Water is an essential element contributing to human life. Evidence shows that only a portion
of the water from sewage/tailings is recovered in the consolidated tailings process. The …

Abstract Treatment of petroleum-contaminated soil to a less toxic medium via physical and
chemical treatment is too costly and requires posttreatment. This review focuses on the …

Petroleum asphaltenes, a by-product of crude oil extraction, are a promising feedstock for
the development of high-value carbonaceous materials because of their high carbon content …

The refining process of petroleum crude oil generates asphaltenes, which poses
complicated problems during the production of cleaner fuels. Following refining …

Asphaltenes and resins remaining after heavy crude oil deasphalting (termed asphaltenes)
require rational utilization. Due to their surface activity, such utilization can consist in …

Construction of hierarchically porous carbon electrode materials is considered as an
efficient strategy for improving the performance of supercapacitors. Nevertheless, how to …

Crude oils are complex mixtures of organic molecules, of which asphaltenes are the
heaviest component. Asphaltene precipitation and deposition have been recognized to be a …

Solvent deasphalting of crude oil is an environmentally unfriendly and hazardous process
because of the volatility and explosiveness of the involved hydrocarbons (propane, butane …

The molecular structures of polycyclic aromatic hydrocarbons (PAHs) from different sources
(coal-derived asphaltenes (CA), petroleum-derived asphaltenes (PA) and soot (S)), that …

Nanotechnology is widely recognized for having important applications in many industries,
one of which is oil and gas. Both environmental and cost benefits can be achieved when …
