As demand for fuel increases, new technologies that can convert heavy oil and bitumen into light fuels are needed. Natural zeolites have been proven to catalyze reactions that decrease molecular weight, density, nitrogen, and metals content as well as vacuum residue content when mixed with raw...

Oiling-out, also termed as liquid-liquid separation (LLPS), is a phenomenon well observed in cooling crystallization when the solution becomes cloudy due to the formation of a second liquid phase. One of the methods to control LLPS is solvent exchange where surface droplets are produce in bottom...

Bitumen partial upgrading technologies aim to produce a product that meets viscosity and density specifications for pipeline transport with little to no addition of diluents. Thermal cracking processes are attractive for partial upgrading since they result in an increase in the light fractions....

The nature and structure of asphaltene nanoaggregates are frequently the subject of debate and speculation in the literature. The continental asphaltene nano-aggregate model, characterized by the presence of alkyl chains on their surface, and the archipelago nano-aggregate model, characterized...

The impact of mixing on diluted bitumen de-watering is studied in two stages using a fractional factorial design of experiments. The first stage evaluates the relative effects of bulk demulsifier dosage, local maximum energy dissipation, and mixing time. The second stage of experiments evaluates...

Hydrocarbon-based liquid-crystal domains were observed in unreacted heavy fractions extracted from Athabasca bitumen and bitumen derived hydrocarbon resource fractions. Transfer of these organic crystalline domains to the water-rich phase during SAGD production is explored here because there...

Ternary mixtures comprising cyclohexane + polystyrene + silica nanoparticles were recently shown to exhibit a closed loop two-phase region comprising colloid-gas and colloid-liquid phases1. This two-phase region is surrounded by single-phase colloid-gas and colloid-liquid phase regions and there...

Recently, ZnS quantum dots have attracted a lot of attention since they can be a suitable alternative for cadmium-based quantum dots, which are known to be highly carcinogenic for living systems. Suitable optoelectronic properties and non-toxic nature of ZnS quantum dots capacitate exiting...
