
Technical Problem
Existing syngas production methods are energy-intensive and generate large amounts of pollutants and greenhouse gases, necessitating a more energy-efficient and environmentally friendly production method.
Method used
A combined system of molten carbonate fuel cell (MCFC) and solid oxide electrolyzer (SOEC) is used to produce carbon monoxide and hydrogen by electrolyzing carbon dioxide and steam in flue gas. The synthesis gas generation process is optimized by combining a methanation reactor and a gasifier.
Benefits of technology
It reduces energy consumption and pollutant emissions, providing a more environmentally friendly method for producing syngas that can efficiently generate carbon monoxide and hydrogen.

Abstract
A syngas generation system including a molten carbonate fuel cell (MCFC) including an MCFC cathode configured to receive an MCFC cathode input stream including a flue gas stream and an MCFC anode configured to output an MCFC anode exhaust stream including carbon dioxide and steam. The syngas generation system further includes a solid oxide electrolysis cell (SOEC) including a SOEC cathode and a SOEC anode. The SOEC is configured to receive a SOEC cathode input stream at the SOEC cathode, the SOEC cathode input stream including at least a portion of the MCFC anode exhaust stream, co-electrolyze carbon dioxide and steam in the SOEC cathode input stream, and output a SOEC cathode exhaust stream including carbon monoxide and hydrogen gas from the SOEC cathode.
