We build our cities from stone, brick, steel, concrete, glass and bitumen – all derived from nature.
Bitumen is derived from oil, which means its price has risen over the past decade alongside that of crude oil.
In other words, 62% of the total sulfur content of oilsands derived bitumen is aromatic and 38% is aliphatic (Brons and Yu 1995).
Heavy oil and oil sands derived bitumen has been tested at various conditions to analyze the physical and chemical changes after autoxidation.
In contrast, the progressive radiolytic alteration of bitumens proposed to have derived from the radiolytic polymerisation of methane into an organic solid produces, upon pyrolysis, PAH of increasing average size and degree of alkylation.
For example, in Canadian oilsand-derived bitumen the asphaltenes fraction represents more than 10 wt% of the total bitumen [5], often close to 15 wt%.
The formation of gums and sediments are more when oxidizing oil sands-derived bitumen compared with lighter oil fractions (Bolshakov 2007).
The size and settling velocity of oil-mineral aggregates (OMAs) derived from diluted bitumen are primary constituents in predictive models for evaluating the potential fate of oil spilled in the aquatic environment.
The hydrodenitrogenation (HDN) and hydrodesulfurization (HDS) activities of these P promoted NiMo/γ-Al2O3 carbide catalysts were performed in trickle bed reactor using light gas oil (LGO) derived from Athabasca bitumen and model feed containing quinoline and dibenzothiophene at industrial conditions.
We derived exposure estimates for bitumen fume and condensate, organic vapor, and polycyclic aromatic hydrocarbons, as well as for asbestos, crystalline silica, diesel motor exhaust, and coal tar.
