Effect of Ni Particle Location within the Mesoporous MCM-41 Support for Hydrogen Production from the Catalytic Gasification of Biomass

Abstract: Thermal processing of biomass in the presence of a catalyst is a promising technology to generate H 2 -rich gases for fuelling the future. Metal particles loaded on porous supports have been widely used for biomass gasification. However, no detailed research has been designed for describing the catalytic performance of nickel particles located inside compared to outside the pores of the supports. In this work, two groups of Ni/MCM-41 catalysts were prepared: Iseries catalysts where most of the NiO particles we… Show more

“…Ni sample presents a relevant second reduction process at higher temperature that was attributed in the literature to the reduction of NiO species with relative lower size 44 . However, it has to be pointed out that ~46% of Ni species were estimated to be reduced for all samples during pretreatment at 470ºC.…”

“…For a better Ni dispersion, various nano-porous supports such as MCM-41 [23,24], zeolite [25], and SBA-15 [26,27] have been utilized to confine the size of Ni nano-particles inside the pores of the catalyst support. This type of confined reaction space with uniform Ni particles could enhance the production of H 2 -enriched syngas.…”
