Density, viscosity, and stability of products from combinations of visbreaking and deasphalting
The Canadian Journal of Chemical Engineering, EarlyView.Abstract Transporting bitumen through pipelines in Western Canada is cost intensive because the oil has to be diluted with light solvents to meet pipeline specifications. The diluent requirement can be reduced by visbreaking (VIS) and solvent deasphalting (SDA), each of which decrease the viscosity and density of the oil.

Microscopic details of asphaltenes aggregation onset during waterflooding [PDF]
, 2019 We report detailed microscopic studies of asphaltenes aggregation onset during waterflooding of petroleum reservoirs. To achieve this objective, a series of simulations are performed on asphaltenic-oil miscibilized with water at high pressure and temperature through molecular dynamics.

Four-component united-atom model of bitumen [PDF]
J. Chem. Phys. 138 (2013) 094508, 2013 We propose a four-component molecular model of bitumen. The model includes realistic chemical constituents and introduces a coarse-graining level that suppresses the highest frequency modes. Molecular dynamics simulations of the model are being carried out using Graphic-Processor-Units based software in time spans in order of microseconds, and this ...

Corn cob pyrolysis: A systematic literature review of methods and applications
The Canadian Journal of Chemical Engineering, EarlyView.Mapping the research landscape of corn cob pyrolysis. Abstractas The agricultural sector is experiencing a surge in waste generation due to population growth, creating an urgent need to convert byproducts into value‐added products. Maize (Zea mays L.), a leading global crop, produces significant byproducts, such as corn cob, which are often undervalued.
