Asphaltenes, defined as the fraction of crude oil soluble in toluene and insoluble in C5 to C7 paraffinic solvents, constitute the lowest value fraction of heavy oil. Sulfur is the most abundant heteroatom in asphaltenes. The present work explores two approaches for upgrading asphaltenes using...

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...

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...

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...

Adsorption of asphaltenes at liquid-liquid and solid-liquid interfaces is an undesirable phenomenon and considered to be the major contributor to several complications found in petroleum industry. Although the adsorption of asphaltenes on mineral surfaces has been extensively studied, little work...

Hydrotreating is the response to the necessity of a cleaner feed for downstream processes and reduced pollution. Hydrotreating catalysts are vital in this process; hence catalyst deactivation is a key issue. The principal objective of this research was the experimental study of hydrotreating...

Spring 2013
Adsorption behavior of nitrogen, argon and oxygen on silver exchanged titanosilicate (Ag-ETS-10) were studied in this work. A low temperature gas chromatographic determination of relatively low concentration argon (<1%) was developed, which was applied to evaluate the production of argon free...
