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 ...

Single iron redox sites boost Methanol-SCR at low temperature
Selective catalytic reduction of NOx to N2 by methanol as a reducing agent presents a prospective solution for the removal of NOx from the exhaust of methanol engines and the coal-fired power plant, but it confronts the problem of insufficient deNOx ...

Lithium carbonate (Li2CO3) obtained from the black mass of recycled lithium batteries is dissolved in water under controlled conditions to remove lithium fluoride (LiF), which is present at a concentration of 3.08 % by weight. The dissolution is carried out at temperatures below 10 °C, and it has been demonstrated that lower temperatures result in ...

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 ...
