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 ...

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

Water‐based drilling fluids formulated with mature fine tailings

The Canadian Journal of Chemical Engineering, EarlyView.
Abstract Mature fine tailings (MFT) are persistent, highly stable colloidal suspensions generated as byproducts of bitumen extraction from oil sands. Given their environmental risks, identifying viable applications for MFT could reduce their accumulation while offsetting natural resource use.

Strategic Integration or Compliance Lag? Mapping Trends and Evolution of SBSC Through the Lens of the ESRS Framework

Corporate Social Responsibility and Environmental Management, EarlyView.
ABSTRACT The sustainability balanced scorecard (SBSC) has become an influential framework for integrating sustainability into strategic management. Despite its growing adoption, research remains fragmented, and insufficiently aligned with the sustainability regulatory frameworks.

A Fast and Highly Stable Aqueous Calcium‐Ion Battery for Sustainable Energy Storage

ChemSusChem, Volume 18, Issue 6, March 15, 2025.
Aqueous batteries provide a low‐cost, safer alternative to lithium‐ion batteries, but their viability is often limited by rapid electrode degradation. This study shows that replacing K+ with divalent Ca2+ ions in the electrolyte significantly boosts the stability of both copper hexacyanoferrate cathodes and polyimide anodes, enabling fast‐charging ...
