Abstract

A novel process concept called tri-reforming is being proposed and explored in laboratory for effective conversion and utilization of CO2 in the flue gases from fossil fuel-based power plants in the 21st century. The CO2, H2O, and O2 in the waste flue gas need not be pre-separated because they will be used as co-reactants for tri-reforming of natural gas. The tri-reforming is a synergetic combination of CO2 reforming, and partial oxidation of natural gas. Various base-metal catalysts (Ni) and noble-metal catalysts (Pt) were prepared using different supports (Al2O3, CeO2, MgO, ZrO2, etc.) and evaluated for tri-reforming. The simultaneous oxy-CO2-steam reforming reactions in the tri-reforming process could produce industrially useful synthesis gas with desired H2/CO ratios (1.5-2). Tri-reforming could eliminate carbon formation, which is a serious problem encountered in CO2 reforming of methane. This is an abstract of a paper presented at the 227th ACS National Meeting (Anaheim, CA 3/28/2004-4/1/2004).
