WebJul 23, 2003 · An industrial side-fired steam reformer in a hydrogen plant is simulated under dynamic conditions. A rigorous model with verified reaction kinetics is used. This model incorporates aspects of heat transfer in the furnace and diffusion inside the catalyst pellet. WebThe most common industrial method to make ultra-pure hydrogen is by steam-methane reforming (SMR) using a catalyst at the temperature 890-950° C. The reformed gas is then subjected to a high temperature water gas shift (WGS) reaction at 300-400°C. The WGS reactor effluent typically contains 70-80% H2, 15-25% CO2, 1-3% CO, 3-6% CH4, and trace ... ship of blood charles oldham https://akumacreative.com
