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 ...

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

EcoEnergy, EarlyView.
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,

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

Yield Prediction of Renewable Diesel From Hydrocracking Process as a Function of Pressure and Temperature Using Analytical Semi Empirical Model (ASEM)

E3S Web of Conferences, 2018
The development of renewable fuels from biomass is very rapid, and becomes the main alternative to replace petroleum-derived fuels that are limited in stock. There has been a lot of experiments to optimize the production of renewable diesel, but it takes

Insight of Elementary Steps on the Polyethylene and Polypropylene Co‐Pyrolysis

Carbon and Hydrogen, Volume 28, Issue 3, Page 383-392, September 2026.
Pyrolysis of PP initiates first, accelerating PE cracking via secondary radical transfer, leading to n‐hydrocarbon yield enhancement. Py–GC/MS and nanoreactor computation are in agreement on the elementary step proposal. ABSTRACT Pyrolysis with gas chromatography & mass spectrometry (Py–GC/MS) technique was employed to analyze the yield variation of ...
