Impacts of refining Canadian partially upgraded bitumen: Fluid catalytic cracking
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 ...

Experimental methods in chemical engineering: Temperature‐programmed oxidation—TPO
Abstract Temperature‐programmed oxidation (TPO) probes the oxidative capacity and redox properties of solid materials—catalysts, metal oxides, perovskites, and carbonaceous deposits. It identifies coke type, distribution, and reactivity. TPO instruments pass an oxidizing gas (diluted O2$$ {\mathrm{O}}_2 $$, air, or less commonly N2O$$ {\mathrm{N}}_2 ...

Catalytic Hydrothermal Liquefaction of Polyethylene With Pt/C to Tune Product Selectivity
Pt/C‐catalyzed hydrothermal liquefaction of polyethylene in supercritical water enables time‐dependent control of product selectivity, producing paraffin‐rich oils at shorter reaction times and aromatic‐enriched products at longer times without external hydrogen. ABSTRACT Hydrothermal liquefaction (HTL) represents a promising thermochemical pathway for

Carbon emission assessment of tunnel infrastructures: From construction to operation
This study develops a lifecycle carbon accounting framework for tunnel infrastructures, covering design, construction, operation, maintenance, and dismantling. Applied to a subsea tunnel case, the framework reveals the carbon emission distribution among four typical tunnel types and highlights potential carbon offset methods for low‐carbon tunnel ...
