CFD based optimization of Water Gas Shift Membrane Reactor

In the Hydrogen based economy, distributed power generation systems using fuel cell technology require modularity. This modularity in power generation can be achieved by process intensification of the equipments involved. The water gas shift reaction is an integral part of hydrocarbon based Hydrogen generation and the reaction is kinetically limited and hence occupies the largest volume. Proces...

Modeling and Simulation of Water Gas Shift Reactor: An Industrial Case

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...

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 ...
