Deoxygenation-enhanced chemical looping gasification: a new pathway to produce hydrogen from biomass

Abstract

Biomass-to-hydrogen production has been regarded as a potential approach for green hydrogen synthesize. However, the carbon dioxide and bio-tar are inevitably produced, which critically restricts the refinement of biomass-derived syngas....

Calcium carbide residue – a promising hidden source of hydrogen

“…Therefore, the search for alternative methods of hydrogen production is currently a hot topic. [10][11][12][13][14][15][16][17] Water splitting is a "green" opportunity to produce hydrogen [18][19][20] using electrochemical, [21][22][23][24] photochemical [25][26][27][28][29] and plasmolysis 10,30 methods (Fig. 1B).…”

Enhanced C2+selectivity in plasma-assisted chemical looping oxidative coupling of methane using (Na, Li, and K) doped LaMnO3

“…In the fuel reactor, oxygen carriers catalyse the activation and coupling of methane. In the air reactor, the oxygen carriers are oxidized by air to restore oxygen species, 23,24 which are recycled to the fuel reactor. 25,26 Oxygen carriers are a key factor in the CLOCM reaction.…”

Over 90% C2+ Selectivity in Kalium-Doped Manganese Perovskite Oxygen Carriers for Chemical Looping Oxidative Coupling of Methane with Plasma Assistance

“…10,11 In addition, the mixing of oxygen and methane poses a safety risk of explosion. 12 An air separation device must be provided at the end of a reactor to separate unreacted gaseous oxygen. There is an urgent need to develop a methane conversion pathway without gaseous oxygen.…”
