Impacts of refining Canadian partially upgraded bitumen: Fluid catalytic cracking

open access: yesThe 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 ...

Microwave‐assisted catalytic pyrolysis of textile wastes: Synergistic effects and product characteristics

open access: yesThe Canadian Journal of Chemical Engineering, EarlyView.
Abstract This study examines the microwave‐assisted catalytic pyrolysis (MACP) of individual and blended textiles (cotton, polyester, nylon 6) using ZnO and a ZnO/natural zeolite catalyst. In a custom‐built microwave reactor operated at 500°C, 1 kW power, and a 15‐min residence time, textile wastes were pyrolyzed.

Hydrogen donor‐assisted visbreaking of Canadian oil sands bitumen

open access: yesThe 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

Do Firms Disclose Financially Material ESG Risks? Evidence From Japanese Food and Beverage Firms Using a Text Match Pretrained Transformer

open access: yesCorporate Social Responsibility and Environmental Management, EarlyView.
ABSTRACT This study develops a financial materiality‐oriented measure of ESG disclosure and examines how sustainability disclosures respond to evolving regulatory frameworks. Focusing on listed food and beverage firms in Japan from 2020 to 2024, we apply the Text Match Pretrained Transformer (TMPT) to assess the semantic relevance between disclosures ...
