A fundamental understanding of the stability of water-in-bitumen emulsions stabilized by surface active agents requires a good description of the molecular interactions between the different materials in contact. Of these surface active agents, asphaltenes and oil contaminated fine solids are...

Mercury is an air pollutant emitted from coal fired power plants. Once released into the environment, mercury undergoes conversion to organomercury compounds, which cause health concerns for both humans and animals. Many studies have been completed with the goal of reducing mercury emissions...

Solid oxide fuel cells (SOFC) can be fuelled with external-reformed natural gas or directly with raw natural gas which usually contains significant amount of H2S to reduce the system complexity. The anode catalyst as well as the current collector employed in those environments must have excellent...

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...

Hydrotreating is the response to the necessity of a cleaner feed for downstream processes and reduced pollution. Hydrotreating catalysts are vital in this process; hence catalyst deactivation is a key issue. The principal objective of this research was the experimental study of hydrotreating...

In this study, the effect of three polymer flocculants, polyacrylamide (PAM), Magnafloc 1011 (MF) and Al(OH)3-polyacrylamide (Al-PAM), on the settling of mineral freshwater and saline tailings was investigated. The settling of tailings significantly depends on solution salinity, polymer...

One of the central puzzles concerning the interaction of low Reynolds number (Re<<1) fluid transport with bacterial biomass is the formation of filamentous structures called bacterial streamer. Bacterial streamers can be tethered at one or both ends to solid surfaces, while the rest of the...

Canada has the world’s largest oilsands reserves. Part of the reserves is being considered as marginal and is not profitable to recover using current technology. Autoxidation (oxidation with air) is a potential upgrading strategy to produce more valuable products from the oilsands derived bitumen...

Bone defects are treated with bone grafts, replacing damaged or diseased bone tissue with either natural bone or bone substitutes. Synthetic graft materials, particularly bioactive glasses, have been developed to overcome the immunological and structural limitations of natural bone grafts....
