Study of Asphaltene Structure Precipitated from Oil Sands
Eurasian Chemico-Technological Journal, 2013 In the paper microscopic structure and physicochemical characteristics of asphaltenes were investigated. Asphaltene was precipitated from natural bitumen of oil sand of Munaily-Mola deposit using organic solvent of petroleum ether.

The Canadian Journal of Chemical Engineering, Volume 104, Issue 4, Page 2020-2032, April 2026.25 g of oil sands extracted by dynamic accelerated solvent extraction, yielding 177 mL of bitumen–toluene extract and clean dried solids in approximately 12 min. Abstract Determining the oil, water, and solids (OWS) contents of oil sand is essential to many aspects of the oil sands industry including mine planning, optimization of extraction processes,

Probing Mechanical Properties of Water-Crude Oil Interfaces and Colloidal Interactions of Petroleum Emulsions using Atomic Force Microscopy [PDF]
, 2017 Atomic force microscopy (AFM) is frequently used to elucidate complex interactions in emulsion systems. However, comparing results obtained with “model” planar surfaces to curved emulsion interfaces often proves unreliable, because droplet curvature can ...

The Canadian Journal of Chemical Engineering, Volume 104, Issue 4, Page 1727-1742, April 2026.Supercritical water deasphalting. Abstract The removal of sulphur from heavy fuel oil (HFO) is essential to address environmental concerns and comply with the stringent regulations imposed by the International Maritime Organization (IMO) in 2020. Previously, the acceptable limit for sulphur was 3.5 wt.%, but it was recently changed to 0.5 wt.%.

Food Science &Nutrition, Volume 14, Issue 4, April 2026.Schematic overview of the experimental workflow investigating the effects of LBPs on gut microbiota. ABSTRACT Wilson's disease (WD) is a rare autosomal recessive disorder characterized by impaired copper metabolism and progressive multi‐organ damage. Emerging evidence suggests that gut microbiota dysbiosis and reduced microbial fermentation capacity ...

Bitumen chemical modification by thiourea dioxide [PDF]
, 2011 This work evaluates a novel bitumen modification through the use of a chemical agent, thiourea dioxide, substance which has been traditionally used as a reducing agent. Thermogravimetric analysis demonstrated the formation of new chemical compounds, most

Journal of Petroleum Geology, Volume 49, Issue 2, Page 433-447, April 2026.ABSTRACT In the Recôncavo Basin, Northeast of Brazil, mud diapirs have been reported for decades, but their role within the basin's petroleum system remains poorly constrained. Here, we combine 2D seismic interpretation, field observations, and organic geochemical analyses of rocks and oil seeps to investigate the relationship between diapirism and ...

ENERGY &ENVIRONMENTAL MATERIALS, Volume 9, Issue 2, March 2026.Liquid coal tar (CT) is synthesized into hypercrosslinked polymers (HCPs) via the Friedel–Crafts alkylation, followed by oxidation‐carbonization to form disordered microporous carbon. The resulting CF2CT exhibits a high three‐electrode specific capacitance of 342 F g−1 at 1 A g−1, and the assembled symmetric supercapacitor illuminates a light sign ...
