ABSTRACTAtomic force microscopy is employed to study the structural changes in the morphology and physical characteristics of asphaltene aggregates as a function of temperature. The exotic fractal structure obtained by evaporation-driven asphaltene aggregates shows an interesting dynamics for a large range of temperatures from 25°C to 80°C. The changes in the topography, surface potential and adhesion are unnoticeable until 70°C. However, a significant change in the dynamics and material properties is displayed in the range of 70°C - 80°C, during which the aspahltene aggregates acquire ‘liquid-like’ mobility and fuse together. This behaviour is attributed to the transition from the pure amorphous phase to a crystalline liquid phase which occurs at approximately 70°C as shown by using Differential Scanning Calorimetry (DSC). Additionally, the charged nature of asphaltenes and bitumen is also explored using kelvin probe microscopy. Such observations can lead to the development of a rational approach to the fundamental understanding of asphaltene aggregation dynamics and may help in devising novel techniques for the handling and separation of asphaltene aggregates using dielectrophoretic methods.

Solids Content

A simple and rapid method has been developed to measure the bitumen, water, and solids content of Athabasca oil sand samples in order to efficiently serve both plant operations and research needs. A solvent blend of 74% toluene and 26% isopropyl alcohol extracts both the bitumen and the water from the solids producing a homogeneous liquid phase. The bitumen is determined gravimetrically on an aliquot of this solution. A Karl Fischer titration is used to measure the water concentration. Solids are measured gravimetrically or can be reported by difference. Mass balances between 99.05 and 100.25% are achieved routinely.

Physical And Mechanical Characteristics

In the paper separation methods of organic part from oil sands were investigated at experimantally. For the determination of organic part (liquid fraction) of oil sands the extraction methods was used in Soxhlet apparatus by solvent. Thermal processing was carried out with a monotonic heating of oil sands from room temperature to 560 0C. As showing results, organic part of Beke oil sands studied by extraction method were 12.0 wt.%. Thermal processing results showed, that the organic part of Beke oil sands were 9.6 wt.%. Physical and mechanical characteristics of liquid fraction are established by standard methods.
