A Preliminary Study on Pyrolysis and Gasification of Asphaltenes and Coal-Asphaltenes Slurry in Entrained Flow Reactor
DownloadFall 2012
The aim of this work is to study pyrolysis of coal-asphaltenes slurry in an atmospheric entrained flow reactor. Athabasca asphaltenes and Genesee coal, both from Alberta in Canada, were selected as the feedstock. Char characteristics and the structure of asphaltenes and slurry chars including...

Adsorptive Removal of CO2 by Amine Functionalized Sorbents: Experimental and Kinetics Study
DownloadFall 2012
Adsorption processes using functionalized ordered mesoprous silica sorbents have shown a great potential for post-combustion CO2 capture from flue gas. In this work an experimental and theoretical investigation was conducted on the adsorptive removal of CO2 onto amine functionalized mesoporous...

Fall 2012
Underground Coal Gasification (UCG) is a process in which coal is converted to syngas in-situ. UCG has gained popularity recently as it could be used to extract energy of deep-lying coal seams, and it reduces the footprints attributed to the gasification process. In this study, two models have...

MIXED METAL OXIDE AND MIXED METAL OXIDE SUPPORTED -ION EXCHANGED ZEOLITE SORBENTS FOR HOT GAS DESULFURIZATION
DownloadFall 2012
This study describes the evaluation of the mixed metal non-supported and supported ion exchanged sorbents for hot gas desulfurization capable of withstanding a wide temperature range and multiple sulfidation-regeneration cycles. Copper-cobalt, copper-cerium mixed metal oxide and mixed metal oxide...

Spring 2012
Modelling of solvent extraction was studied using 1,2,3,4–tetrahydronaphtalene (tetralin) and Poplar coal (lignite). A kinetic model was developed taking into account temperature, mass transfer limitations and dominating events (physical or chemical) during coal liquefaction. It was found there...
