Modified nickel-based catalysts for improved steam reforming of biomass tar: A critical review
نویسندگان
چکیده
Abstract The gasification of biomass produces a syngas that can be used for electricity generation and fuels/chemicals production. However, tar is generated along with the as by-product which causes problematic issues in end-use syngas, such blockages, plugging corrosion. Catalytic steam reforming suitable option to convert into more presence nickel-based catalysts, preferred catalyst, mainly due their activity low cost. There has been considerable research reported literature on modified catalysts reforming. These modifications have carried out order improve performance Ni-based reforming, terms catalyst stability activity. Such improvements are achieved by manipulating properties catalyst. This paper therefore presents critical assessment these available improved considered this review were categorised as: addition secondary metal (Fe, Co, Cu, Cr), noble metals (Pt, Pd, Rh, Au, Ir), rare earth promoters (Ce, La), alkali alkaline (Sr, Ba, Ca, Mg,Ba) modification support material. aims at understanding responsible comparison unmodified catalysts. will serve guide further improvement

Catalytic Steam Reforming of Toluene as a Model Compound of Biomass Gasification Tar Using Ni-CeO2/SBA-15 Catalysts
Nickel supported on SBA-15 doped with CeO2 catalysts (Ni-CeO2/SBA-15) was prepared, and used for steam reforming of toluene which was selected as a model compound of biomass gasification tar. A fixed-bed lab-scale set was designed and employed to evaluate the catalytic performances of the Ni-CeO2/SBA-15 catalysts. Experiments were performed to reveal the effects of several factors on the toluen...

Steam reforming of methanol can be considered as an attractive reaction aiming at hydrogen production for PEM fuel cells. Although Cu/Al-contained catalysts are considerably evaluated in this reaction, further evaluation is essential to evaluate the impact of some promoters like Pt in order to find a comprehensively optimized catalyst. Pt promoter is employed with different methods in this ...
متن کاملBiomass steam-reforming in a low throughput fluidized bed reactor
This work presents the results from biomass gasification tests in a low throughput fluidized bed membrane reactor (FBMR) and compares them with two-phase model predictions. The operating temperature was decreased to 550C, while an equimolar steam/cellulose ratio was used. The profiles of kinetics limitation and biomass conversion were analysed when a palladium (Pd) membrane for hydrogen separat...
