Hydrogen Production by a Steam-Reformer for Heavy Hydrocarbons

Design of Optimization-based Controllers Applied to an Ethanol Steam Reformer for Hydrogen Production

This paper focuses on the control of a low-temperature ethanol steam reformer for in-situ hydrogen production. For this purpose, three optimization-based control configurations are proposed, namely, a linear model-based predictive controller, a linear quadratic regulator with output error integral action and a cascade control combining the two previous configurations. In all cases, control obje...

2D Heat and Mass Transfer Modeling of Methane Steam Reforming for Hydrogen Production in a Compact Reformer

Compact reformers (CRs) are promising devices for efficient fuel processing. In CRs, a thin solid plate is sandwiched between two catalyst layers to enable efficient heat transfer from combustion duct to the reforming duct for fuel processing. In this study, a 2D heat and mass transfer model is developed to investigate the fundamental transport phenomenon and chemical reaction kinetics in a CR ...

Sustainable Hydrogen Production by Catalytic Bio-Ethanol Steam Reforming

Production of hydrogen by unmixed steam reforming of methane

Hydrogen production by sorption-enhanced steam reforming of glycerol.

Catalytic steam reforming of glycerol for H(2) production has been evaluated experimentally in a continuous flow fixed-bed reactor. The experiments were carried out under atmospheric pressure within a temperature range of 400-700 degrees C. A commercial Ni-based catalyst and a dolomite sorbent were used for the steam reforming reactions and in situ CO(2) removal. The product gases were measured...
