Hydrogen and electricity produced from coal will represent a significant share in the energy mix within the foreseeable future. Various novel processes are developed or currently under development for hydrogen and electricity production from coal derived syngas. The commercial coal to hydrogen and coal to electricity processes include the coal gasification-water gas shift process and integrated...

A series of different M/TiO2 catalysts are prepared, where M = Au, Pt, Pd and Ag, with a 0.2 wt% loading, tested for activity as photocatalysts the water gas shift reaction, WGSR, using continuous flow, phase reactor. For both thermal (dark) photocatalytic (UV irradiated) WGSR best catalyst/photocatalyst is Au/TiO2. The kinetics studied function reactor temperature, Au loading concentrations CO...

We provide a detailed thermodynamic and economic analysis of two novel alternatives to the “standard” Shell coal IGCC with CO2 capture. In the first, the syngas coolers are replaced by a “partial water quench” where the raw syngas stream is cooled and humidified via direct injection of hot water. This design is less costly, but also less efficient. The second approach retains syngas coolers but...

A combined and sequential use of Monte Carlo simulations and quantum mechanical calculations is made to analyze the spectral shift of the lowest pi-pi* transition of phenol in water. The solute polarization is included using electrostatic embedded calculations at the MP2/aug-cc-pVDZ level giving a dipole moment of 2.25 D, corresponding to an increase of 76% compared to the calculated gas-phase ...
