PRODUCTION OF HYDROGEN BY WATER-GAS SHIFT REACTION ON Ru/C CATALYST

Production of fuel - cell grade hydrogen by sorption enhanced water gas shift reaction using Pd / Ni - Co catalyst

It has been demonstrated both thermodynamically and experimentally that fuel-cell grade hydrogen can be produced by a one-step sorption enhanced water gas shift (SEWGS) process at about 500 oC, where the water gas shift (WGS) catalyst and the CO2 sorbent are highly integrated. A synthetic CaO-based mixed oxide sorbent was also assessed, which showed a good CO2 capture capacity and stability in ...

Title: STUDIES OF HYDROGEN PRODUCTION BY THE WATER GAS SHIFT REACTION

Dynamic Model For Production of Biohydrogen Via Water- Gas Shift Reaction (RESEARCH NOTE)

In design of anaerobic bioreactor, rate equation is commonly used. Mathematical model was developed at steady state condition, to project concentration of gaseous substrate and product in biological oxidation of carbon monoxide with water to produce hydrogen and carbon dioxide. The concept of bioconversion was based on transport of CO from gas phase to liquid phase, as the CO consumption was in...

Hydrogen-Rich Gas Production from Steam Gasification of Biomass using CaO and a Fe-Cr Water-Gas Shift Catalyst

The technical feasibility of using calcium oxide (CaO) as a sorbent for CO2 and Fe-Cr as a catalyst for the water-gas shift (WGS) reaction using syngas for the steam gasification of biomass was investigated. The effects of temperature, steam to biomass mass ratio, CaO to biomass molar ratio, and Fe-Cr WGS catalyst on gas composition were studied. Within a temperature range of 250 C to 550 C, ...

Bioreactor Scale-up for Water-Gas Shift Reaction

A scale-up study has been performed with three different size reactors to establish the optimum operating conditions for the hydrogen production from synthesis gas by biological water-gas shift reaction using the photosynthetic bacterium Rhodosprilliunt rubrum. Optimum medium composition and operating conditions previously determined in a bench scale 1.25 L continuous stirred tank reactor (CSTR...
