Coal Liquefaction Liquid Quality: Influence of Temperature and Heating Approach on Solvent Extraction of Coal
DownloadFall 2014
This project evaluated the impact of reaction temperature and of additional heating steps on the quality of the liquids obtained from solvent extraction of a lignite coal with tetralin. The points of focus were the coal liquid yield, physical properties, aromatic content and iron pyrite...

Colloid Science of Sand Remediation: A Study Motivated by the Non-Aqueous Extraction of Bitumen from Oil Sands
DownloadFall 2014
The current water-based method of bitumen extraction requires withdrawal of fresh water from the Athabasca River — a practice which leads to the continual buildup of tailings ponds and other environmental concerns. As Alberta’s bitumen production is expected to more than double by 2020, there is...

Comprehensive Study of the Bioconversion of Coal Using Laboratory Core Flooding Experiments
DownloadSpring 2014
Core flooding experiments were performed to understand in-situ coal bioconversion process. Subbituminous coal particles packed inside a biaxial core holder was inoculated with microbial culture and was continuously flooded with mineral salts medium and nitrogen rich nutrient solution....

Spring 2015
Previous studies on the extraction of liquid products from coals have focused mainly on increasing the yield, with very little emphasis on the quality of the liquid products. The main goal of this study is to achieve a balance between the yield and quality of the coal derived liquids. The first...
