Hydrogen production in fluidized bed by chemical-looping cycle

Kinetic Study of the Reduction Step for Chemical Looping Steam Methane Reforming by CeO2‐Fe2O3 Oxygen Carriers

“…For this purpose, CO is converted to CO 2 via the water‐gas shift (WGS) reaction that is carried out in two steps including high‐temperature shift (HTS) and low‐temperature shift (LTS). Thereafter, hydrogen is separated from CO 2 by methods such as pressure swing adsorption (PSA) , . Both, WGS and PSA, are energy‐consuming and require high capital investment .…”

Spinel Mixed Oxides for Chemical-Loop Reforming: From Solid State to Potential Application

“…p0235 Important aspects for the overall effectiveness of the process lie in the choice of operation conditions, appropriate reactor designs (fluidized bed [59][60][61]/moving bed [62]/fixed bed [63][64][65][66] reactors), and identification of suitable candidates to be used as corresponding oxygen carrier materials. s0100…”

Chemical looping for hydrogen production

“…Anyway, if the use of an inert material was desired, MgAl 2 O 4 or ZrO 2 have been proposed as candidates owing to their thermal and chemical stability (Kang et al, 2010). Jin et al (2007) found that Fe 2 O 3 /bentonite particles (60 wt% Fe 2 O 3 ) prepared by mechanical mixing were active for the water splitting reaction, but suffer from poor reactivity for fuel oxidation.
