This chapter reviews recent studies of catalytic reforming of logistic fuels at hightemperature. Aside from steam and autothermal reforming, special consideration is given to partial oxidation conditions. Natural gas, gasoline, diesel, and ethanol containing fuels are discussed. Methane and iso-octane as fuel surrogates are exemplarily used to explain the behavior of the reformers in particular...

The CO2 reforming of coke oven gas for the production of synthesis gas has been studied over an activated carbon, an in-lab prepared Ni/Al2O3 catalyst and physical mixtures of both materials in different proportions (AC+Ni) at 800 oC. It was found that there are two possible coexisting reaction pathways: the direct dry reforming of methane (decomposition of methane followed by gasification of t...

Plasmatron fuel converters have been investigated for the conversion of a wide range of fuels. This paper is a series of papers describing an experimental and computational study of plasmatron methane reformers. This paper presents a model that uses limited mixing and chemical kinetics to investigate the plasma assisted reforming of natural gas. The Partially Stirred Reactor (PaSR) model from t...

Air-blown gasification of biomass in fluidized bed reactors produces relatively low concentrations of hydrogen. The combination of a catalyst and calcium-based sorbent is being developed to increase the efficiency of converting producer gas from biomass gasification into hydrogen. The conversion process entails reforming the methane and tar, and converting carbon monoxide into hydrogen by the w...

An experimental and kinetic modeling study on the Ni-catalyzed conversion of methane under oxidative and reforming conditions is presented. The numerical model is based on a surface reaction mechanism consisting of 52 elementary-step like reactions with 14 surface and six gas-phase species. Reactions for the conversion of methane with oxygen, steam, and CO2 as well as methanation, water-gas shi...

As a favorably clean fuel, syngas (synthesis gas) production has been the focus of concern in past decades. Substantial literatures reported the syngas production by various catalytic reforming reactions particularly in methane or ethanol reforming. Among the developed catalysts in these reforming processes, Ni-based catalysts from hydrotalcite-like compounds (HTLcs) precursors have drawn consi...

In this study we developed LaNixAl1-xO3 perovskite systems using a sol-gelmethod (with propionic acid as solvent) to use in methane-reforming reactions for producing synthesis gas. To understand the roles of the nature of the precursor and calcination conditions on the formation of LaNixAl1-xO3, we carried out identifications using NMR, FT-IR, XRD, SEM, and TEM. The precursor struc...

At present, the commercial production of hydrogen is essentially carried out by catalytic steam reforming of hydrocarbons: natural gas and naphtha. However, the instability of the prices of natural gas makes the use of other raw materials increasingly attractive. This research focuses on the development of a technology for producing hydrogen from alternative resources, specifically from two typ...

Biodiesel’s contribution as a renewable energy carrier is increasing continuously. Fuel cell market penetration, although slow, is now an irreversible reality. The combination of solid oxide fuel cells (SOFC) with biodiesel offers considerable advantages because it entails both high energy conversion efficiency and nearzero atmospheric carbon emissions. This work is aimed at proving the efficie...
