This decommissioned ERA site remains active temporarily to support our final migration steps to https://ualberta.scholaris.ca, ERA's new home. All new collections and items, including Spring 2025 theses, are at that site. For assistance, please contact erahelp@ualberta.ca.
Theses and Dissertations
This collection contains theses and dissertations of graduate students of the University of Alberta. The collection contains a very large number of theses electronically available that were granted from 1947 to 2009, 90% of theses granted from 2009-2014, and 100% of theses granted from April 2014 to the present (as long as the theses are not under temporary embargo by agreement with the Faculty of Graduate and Postdoctoral Studies). IMPORTANT NOTE: To conduct a comprehensive search of all UofA theses granted and in University of Alberta Libraries collections, search the library catalogue at www.library.ualberta.ca - you may search by Author, Title, Keyword, or search by Department.
To retrieve all theses and dissertations associated with a specific department from the library catalogue, choose 'Advanced' and keyword search "university of alberta dept of english" OR "university of alberta department of english" (for example). Past graduates who wish to have their thesis or dissertation added to this collection can contact us at erahelp@ualberta.ca.

EFFECT OF SOLVENT DEASPHALTING PROCESS ON THE PROPERTIES OF DEASPHALTED OIL AND ASPHALTENES FROM BITUMEN
DownloadFall 2017
Asphaltenes are a solubility class of bitumen known to have undesirable properties. As asphaltenes are insoluble in paraffinic solvents, they can be separated from bitumen by adding a solvent such as n-pentane or n-heptane to produce better quality deasphalted oil (DAO). This process is called...

Hydrothermal Treatment of Bitumen Froth at 250 °C: Impact on Bitumen Properties and Role of Clay Minerals
DownloadFall 2023
Bitumen froth produced in the hot water extraction process of mined oil sands consists of about 60 wt % bitumen, 30 wt% water and 10 wt% mineral solids. To convert the bitumen in bitumen froth into a marketable product, the water and solids need to be separated. Solvent-based froth treatment...
