Carbon Energy, EarlyView.This study employs a simple solid‐phase alkali‐oxygen oxidation (SAO) method to extract inherent components (humic acids) from coal. We successfully extracted yellow, brown, and black humic acids by adjusting the amount of alkali. Among them, brown humic acid extraction created abundant ultra‐micropores and closed pores, greatly enhancing sodium ...

Separation and Recovery of Bitumen from Oil Sand by CO2 Desorption of Amine Solution
Journal of MMIJBitumen extracted from oil sand has garnered increasing attention as an alternative energy source for fossil resources. Since oil sand consist of a mixture of bitumen (10-15 wt. %), water (4 wt. %), and sand (80 wt.

Impacts of refining Canadian partially upgraded bitumen: Fluid catalytic cracking
The Canadian Journal of Chemical Engineering, EarlyView.Abstract In this study, we examine the fluid catalytic cracking (FCC) performance of vacuum gas oil (VGO) from partially upgraded bitumen (PUB), a novel refinery feedstock from Canadian bitumen. FCC experiments were conducted in a lab‐scale FCC unit with VGOs from two different PUBs prepared using thermal cracking and solvent deasphalting, along with ...

Compositional Analysis of Bitumen and Bitumen-Derived Products [PDF]
Journal of Chromatographic Science, 1996 Th e America n Society for Testing Materials (ASTM ) procedures D2887 and D5307 are used for boiling range characterization of petroleum fractions up to 538°C (1000°F). Th e bitumens fro m the Uint a Basin (Utah ) contain approximatel y 60.0 wt % material boiling above 538°C (1000°F); hence, the AST M techniques leave major portions of the bitumens ...

Hydrogen donor‐assisted visbreaking of Canadian oil sands bitumen
The Canadian Journal of Chemical Engineering, EarlyView.Abstract High‐viscosity Canadian oil sands bitumen requires processing for efficient transportation and refining. Partial upgrading technologies, primarily based on thermal processing, can effectively reduce, or even eliminate, the use of costly diluent, increase bitumen quality and market value, potentially decrease greenhouse gas (GHG) emissions, and

World's fastest 10 000‐m breakthrough: The XY‐22 well redefines deep‐earth access in the Tarim Basin
Deep Underground Science and Engineering, EarlyView.The Tarim Basin in northwestern China hosts one of the world's deepest petroleum systems, exemplified by the XY‐22 ultra‐deep well (bottom depth: 11 116 m; ~220°C, ~145 MPa). This study integrates tectonic mapping, geological cross‐sections, ultraviolet fluorescence microscopy, and optical photothermal infrared (OPTIR) spectroscopy to characterize ...

Quantitative Insights into Atomic Scale Oil–Clay Adhesion Governing Shale Oil Retention and Mobility
ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.Atomic force microscopy reveals a clear adhesion hierarchy between shale oil and clay minerals, governed by nanoscale surface chemistry. Strong interactions on chlorite and illite arise from abundant polar sites and cation bridging, whereas weaker coupling on montmorillonite limits interfacial binding.
