A Molecular Dynamics Study of the Dissolution of Asphaltene Model Compounds in Supercritical Fluids
DownloadSpring 2011
The demand for a new solvent to treat oilsands was behind the purpose of this project; molecular dynamics simulation was used in this study. Supercritical water, supercritical carbon dioxide and other selected organic solvents in their supercritical state were studied. Meso-tetraphenyl porphyrin...

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...

Mining haul trucks are operated on different ground conditions subjected to adverse shock loading, creating the need to give more attention to the truck components like suspension, tire, and the operating ground. Extensive experimental research has been done on these components at scale. In...

Spring 2011
A Surface Forces Apparatus (SFA) was used in this study to investigate the fundamental surface forces in oil sand processing research. Asphaltene coated surfaces were chosen as the research topic due to the critical role of asphaltenes in oil sands processing, from bitumen extraction, froth...

Two alkyl-bridged aromatic compounds, with molecular weights of 899.70 g/mol and 1127.99 g/mol, were thermally cracked with 1-hexadecene, 1- octadecene, or trans-stilbene, in a batch microreactor at 375–430 °C for 15 to 45 min. The objective of the study was to investigate the kinetics of the...

Spring 2016
This work investigated different acid catalysts and olefinic alkylating agents for the alkylation of an industrial asphaltenes feed. The working hypothesis was that alkylation would change the solubility parameter and increase the H/C ratio of asphaltenes sufficiently to cause some asphaltenes...

Canada has the 7th largest road network in the world with a total of 1.13 million kilometers (40% paved and 60% unpaved). Rise in traffic volumes, increased vehicle axle loading, extremely low air temperatures and seasonal freeze-thaw cycles have resulted in decreased performance of the asphalt...

Fall 2012
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...

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...

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...
