Owing to their high efficiency and energy density, miniaturized fuel cells are an attractive alternative to batteries in the mW-W power generation market for portable consumer and military electronic devices [cf. 1-3]. Hydrogen is being actively considered as a fuel for power generation. It can be supplied either by storage devices or its in-situ generation using reformers. However, safety and ...

An interesting application of agricultural renewable sources is the employment of ethanol for supplying Molten Carbonate Fuel Cells (MCFCs). For that purpose, ethanol has to be converted into hydrogen by a steam reforming process. MCFCs are particularly suitable for this kind of applications due to their high tolerability to the impurities which are contained into the reaction products and also...

Catalytic steam reforming of glycerol for H(2) production has been evaluated experimentally in a continuous flow fixed-bed reactor. The experiments were carried out under atmospheric pressure within a temperature range of 400-700 degrees C. A commercial Ni-based catalyst and a dolomite sorbent were used for the steam reforming reactions and in situ CO(2) removal. The product gases were measured...

High-power-density alcohol fuel cells can relieve many of the daunting challenges facing a hydrogen energy economy. Here, such fuel cells are achieved using CsH2PO4 as the electrolyte and integrating into the anode chamber a Cu-ZnO/Al2O3 methanol steam-reforming catalyst. The temperature of operation, 250°C, is matched both to the optimal value for fuel cell power output and for reforming. Peak...

In the title compound, C(9)H(7)NO(2)S(2), the benzine ring is essentially co-planar with the thia-zole ring, making a dihedral angle of 0.36 (7)°. In the crystal structure, mol-ecules are linked by inter-molecular O-H⋯N hydrogen bonds between the carb-oxy group and the thia-zole N atom into chains along [10]. The chains are assembled into a supermolecular layer structure by thia-zole ring S⋯S c...

The title compound pteleifolosin C, C(21)H(20)O(7), was isolated from the petroleum ether-soluble fraction of an indigenous Chinese tree Melicope pteleifolia (Rutaceae). The dihedral angle between the benzene rings is 2.7 (2)°. Intra-molecular O-H⋯O hydrogen bonds occur. In the crystal, mol-ecules are linked by inter-molecular O-H-O hydrogen bonds.

T HE PURSUIT OF A JUST SOCIETY involves carefully balancing two contradictory necessities with regard to the corporate sector. Since corporations are responsible for much of the wealth and many of the jobs in a modern economy, they must be nurtured. At the same time, however, even as the corporate sector is fostered, justice and fairness require that these firms not be permitted to exercise dis...

Blends of bitumen, clay, and quartz in water are obtained from the surface mining Athabasca Oil Sands. To facilitate its transportation through pipelines, this mixture is usually diluted with locally produced naphtha. As a result this, naphtha has to be recovered later, recovery unit (NRU). The NRU process complex one requires knowledge Vapour-Liquid-Liquid Equilibrium (VLLE) thermodynamics. pr...

The kinetic modeling of the hydrocracking a mixture polystyrene (PS) and vacuum gasoil (VGO) over PtPd/HY catalyst has been carried out. reactions have performed in batch reactor under following conditions: 380–420 °C; 80 bar; content PS feed, 10 wt%; catalyst/feed ratio, 0.1 mass; time, 30–300 min. Different reaction networks models studied, which evolution product distribution (unconverted PS...
