The use of a plasma reformer for the generation of hydrogen rich gas from diesel fuel has been investigated. A system that is normally used for investigating natural gas reforming has been modified in order to investigate the reforming of heavy liquid fuels. The composition of the reformate has been investigated as a function of the composition of the reagents. The use of a one-step reformer/wa...

This paper focuses on the comparison of different glycerol reforming technologies aimed to hydrogen and syngas production. The reactions of steam reforming, partial oxidation, autothermal reforming, dry reforming and supercritical water gasification were analyzed. For this, the Gibbs energy minimization approach was used in combination with the virial Equation of state. The validation of the mo...

This work initially focuses on developing a computational fluid dynamics (CFD) model of an industrialscale steam methane reforming reactor (reforming tube) used to produce hydrogen. Subsequently, we design and evaluate three different feedback control schemes to drive the area-weighted average hydrogen mole fraction measured at the reforming tube outlet ( x̄H outlet 2 ) to a desired set-point va...

Due to the feasibility of ethanol production in the United States, ethanol has become more attractive as a fuel source and a possible energy carrier within the hydrogen economy. Ethanol can be stored easily in liquid form, and can be internally pre-formed prior to usage in low temperature (200 o C – 400 o C) solid acid and polymer electrolyte membrane fuel cells. However, complete electrochemic...

The thermal valorization of glycerol to produce synthesis gas has been investigated under conventional and microwave heating systems. Different processes (pyrolysis, steam reforming and dry reforming) are compared, using a commercial activated carbon as catalyst. The reforming processes that employ oxidizing agents (CO2 or H2O) were found to promote higher glycerol conversions than mere termal ...

Experiments of propane and propene steam reforming have been performed over a Pd–Cu/c-Al2O3 catalyst and over a Ni/NiAl2O4 catalyst. Over the palladium-based catalyst, the steam reforming of propene is faster and more selective than steam reforming of propane. Over the Pd catalyst, the steam reforming of propane is likely inhibited by site poisoning. In contrast, over Ni-based catalyst the refo...

In an effort to estimate the feasibility of heat recuperation from internal combustion engine (ICE) by steam reforming (SR) or decomposition fuel, we study here required size a reformer exchanger in order power 3.7 kW engine. To that end, experimentally test transfer structured commercial reactor with ∼0.39 m2 area ∼1 L unit. We then simulate length for evaporation and several fuels, using publ...
