The stability of the ether bond affects coal dissolution during direct coal liquefaction and aliphatic ethers are reportedly the most reactive of the oxygenate classes during liquefaction. Some ether compounds are also persistent to high temperature during coal pyrolysis. The thermolysis of ether...

Capture of carbon dioxide from flue gas using amine functionalized silica based adsorbents has shown great potential recently. Despite their stable performance, the full potential of these adsorbents has not been researched in greater depth. In this thesis, experimental study and simulation of a...

Underground coal gasification (UCG) is a process of ‘in-situ’ conversion of coal into gaseous products with usable heating value through combustion with oxygen/air and gasification with steam. From the economic and environmental point of view, UCG is a highly promising clean energy technology...

Steam Regeneration of Amine Impregnated Silica Based Sorbents for Post Combustion CO2 Capture
DownloadFall 2014
In this study, an experimental investigation of CO2 capture using amine functionalized mesoporous silica based sorbents was carried out. Polyethyleneimine (PEI) impregnated silica sorbents were synthesized and tested in TGA under different adsorption temperatures and partial pressures of CO2....

Pyrolysis of asphaltenes in an atmospheric entrained flow reactor: A study on gasification reactivity and properties of chars
DownloadFall 2014
Solvent deasphalting, followed by asphaltenes gasification, has been recommended as a favorable alternative to coker based upgrading processes. However, very limited work has been carried out on pyrolysis and gasification of asphaltenes, at entrained flow conditions. The present work aims at...

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...

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...

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...
