Hydrogen production from catalytic steam reforming of toluene over trace of Fe and Mn doping Ni/Attapulgite

Role of Mn in the Ni–Mn/SBA-15 Catalyst for Hydrogen Production by Biomass Steam Reforming at Relatively Low Temperature

“…In addition, Wang et al studied the performance of catalytic steam reforming of toluene on trace Fe- and Mn-doped Ni-based catalysts. The results indicated that the addition of trace amounts of Fe and Mn enhanced the toluene conversion, H 2 yield, and stability . Despite these earlier research studies, there was no report about the reaction mechanism of the steam reforming of biomass over the 9Ni–1Mn/SBA-15 catalyst.…”

“…The results indicated that the addition of trace amounts of Fe and Mn enhanced the toluene conversion, H 2 yield, and stability. 35 Despite these earlier research studies, there was no report about the reaction mechanism of the steam reforming of biomass over the 9Ni− 1Mn/SBA-15 catalyst. Therefore, in our recent research, the reaction mechanism in steam reforming of cyclohexane (C 6 H 12 ) as a tar model compound over 9Ni−1Mn/SBA-15 was studied using the transient method at 773 K. The findings suggested that the addition of a small quantity of Mn into Ni could improve the interaction between the surfaces of Mn and Ni, thereby potentially expediting the dehydrogenation of C 6 H 12 while impeding the dissociation of C−C bonds in the adsorbed hydrocarbons.…”

Recent Status in Catalyst Modification Strategies for Hydrogen Production from Ethanol Steam Reforming

“…The H 2 yield and catalytic stability are greatly improved over Ni 10 Fe 10 /MgAl 2 O 4 catalyst. Wang et al [304] reported that the addition of trace of Fe in Ni-based catalyst improving surface Ni 0 /Ni 2 + proportion and promoted the uniform dispersion of Ni species due to the cooperative effect, which inhibition of amorphous carbon and the growth of carbon nanotubes, improving the catalytic stability. Tian et al [305] prepared NiÀ Sn/CeO 2 catalyst with different Sn content from 0.25 to 2 wt.%, and the increase of Sn doping is conducive to the abatement of carbon deposition over NiÀ Sn/CeO 2 catalysts, but at the cost of lower ethanol conversion.…”

Hydrogen production from ethanol by steam reforming with recyclable NiCaOx/NaCl catalysts

“…Among the transition metal catalysts, Ni and Co catalysts have gained attention due to their comparable catalytic activity to noble metals in breaking C-C bonds, becoming a research hotspot in ethanol steam reforming. 8,[12][13][14][15][16][17][18] However, single transition metal catalysts are prone to sintering and carbon deposition. The addition of co-catalysts can enhance the dispersion and electronic structure of the active components, inhibiting catalyst sintering and slowing carbon deposition.…”
