Fall 2019
During thermal cracking of bitumen, olefins are formed via free radical reactions and are mainly concentrated in the naphtha and distillate cut of the upgraded bitumen. Olefins are undesirable in the upgraded bitumen product because they are associated with equipment fouling. As a result, these...

Spring 2019
To meet the increasing energy demand, there is a growing interest in exploiting the unconventional hydrocarbon resources such as heavy oil, bitumen, and shale oil. Combined electromagnetic (EM) heating and solvent injection is recently proposed to enhance oil recovery. The EM heating, converting...

Comprehensive System-level Assessments of Non-combustion Products from Wastes and By-products of Oil Sands
DownloadFall 2024
Baritto Loreto, Miguel Leonardo
Non-combustion products, i.e., those not burned for energy production, have the potential to diversify and enhance the resilience of the oil sands industry in anticipation of reduced fuel demand due to the ongoing decarbonization of the economy. Despite the significance of this transition, there...

Design and Performance Evaluation of Road Base Courses Comprised of Asphalt Emulsion and Asphaltenes Derived from Alberta Oil sands
DownloadFall 2023
Stabilization of granular base course materials has proven to be an effective method for enhancing the performance of pavement structure. Among the various methods used in this field, asphalt emulsion stabilization stands out as a widely employed technique that offers several benefits, including...

Dynamic Interfacial Tensions and Dilatational Viscoelastic Properties of Asphaltenes at Oil/Water Interface at High Pressure and High Temperature Conditions
DownloadFall 2021
The dynamic interfacial tension and dilatational viscoelasticity behaviors of asphaltenes at oil/water interfaces were investigated by means of an oscillating droplet tensiometer. This oscillating droplet tensiometer was modified to handle temperature of 120 °C and pressure up to 700 kPa. For...

Fall 2019
Thermal cracking of heavy oils is important industrially in processes such as visbreaking, coking and residue hydroconversion. In these processes, residue conversion is limited by formation of heavy products. Heavy product formation also contributes to industrially relevant problems such as...

Fall 2019
Asphaltenes, defined as a solubility class, are soluble in toluene and insoluble in paraffinic solvents such as 𝐶5 and 𝐶7. Asphaltenes have high heteroatom and a low H/C ratio compared to bitumen’s other fractions. Moreover, they have a complex structure, high molecular weight, and high melting...

The Formation of New Asphaltenes during Visbreaking of Vacuum Residue Deasphalted Oil and the Storage Stability of Product from Visbreaking
DownloadSpring 2020
Mild thermal cracking by visbreaking emerged as an important partial upgrading technology for reducing the viscosity of Canadian oilsands bitumen to enable pipeline transport. Under typical visbreaking conditions, the conversion of bitumen is described by first-order kinetics, which forms the...
