Atomistic Approach towards Sodium Citrate Role on Surface Properties of Silica and Clay Minerals
DownloadFall 2022
The use of sodium citrate as a secondary processing aid in combination with caustic significantly improved bitumen recovery, specifically in poor oil sands ores. The role of sodium citrate on wettability alteration of solid surfaces, benefiting bitumen liberation as well as improving bitumen...

Atomic Layer Deposition of Metal Oxides for the Preparation of High Performance Zn-Air Battery Electrodes
DownloadSpring 2020
As the world continues to implement renewable energy technologies such as wind and solar, comes the demand for grid scale energy storage. Zn-air batteries (ZABs) are a promising candidate for grid scale energy storage because of their high energy density, low cost, high safety, and low...

The self-association properties of two model compounds of asphaltene, 2,6-bis[2-(pyren-1-yl)ethyl]pyridine (PyPPy, C41H29N) and 2,6-bis[2-(phenanthren-9-yl)ethyl]pyridine (PhPPh, C37H29N), were studied in deuterated chloroform and deuterated methylene chloride. 1H NMR spectroscopy titration...

Asphaltenes, defined as the fraction of crude oil soluble in toluene and insoluble in C5 to C7 paraffinic solvents, constitute the lowest value fraction of heavy oil. Sulfur is the most abundant heteroatom in asphaltenes. The present work explores two approaches for upgrading asphaltenes using...

Canadian oilsands bitumen contains one of the highest amounts of asphaltenes (16-20 wt %) among all crude oils. Asphaltenes are the lowest value fraction of bitumen. It differs from the other fractions of bitumen because of its insolubility in paraffinic solvents. Asphaltenes are insoluble in...

Athabasca oil sands contain 8 to 14% bitumen and are recovered using surface mining or steam assisted gravity drainage (SAGD). During primary upgrading of bitumen, the vacuum residuum from the distillation column is sent to the solvent de-asphalting unit where a paraffinic solvent is used to...

This thesis explored the properties of asphaltene nano-aggregates in crude oil and toluene based solutions and fouling at process furnace temperatures, and the links between these two phenomena. The link between stability of asphaltenes at ambient conditions and fouling at the conditions of a...
