Integration of High‐p, Low‐T CO2 Electrolysis with Pressure Swing Adsorption Purification

open access: yesChemie Ingenieur Technik, EarlyView.
We evaluate a high‐p low‐T CO2 electrolysis (LTCE) cell with a pressure swing adsorption (PSA) to compare cascade vs. recycle operation. Although a cascade yields high CO selectivity but limited yield, a full recycle achieves near‐quantitative CO production, highlighting gas recycling as essential for LTCE/PSA systems.

THE IMPACT OF A CARBON TAX ON INTERNATIONAL TOURISM [PDF]

open access: yes
A simulation model of international tourist flows is used to estimate the impact of a carbon tax on aviation fuel. The effect of the tax on travel behaviour is small: A global $1000/tC would change travel behaviour to reduce carbon dioxide emissions from

When to regulate airports: A simple rule [PDF]

open access: yes
Landing fees at airports are regulated almost all over the world since airports are assumed to abuse their market power. We find that monopolistic airports have an incentive to restrain landing fees when they generate additional non-aviation revenues and

Integrated and closed‐loop biorefinery strategies for efficient waste valorization and biofuel production

open access: yesThe Canadian Journal of Chemical Engineering, EarlyView.
Abstract Advancements in biofuel production technologies are essential for reducing global dependence on fossil fuels and addressing their overexploitation. Many valuable components of biomass, such as cellulose, hemicellulose, and lignin, remain underused in traditional biorefineries, which typically rely on a single feedstock to produce a primary ...

General-aviation's view of progress in the aviation weather system [PDF]

open access: yes
For all its activity statistics, general-aviation is the most vulnerable to hazardous weather. Of concern to the general aviation industry are: (1) the slow pace of getting units of the Automated Weather Observation System (AWOS) to the field; (2) the ...

Take Off to Superiority: The Evolution & Impact of U.S. Aircraft in War [PDF]

open access: yes, 2019
Military aviation has become a staple in the way wars are fought, and ultimately, won. This research paper takes a look at the ways that aviation has evolved and impacted wars across the U.S. history timeline.

Durene conversion in a methanol‐to‐jet process: Exploring conversion at 150–350°C over different acid catalysts

open access: yesThe Canadian Journal of Chemical Engineering, EarlyView.
Abstract Acid catalyzed conversion of durene by isomerization, disproportionation, and transalkylation is of interest to the development of a methanol‐to‐jet process to reduce the amount of durene in the kerosene. It was of interest to determine whether durene conversion could be performed at a temperature lower than 350°C.
