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...

Ni0.9Fe0.1 alloy-supported solid oxide fuel cells with NiTiO3 (NTO) infiltrated into the cell support from 0 to 4 wt.% are prepared and investigated for CH4 steam reforming activity and electrochemical performance. The infiltrated NiTiO3 is reduced to TiO2-supported Ni particles in H2 at 650 °C. The reforming activity of the Ni0.9Fe0.1-support is increased by the presence of the TiO2-supported ...

Introduction Steam reforming is a process that converts hydrocarbon fuels into hydrogen and oxygenated carbon species. This process is important for catalytic hydrogen production and for direct electrochemical reforming of hydrocarbons over high temperature fuel cells, such as Solid Oxide Fuel Cells (SOFCs). One of the main problems associated with the process is that conventional reforming (el...

In the title compound, C(11)H(11)NOS(2), the benzine ring is coplanar with the thia-zole ring, making a dihedral angle of 0.81 (1)°. In the crystal, adjacent mol-ecules are connected into a helical chain along the b axis by S⋯S contacts [3.4345 (18) Å]. These helical chains are further assembled into a three-dimensional supermolecular network by inter-molecular C-H⋯O hydrogen bond between aroma...

Hydrogen is the most environmentally friendly fuel and can be efficiently used for stationary power and mobile applications. When burned or oxidized, it generates water as the only emission (small amounts of NOx are generated during the combustion process but can be controlled to very low levels). At present, hydrogen is produced almost entirely from fossil fuels such as natural gas, naphtha, a...

whereas American industry has available large supplies of natural gas; the refiner in the U.S.A. can therefore produce high quality fuels partly by catalytic cracking of heavy distillates, but his European counterpart has no such opportunity and must rely to a much greater extent on catalytic reforming processes to produce high quality fuels from straightrun naphthas. Again, while demand for hi...

The reforming of pure ethanol was studied over a bi-metallic precious metal (Rh/Pt) catalyst deposited on a ceramic monolith in order to analyze reforming process conditions. High ethanol conversion tests performed at low space velocities (<20,000 h ) confirmed that the catalyst could achieve 100% ethanol conversion to equilibrium concentrations of H2, CO, CO2 and CH4. Low conversion tests at h...

The CO2 reforming of coke oven gases (COG) was carried out over a Ni/γAl2O3 catalyst in order to obtain a suitable syngas for methanol synthesis. The influence of different operating conditions, such as temperature and volumetric hourly space velocity (VHSV), was studied. It was found that the H2 present in the feed gas promotes the Reverse Water Gas Shift reaction (RWGS), which produces water....
