Chemical looping hydrogen production with modified iron ore as oxygen carriers using biomass pyrolysis gas as fuel

Abstract

The chemical looping hydrogen (CLH) production was conducted in a fluidized bed reactor with the modified iron ore oxygen carriers (OCs) using simulated biomass pyrolysis gas (BPG) as fuel.

Effect of Supports on the Performance of La-Modified CoFe2O4 Oxygen Carriers in Chemical Looping Hydrogen Generation from Hydrogen-Rich Syngas

“…Carbon capture efficiency (η c , %) η normalc = V CO 2 V CO 2 + V CO + V CH 4 × 100 % The theoretical hydrogen yield ( V normalH 2 * , mL) V normalH 2 * = ( V CO 0 − V CO ) + ( V H 2 0 − V H 2 ) + 4 × ( V CH 4 0 − V CH 4 ) SR: …”

Efficient utilization of Al2O3 as structural promoter of Fe into 2 and 3 steps chemical looping hydrogen process: Pure H2 production from ethanol

“…The use of renewable reductants to produce green H2 has been already investigated by several authors. Xu et al [16] studied the feasibility to produce H2 from biomass pyrolysis gas in a fluidized bed reactor using modified iron ores as redox material. The results showed that the NiO-iron ore was the best material for hydrogen production leading to the highest hydrogen yields and purity (8.89 mmol/g and 99.02 %) with high cycle performance (10 consecutive cycles).…”
