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 ...

Boosting CO2 Selective Electroreduction to CH4 With High Efficiency Over Oxygen‐Riched Cu‐CeO2 Catalyst by Constructing Heterointerface Built‐in Electric Field

EcoEnergy, EarlyView.
Defect‐rich Cu‐CeO2 heterojunction generates a strong built‐in electric field, accelerates directional electron transfer from CeO2 to Cu, and enables highly selective and efficient CO2 electroreduction to CH4. ABSTRACT Electrochemical CO2 reduction reaction (CO2RR) to CH4 offers a sustainable route for carbon neutrality, but it is hindered by sluggish ...

EFFECTS OF MATERIAL CHARACTERISTICS ON PERFORMANCE OF HYDROCRACKING CATALYSTS

Journal of the Turkish Chemical Society Section B: Chemical Engineering, 2017
Hydrocracking is a refinery process used to convert heavy hydrocarbon fractions to lighter cuts with high added value. The products that usually range from heavy diesel to light naphtha involving middle distillate as targeted cut are obtained as a result

Conversion of Spent Transformer Oil Into H2‐Rich Syngas via Microwave‐Induced Steam Reforming Over Ni─Co Catalysts Supported on Fe‐Rich Diatomite

Advanced Energy and Sustainability Research, Volume 7, Issue 10, October 2026.
Spent transformer oil (STO) was converted to H2‐rich syngas by microwave‐induced steam reforming over Fe‐rich diatomite‐supported catalysts. Higher microwave power and steam‐to‐carbon ratio improved H2 production and carbon conversion, with 840 W and an S/C ratio of 3.6 giving the best results. 5%Ni5%Co/diatomite gave the highest H2 yield (98.80 mmol g−

Low‐Temperature in Situ Upgrading of Ultra‐Deep Heavy Oil Using Ni–Ce/MOF–OTf Superacid Catalysts to Enhance Energy Utilization and Sustainability

EcoEnergy, Volume 4, Issue 5, October 2026.
A triflate‐functionalized Ni–Ce/MOF–OTf superacid enables low‐temperature (∼140°C) in situ upgrading of ultra‐deep heavy oil. It reduces viscosity by 92.11% in 12 h, maintains activity over cycles, and delivers 90.25% recovery with a lower carbon footprint by selective bond cleavage. ABSTRACT Ultra‐deep heavy oil is an important unconventional resource,
