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...

Characterization of Athabasca asphaltenes separated physically and chemically using small-angle X-ray scattering
DownloadFall 2010
Athabasca asphaltenes were characterized using small-angle X-ray scattering (SAXS) with synchrotron radiation. Two methods were used to separate asphaltenes from Athabasca bitumen. Conventional chemical separation by precipitation with n-pentane, and physical separation realized by passing...

Characterization of Centreline Segregation of Continuously Cast Microalloyed Pipeline Steel
DownloadSpring 2017
Quantitative electron microprobe analysis (EMPA) was used in this study to quantify the segregation of alloying elements (e.g., Mn, Si, etc.) at the centreline for continuous cast slabs and pipes of microalloyed steel exhibiting different Mannesmann Ratings. Elemental segregation levels at the...

Fall 2013
The high degree of variability of oil sands ores can be attributed to a mixture of different geological end members, i.e., estuarine sand, estuarine clay, marine sand and marine clay. This study focused on the mineralogy, especially of clay minerals, and toluene insoluble organic matter, referred...

Characterization of Clay Minerals in the Athabasca Oil Sands in Water Extraction and Nonaqueous Solvent Extraction Processes
DownloadFall 2011
Production of oil from the second largest oil deposit in the world, i.e., the Alberta oil sands containing approximately 13% of total proven oil reserves in the world (169.9 billion barrels), has been shown to be significantly influenced by clay minerals. Clay minerals in particular play a key...

Characterization of copper supported on titanosilicates for room temperature H2S adsorption
DownloadSpring 2012
Hydrogen sulfide (H2S) is a major contaminant of industrial gas streams. Amongst the various methods used for its removal, adsorption by metal oxides is the most promising. Copper oxide (CuO) is shown to have superior H2S removal capability at room temperature. H2S removal at room...

Characterization of Electroless Ni-P Coatings and Electrodeposition of Ni Coatings for Electrodes in Zinc-Air Flow Batteries
DownloadFall 2023
Electrochemical energy storage devices such as Li-ion or Zn-air batteries (ZABs) are utilized to store energy generated by renewable sources, since these sources are intermittent. Li-ion batteries uses flammable organic electrolytes (less safe than nonflammable aqueous electrolytes) and have high...
