Abstract: Provided is a CO2 recovery device of an internal combustion engine capable of efficiently recovering CO2 emitted from an internal combustion engine or CO2 in the air, and of efficiently synthesizing methane using CO2. A CO2 recovery device of an internal combustion engine includes a CO2 capturing material disposed at a through channel of gas including CO2 to capture CO2 in the gas, and methanation catalyst to let CO2 desorbed from the CO2 capturing material react with H2 obtained from a H2 supply source to generate methane. The CO2 recovery device has a function to raise temperature of the CO2 capturing material using heat generated from the internal combustion engine to desorb CO2.
