Autothermal reforming (ATR) of liquid hydrocarbon fuels over nickel-based catalysts produces an equilibrium-limited mixture of hydrogen-rich syngas that is suitable as feed for solid oxide fuel cells. Autothermal reforming involves exothermic partial oxidation as well as endothermic steam reforming...

Gas condensate reservoirs experience great losses in productivity as the reservoir pressure drops below the dew point pressure due to formation and accumulation of liquid condensate around the well bore and subsequent reduction of gas relative permeability. Several methods have been proposed to...

Temperature distribution in activated carbon bed during adsorption of nitrogen (model gas for hydrogen); experiment & mathematical model Agnieszka Truszkowska 1 , Christopher Loeb 1 , Richard Chahine 2 , Bruce Hardy 3 and Goran N. Jovanovic 1 1 Oregon State University, Department of Chemical,...

Refineries and petrochemical plants are leading segment of the entire chemical process industry. It was reported that the value of the product shipments by refineries in U.S. accounted for 9.32% of the entire manufacturing sector of the U.S. economy in 2007. On the other hand, air emissions from...

Hydrogen has been considered as an important alternative energy vector and a bridge to a sustainable energy future. Production of hydrogen efficiently and economically from renewable sources, however, remains a challenge. Among diversified hydrogen production technologies, steam reforming of...

Stone Savannah River National Laboratory, Aiken, SC 29808 The Defense Waste Processing Facility (DWPF) at the Savannah River Site vitrifies High Level Waste (...

Fischer Tropsch (FT) synthesis is a polymerization process where a CH X species is added to a growing aliphatic chain. There are several models of the catalytic chain propagation rate and the termination of the chain growth (e.g. Anderson – Schulz – Flory model). The exact methodology for the...

Due to the concerns of “global warming”, CO2 sequestration from steel industry are becoming more and more important for the environments FeCO3, one of component for steel, was selected to investigate in order to design suitable processing to sequestrate the CO2 at the steel plant. It was found that...

The food versus fuel debate is becoming increasingly controversial in the wake of the industrialization of eastern countries and the ever-growing population of the world. Sustainable and renewable feed stocks are being explored as energy sources in order to meet the increasing energy demand and...

This study reports the development of a Ni based oxygen carrier and the investigation of an Integrated Gasification (IG) and Combustion of solid biomass as a fuel for Chemical-Looping Combustion (CLC). The aim is to develop a highly reactive, stable and fluidizable oxygen carrier (OC): a cobalt (Co...
