Trireforming is a combination of methane steam reforming, CO2 dry reforming, and methane oxidation (Kang et al., 2007) that utilizes existing, unwanted CO2 produced from the conversion of natural gas to electricity and from natural gas to hydrogen.  This paper reports on the conversion of CO2-rich refinery effluents to syngas (CO and H2) using a novel nanoparticle Ni metal catalyst supported on a dynamic TiO2 anatase support.  The nanoparticles were formed and deposited onto the support using a reverse micelle approach.  The support and the metal work synergistically to catalyze CO2, H2O, and O2 dissociation reactions and oxidation of carbon bound to the Ni metal.  In situ FTIR spectroscopy was used to investigate the oxygen transport mechanism that exits within the support material. Results show active Ti3+, Ti4+, and Ni0 domains -- all within specific temperature ranges. Nanoparticles increase the intimate contact between the support and the nickel metal.
