TRI-REFORMING OF METHANE USING CO2-CONTAINING GASES OVER SUPPORTED METAL CATALYSTS FOR MORE EFFICIENT PRODUCTION OF INDUSTRIALLY USEFUL SYNGAS

摘要

The motivation for developing tri-reforming process concept was to make advantageous use of the various CO2-containing gases for producing industrially useful synthesis gas (syngas) with desired H2/CO ratios without pre-separation of CO2. Such gases include flue gas from fossil-fueled power plants, natural gas that contain CO2 in significant concentration, and bio-gas which contain nearly equal amounts of CO2 and CH4. Tri-reforming is a novel process concept that we initially proposed for effective conversion and utilization of CO2 in the flue gases from fossil fuel-based power plants [C.S. Song, Chemical Innovation, 2001, 31, 21-26]. The CO2, H2O, and O2 in the flue gas need not be pre-separated because they will be used as coreactants for tri-reforming of natural gas.
