Density functional theory calculations are performed to provide a molecular-level understanding of the mechanism of mercury adsorption on sulfuric acid-impregnated carbonaceous surface. The carbonaceous surface is modeled by a nine-fused benzene ring in which its edge carbon atoms on the upper...

Recent research has shown that fly ash may catalyze the oxidation of elemental mercury and facilitate its removal. However, the nature of mercury-fly ash interaction is still unknown, and the mechanism of mercury retention in fly ash needs to be investigated more thoroughly. In this work, a fly...

The objective of this review is to analyze potential technologies and their baseline performance of producing hydrogen from catalytic steam reforming of biodiesel byproduct glycerol. High oxygen content and high impurity level of biodiesel byproduct glycerol, as well as the complex intermediates...

The purpose of this study was to obtain the characteristics of CO2 hydrate formation and dissociation by using different experimental modes and pressures with glass beads. From the experiments, it was found that hydrate forms rapidly in each cycle, especially at high pressure. Hydrate blockage...

The continuous high-purity hydrogen production by the enhanced-sorption chemical looping steam reforming of glycerol based on redox reactions integrated with in situ CO2 removal has been experimentally studied. The process was carried out by a flow of catalyst and sorbent mixture using two...

A detailed comparative study on thermodynamic and experimental analyses of glycerol reforming for hydrogen production has been conducted in terms of the effects of temperature, pressure, water to glycerol feed ratio, feeding reactants to inert gas ratio and feeding gas flow rate (residence...

The 1998 failure of Long-Term Capital Management (‘LTCM’), a very large and prominent Greenwich, Connecticut based hedge fund, is said to have nearly brought down the world financial system. Over the years, few financial debacles such as LTCM, have been so often written about or discussed...

This paper examines the effects of county-level urbanization and natural amenities on subjective well-being (SWB) in the U.S. SWB is measured using individual-level data from the Behavioral Risk Factor Surveillance System (BRFSS) which asks respondents to rate their overall life satisfaction....

The phenomenon of data loss always occurs in the analysis of large databases. Maintaining the stability of analysis results in the event of data loss is very important. In this paper, we used a segmentation approach to generate a synthetic signal that is randomly wiped from data according to the...

In this paper, we present a cost-sharing scheme for the concave facility location game by exploring the concavity structure. We show that it is cross-monotonic and competitive, and recovers 1/3 fraction of the total cost. Copyright Springer Science+Business Media, LLC. 2013
