Catalyst performance in reforming of tar derived from biomass over noble metal catalysts

Abstract

An activity test in the reforming of tar derived from cedar biomass over M–CeO₂–SiO₂ (M = Rh, Pt, Pd, Ru, Ni) was carried out in a secondary fluidized catalyst bed at lower temperature range (823–923 K) than the conventional methods. We have measured the formation rate of CO, CO₂, CH₄, H₂, and the yield of coke deposited on the catalyst surface and the yield of char accumulated in the primary bed. It was found that Rh–CeO₂–SiO₂ exhibited much higher performance than other metal catalysts in terms of the activity of tar reforming, and the yield of gas and coke.
