Catalytic steam reforming of bio-oil model compounds for hydrogen production over coal ash supported Ni catalyst

Hydrogen production from pyrolysis catalytic reforming of cellulose in the presence of K alkali metal

“…In addition, the addition of K might promote the reforming of hydrocarbons [24], which can contribute to the production of H2 through reforming reactions. And similar phenomenon was found by Wang et al [47,48], they studied the effect of alkali metal on the catalytic reforming of bio-oil.…”

Steam reforming of acetic acid over coal ash supported Fe and Ni catalysts

“…In our previous research, 15 wt% Ni/coal ash performed well in acetic acid steam reforming, and was comparable with conventional catalysts [26]. In this study, we investigate the functions of AAEMs and Fe-oxide in coal ash, and we develop inexpensive and efficient coal ash-supported catalysts for HOAc steam reforming.…”

“…In this reaction pathway, HOAc cannot be completely converted to gas, resulting in rather low carbon conversion and H 2 yields. During reaction over Al 2 O 3 , carbon conversion and H 2 yield greatly improve to 65.95% and to 30.60%, respectively, while CO 2 production rapidly decreases to 23 ) could act as the active metal in catalyzing the reforming reaction for hydrogen production, and AAEM oxides could serve as assistants for enhancing water adsorption [26]. Therefore, unlike reforming over quartz and Al 2 O 3 where ketonization is favored, HOAc would undergo decomposition to produce intermediates if reformed over Fe, and OH is generated by adsorption of H 2 O on AAEM oxides.…”

Hydrogen production from catalytic reforming of the aqueous fraction of pyrolysis bio-oil with modified Ni–Al catalysts

“…Although, noble metals e.g. Pt and Pd are confirmed to be highly active, nickel-based catalysts have also been extensively researched, since Ni has comparatively lower cost and Ni-based catalysts are effective for O-H and C-C cracking reactions [20][21][22]. In addition, Ni-based catalysts have been reported to have better performance in terms of hydrogen production and catalyst deactivation, compared with other metals such as Co, Fe and Cu, for the steam reforming of acetic acid [23].…”
