Bitumen froth generated from water-based extraction of Alberta oil sands typically consists of 60 wt % bitumen, 30 wt % water, and 10 wt % mineral solids. The froth has to be cleaned by removing th...

Mineral particles encountered in oil production and many chemical processes are generally adsorbed with organics (e.g., bitumen), playing an important role in determining their wettability and interaction behaviors. In this work, the surface properti

The mature fine tailings (MFT) generated from oil sands operations in northern Alberta, Canada, is the most challenging mine tailings to dewater. The MFT forms a gel structure and takes decades to settle and release water. Dewatering of a MFT sample

The catalytic hydrodenitrogenation of heavy petroleum fractions is important for the production of high-quality fuels, because the nitrogen-bearing compounds poison acidic catalysts and inhibit sulfur removal. Two families of synthetic nitrogen-conta

The sorption of solvents in asphaltenes, residual bitumen, and organic matter is of interest in oil sands production and extraction. In this study, we investigate the sorption and desorption rates of cyclohexane in a thin film of asphaltene using a g

Cracking and coke formation of a series of pyrene-based model compounds were investigated by thermogravimetric analysis (TGA) and microreactor experiments. The structure of the model compounds is that of a three-island archipelago, consisting of two

We performed density functional theory (DFT) calculations using the WB97Xd functional with a dispersion correction term and the 6-31G(d,p) basis set to study the contributions of π–π stacking and hydrogen-bonding interactions to the aggregation o
