Characterization of asphaltene molecular structures by cracking under hydrogenation conditions and prediction of the viscosity reduction from visbreaking of heavy oils
DownloadSpring 2013
The chemical building blocks that comprise petroleum asphaltenes were determined by cracking samples under conditions that minimized alterations to aromatic and cycloalkyl groups. Hydrogenation conditions that used tetralin as hydrogen-donor solvent, with an iron-based catalyst, allowed...

Casing pipes used in sour service are prone to two forms of failure: hydrogen induced cracking (HIC) and sulfide stress cracking (SSC). The objective of this thesis is to investigate the resistance of L80 ERW and Seamless steel pipe, with five different chemical compositions, to both HIC and SSC....

Natural Zeolite Catalysts for the Integrated Cracking, Waterless Extraction and Upgrading of Oilsands Bitumen
DownloadSpring 2012
Canadian oilsands bitumen represents one of the largest petroleum reserves in the world, but extraction of that resource raises significant environmental, operational and quality-related challenges. Current extraction processes are water intensive, generating high volume tailings ponds that are...
