Purified hydrogen from synthetic biogas by joint methane dry reforming and steam-iron process: Behaviour of metallic oxides and coke formation

Chemical looping for hydrogen production

“…They found that the use of NiO:Fe 2 O 3 /bentonite particles (30 wt% NiO:30 wt% Fe 2 O 3 ) improved the fuel conversion while stable water splitting reactivity was reached, but formation of NiFe 2 O 4 can reduce the potential for H 2 generation (Svoboda, Siewiorek, Baxter, Rogut, & Puncochar, 2007). Moreover, carbon deposition was observed during the reduction step for Fe 2 O 3 :NiO materials, likely due to the presence of Ni (Plou, Dur an, Herguido, & Peña, 2014). Moreover, carbon deposition was observed during the reduction step for Fe 2 O 3 :NiO materials, likely due to the presence of Ni (Plou, Dur an, Herguido, & Peña, 2014).…”

Progress in oxygen carrier development of methane-based chemical-looping reforming: A review

“…CLC can, in principle, work with any fuel as long as OC shows sufficient reactivity toward fuel. Up to date, CLC has been demonstrated with methane (CH 4 ) [9][10][11][12][13][14][15], synthesis gas (syngas, H 2 + CO) [16,17], biofuels [18,19] and even direct coal feeds [20,21].…”

Analysis of Two‐Step Solar Thermochemical Looping Reforming of Fe3O4 Redox Cycles for Synthesis Gas Production

“…Furthermore, the reactivity of Fe‐based oxygen carrier can be improved by mixing iron oxide with other materials . Thus, Fe‐based oxygen carrier is regarded as the most appropriate candidate for chemical looping synthesis gas production . In contrast to fossil fuel utilization, the use of CH 4 in the solar thermochemical process based on iron oxide redox cycle is regarded as a transition technology for the sustainable production of clean transportation fuels.…”
