Carbon deposition following thermal methane decomposition under dry and steam reforming conditions has been studied on yttria-stabilized zirconia (YSZ), Y2O3, and ZrO2 by a range of different chemical, structural, and spectroscopic characterization techniques, including aberration-corrected electron microscopy, Raman spectroscopy, electric impedance spectroscopy, and volumetric adsorption techn...

Due to energy and environmental issues, hydrogen has become a more attractive clean fuel. Furthermore, there is high interest in producing hydrogen from biomass with a view to sustainability. The thermochemical process for hydrogen production, i.e. gasification, is the focus of this work. This paper discusses the mathematical modeling of hydrogen production process via biomass steam gasificatio...

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...

For the new process of effective utilization of energy, chemical recuperation of low-grade exhaust heat by steam reforming of dimethyl ether (DME) was proposed. Steam reforming of DME is an endothermic reaction as; DME + 3H2O + 122[kJ/mol] → 6H2 + 2CO2. If this reaction could be proceed by exhaust heat below 573 [K], those exhaust heat which is wasted to ambient would be recuperated as the fuel...

Producing both hydrogen and high-value carbon nanotubes (CNTs) derived from waste plastics is reported here using a pyrolysis-reforming technology comprising a two-stage reaction system, in the presence of steam and a Ni-Mn-Al catalyst. The waste plastics consisted of plastics from a motor oil container (MOC), commercial waste high density polyethylene (HDPE) and regranulated HDPE waste contain...

Introduction The steam reforming of alcohols, particularly methanol and ethanol, presents a promising method of producing hydrogen. Due to its high activity at relatively low temperatures, Pd/ZnO has received attention as a methanol steam reforming (MSR) catalyst to produce H2 at very high CO2 selectivity. 1 Pd supported on most other materials dehydrogenates methanol to CO. Similarly, Co catal...

Introduction Fuel cells, which produce electricity directly from hydrogen and oxygen, offer a clean and efficient potential alternative to internal combustion engines for generating power for portable and transportation applications. However, there currently is no infrastructure for the wide scale production and distribution of hydrogen to the transportation market. Instead of building new infr...
