Hydrogen generation technologies have become increasingly important due to recent attention focusing on fuel cells. The water-gas shift reaction, which is performed in two stages as highand low-temperature shift, is of central significance to produce highpurity hydrogen. Generally, the high-temperature water-gas shift reaction (HTS) is conducted on Fe-Cr catalysts. However, these catalytic syst...

Sequential Monte Carlo and quantum mechanical calculations of the electronic polarization of the ground and first vertical excited states of 1H-benzotriazole in water are made. Using statistically uncorrelated configurations and CASSCF ab initio calculations the increase in the ground and excited state dipole moments of 1Hbenzotriazole from gas phase to aqueous environment are obtained as 2.89 ...

In this research the performance of a fluidized bed membrane reactor for high temperature water gas shift and its long term stability was investigated to provide a proof-of-concept of the new system at lab scale. A demonstration unit with a capacity of 1 Nm³/h of ultra-pure H₂ was designed, built and operated over 900 h of continuous work. Firstly, the performance of the membranes were investig...

A Raman spectrometer extensively modified for deep ocean use was used to measure synthetic hydrates formed in an ocean environment. This was the first time hydrates formed in the ocean have been measured in situ using Raman spectroscopy. Gas hydrates were formed in situ in the Monterey Bay by pressurizing a Pyrex cell with various gas mixtures. Raman spectra were obtained for sI methane hydrate...

CO hydrogenation and oxidation were conducted over Ir supported on TiO2 ZrO2 catalysts using a feed mimicking the water–gas shift reformate stream. The influence of support interaction with catalysts’ redox chemisorption properties activity selectivity evaluated. Both oxidised to CO2 in absence H2, conversion 70% was obtained at 200 °C. For presence H2 these catalysts, favoured due spillover oc...

Using ambient pressure X-ray photoelectron spectroscopy (APXPS) and mass spectrometry (MS) while varying the temperature, we were able to directly understand how sequence of exposing reactant gases, CO2 H2, influenced surface species reverse water–gas shift reaction product formation on Ni(100). When first dosing at room temperature (RT), Ni(100) shows a significant amount oxide due spontaneous...

Landfill Gas to Energy This research investigates the utilization of landfill gas, an abundant waste product, by reforming it to syngas that can be converted to liquid fuels using Fischer Tropsch or to a H2 rich stream using water-gas shift. 65% of the 413 million tons of municipal solid waste (MSW) generated per year in the United States is landfilled, and 67% of the landfilled MSW is composed...

a synthesis of well logs was carried out and drilling mud weight data were analyzed to figure outanomalous high fluid pressure within the triassic evaporitic cap rock (the dashtak formation) andstudy its impact on the geometry of anticlinal traps in the gas rich gavbandi province located in thesoutheast part of the zagros mountains. the results indicated that the location of anticlinal traps at...
