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 …
