Abstract:

Since the renewable resources made from biomass are convenient in transportation, abundant in reserves, easy to access and able to reduce the consumption of fuel wood, the development of efficient hydrogen production from steam reforming of biomass is important for the industrial application of green and clean fuels. The impregnation method was used to prepare four kinds of catalysts with nickel acetate, nickel nitrate, nickel chloride and nickel sulfate as precursors loaded on ZSM-5 molecular sieve carriers. The catalytic activity of the four catalysts in the catalytic reforming of pine sawdust biomass was investigated on a fixed bed reactor. The volume fraction of hydrogen in the syngas was analyzed, and the catalysts were characterized by XRD, NH3-TPD,H2-TPR and SEM. The results showed that nickel acetate demonstrated fairly active interactions with the carrier, and the nickel species uniformly dispersed on the surface of the catalyst, so as to reduce the aggregation and carbon deposition of particles. The Ni-AC catalyst was of the highest activity in the catalytic reforming of pine chips, and the volume fraction of hydrogen in the syngas reached 60.47%, while the Ni-S catalyst was of the lowest activity on the catalytic reforming of biomass. The study results can provide theoretical support for the efficient recycling of biomass resources.
