Total methanation of syngas to synthetic natural gas over Ni catalyst in a micro-channel reactor

► Novel (micro-)channel reactor for methanation reaction from syngas to SNG. ► Metal-ceramics complex substrate: superior heat conduction and firm catalyst coating. ► Excellent reactor performance at 450-550 °C and 30 atm. ► Highly efficient reactor design with milliseconds contact time (e.g., 70,000 h−1).
