Conversion Of Biomass Derived Tar In A Catalytic Post-Gasification Process, Floria Rojas Chaves

Electronic Thesis and Dissertation Repository

The present MESc thesis reports the performance of a fluidizable CeO₂ promoted Ni/γ-Al₂O₃ catalyst to be used in a post-gasification process for tar removal. The catalysts developed were prepared using the incipient wetness technique and characterized chemically and physically, using the following techniques: N₂ Adsorption-Desorption, XRD, NH₃ and CO₂ TPD, Pyridine-FTIR, H₂-TPR, and H₂-Pulse Chemisorption. The catalysts were tested in a fluidized CREC Riser Simulator, in the 500°C-550°C temperature range, within 5 s-10 s reaction times, using both steam and steam-H₂/CO₂ atmospheres.A 2-methoxy-4-methlyphenol (2M4MP) compound was …
