The influence of catalyst support alumina-silica in terms of different Al2O3 to SiO2 mole ratios containing 20 wt.% Ni on the production of hydrogen and catalyst coke formation from the pyrolysis-catalysis of waste tyres is reported. A two-stage reactor system was used with pyrolysis of the tyres followed by catalytic reaction. There was only a small difference in the total gas yield and hydrog...

The catalytic conversion of hydrocarbons for the production of hydrogen and syngas (H2/CO) is of great interest in research and technology. Detailed heterogeneous kinetics can also provide a better understanding of the reactions involved during the catalytic processes commonly used in the synthesis gas production. The developed models can predict conversion and selectivity at varying operation ...

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...

the bubble effectiveness in liquid phase cylohexane non-catalytic oxidation process is discussed in this paper. then the bubble effectiveness and a new proposed kinetic model are used in the mathematical model of the industrial reactor for the cyclohexane non-catalytic oxidation process. furthermore, simulation and optimization based on this reactor model are carried out. the results of simulat...

Aqueous-phase reforming (APR) can convert methanol and other oxygenated hydrocarbons to hydrogen carbon dioxide at lower temperatures when compared with the corresponding gas phase process. APR favours water-gas shift (WGS) reaction inhibits alkane formation; moreover, it is a simpler more energy efficient process gas-phase steam reforming. For example, Pt-based catalysts supported on al...

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...

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...
