Hydrogen-rich gas production from oxygen pressurized gasification of biomass using a Fe–Cr Water Gas Shift catalyst

Investigation of hydrogen production from model bio-syngas with high CO2 content by water-gas shift reaction

“…Aznar et al [12] investigated WGSR downstream the fluidized-bed biomass gasifier, reported that the profiles of H 2 O/CO ratio correlated well with the composition of final product gas. Maroño et al [13] tested the HTS performance of FeeCr catalyst downstream the oxygen pressurized gasifier, concluded that the increase of H 2 content in product gas strongly correlated to H 2 content of feeding gas, and space velocity can be adjusted to minimize the steam amount required.…”

Bio‐Hydrogen Production: Current Scenarios and Future Prospects

“…Under these conditions, hydrogen content in the syngas can reach values ranging from 35% to 45% vol. Maron ' o et al (2010) have studied the catalytic activity of a Fe-Cr WGC catalyst in terms of CO conversion and H 2 production [8]. The infl uence of the main operating parameters including feed composition, space velocity and steam to CO ratio, on the activity of the catalyst has been studied.…”

High-temperature Water–Gas Shift catalysts for hydrogen enrichment of a gas produced by biomass steam gasification

“…This configuration of the WGS catalyst supported on ceramic foam represents the innovative part of the study. The great influence of operating parameters, such as H 2 O/CO ratio and reaction temperature on sintering and coke formation during high-temperature Water-Gas Shift catalysts is reported in the literature [21,22]. The different iron/ CeO 2 /foam catalysts' efficiency and stability were studied versus preparation (iron and ceria contents) and operating parameters.…”
