Fall 2011
The fragmentation of large coal particles at high temperature is important to the efficient operation of Corex process of steelmaking, which uses raw coal instead of coke. The hypothesis is that the heterogeneity within coal particles affects the fragmentation. The interface of minerals and coal...

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...

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...

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...

Solvent extraction of coal: Influence of solvent chemical structure on extraction yield and product composition
DownloadSpring 2012
In recent years the need for new carbon sources to supplement crude oil for the production of fuels and chemicals, again focused on coal as suitable candidate. Old and new technologies are being developed to convert coal in valuable products. An old technology such as solvent extraction of coal...

Study of Bio-densification Process in Oil Sands Tailings: Modeling and Experimental Validation
DownloadFall 2012
Slow densification of mature fine tailings (MFT) is one of the major challenges in reduction of tailings inventory, pore-water recovery and reclamation of tailings for oil sands industry. Bio-densification is a new treatment method in which densification of tailings is accelerated through...

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...

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...

Fall 2013
This work is divided into two parts: (1) Synthesis of amine functionalized adsorbents using grafting technique for post-combustion CO2 capture, (2) Performance evaluation of structured bed configuration with straight gas flow channels using amine impregnated adsorbent for post-combustion CO2...
