Catalytic Hot Gas Cleanup of Biomass Gasification Producer Gas via Steam Reforming Using Nickel-Supported Clay Minerals

Amongst the issues associated with commercialization of biomass gasification, presence tars has been one most difficult aspects to address. Tars are an impurity generated from gasifier and upon their condensation cause problems in downstream equipment including plugging, blockages, corrosion, major catalyst deactivation. These lead losses efficiency as well potential maintenance resulting damaged processing units. Therefore, removal is necessary order for effective operation a gasification facility production high-value fuel gas. The catalytic activity montmorillonite montmorillonite-supported nickel tar catalysts will be investigated this study. Ni-montmorillonite was prepared, characterized, tested laboratory-scale reactor its reforming using naphthalene model compound. Efficacy function content, reaction temperature, steam-to-carbon ratio, loading. results demonstrate that catalytically active removing naphthalene. had high towards via steam reforming, efficiencies greater than 99%. activation energy calculated assuming first-order kinetics found 84.5 kJ/mole accordance literature. Long-term tests were also conducted showed 95% maintained over 97-h test period. A little loss observed decrease 97% 95%. To investigate activity, characterization fresh used samples performed thermogravimetric analysis, transmission electron microscopy, X-ray diffraction, surface area analysis. attributed caused by sintering coke formation.
