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...

Asphalt pavements are the most common type of pavements in North America. Increasing traffic demand, harsh weather conditions, and the tendency for infrastructure operators to reduce the cost (and, therefore, the frequency) of maintenance are the major reasons for asphalt performance improvement...

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...

Oil sands found in Athabasca and Cold Lake regions of Northern Alberta form Canada’s primary source of energy reserves. Asphaltenes, a significant part of bitumen is often considered to be the least valuable component of crude oil due to various factors such as difficulty in transporting and...

During the extraction of crude oil or bitumen, stable water-in-oil emulsions are inevitably formed. The emulsified water contains chloride ions and other organic acidic compounds that cause severe corrosion problems to the downstream plant equipment, creating operational and safety issues and...

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...

In this study, we describe the use of different silica materials to separate vanadium compounds from Asphaltenes. We used high performance flash chromatography separation method to separate asphaltenes at different solvent strengths on sea sand. The separation conditions were optimized for flow...

Microtubules are cellular structures that are crucial to many cellular functions including maintenance of cell shape, vesicular transport, and cell division. The dynamic instability of microtubules is the basic feature which enables them to do their cellular functions. Their pivotal role in cell...
