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...

severe accidents of process industries in iran have increased significantly in recent decade. this study quantitatively analyzes the hazards of severe accidents imposed on people, equipment and building by a hydrogen production facility. a hazard identification method was applied. then a consequence simulation was carried out using phast 6.54 software package and at the end, consequence evaluat...

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...

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...

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...

Renewable hydrogen may be produced in the near term at a cost that is competitive with natural gas reforming by integrating hydrogen production with existing industrial utilization of agricultural residues. A team of government, industrial, and academic organizations is developing a steam reforming process to be demonstrated on the gaseous byproducts from a process for making activated carbon f...

This work was funded by the Hydrogen Program Office of the U.S. Department of Energy under Grant No. DE-FG01-99EE35099 and represents the second task of three to be completed under this contract. The first task presented a broad overview of the costs for creating infrastructures to supply direct hydrogen, methanol, and gasoline to support fuel cell vehicles (FCV’s). A conclusion of the report r...

In the present work, catalytic behavior of nickel-based catalysts supported on ceria/zirconia, undoped and doped with lanthanum neodymium (3.5Ni/Ce0.8La0.5Nd0.2Zr0.13O2−x), was investigated under different reactions: steam reforming, partial oxidation autothermal reforming fuels (methane, biogas, propane). The properties these were evaluated at a temperature 800 °C, atmospheric pressure, GSHV =...
