Sustainable Aviation Fuel—An Innovative Approach for Developing an Optimized Methanol‐Based Production Pathway

Chemie Ingenieur Technik, EarlyView.
Growing air traffic increases the contribution of aviation fuels to global emissions. With few viable alternatives for decarbonizing aviation, Sustainable Aviation Fuels (SAF) are a key lever. Green methanol enables a flexible synthetic production pathway, but realizing a specification‐compliant 100% drop‐in fuel requires overcoming significant ...

Application of artificial neural network and general machine learning modelling on CO2 adsorption in moisture equilibrated South African high and medium rank coals

The Canadian Journal of Chemical Engineering, EarlyView.
Abstract This study investigates the effect of moisture on CO2 adsorption in South African coals using both experimental and machine learning approaches. Three coal samples (SL, TN, and EM) with varying ranks (RoVmr: 3.49%, 1.26%, and 0.64%, respectively) were collected from different regions of South Africa.

Role of Lewis centres on ethanol dehydrogenation over the Cu‐Cr/γ‐Al2O3 system

The Canadian Journal of Chemical Engineering, EarlyView.
Cu–Cr interactions on alumina enhance Lewis acid site density, boosting selectivity towards ethanol dehydrogenation products. Soft coke formation on copper and Cu–Cr sites drives deactivation, shifting the reaction towards unwanted dehydration products.

Experimental methods in chemical engineering: Temperature‐programmed desorption—TPD

The Canadian Journal of Chemical Engineering, EarlyView.
Abstract Temperature‐programmed desorption (TPD) characterizes the surface active sites of functional materials, such as adsorbents (metal hydrides, porous carbons, zeolites, metal–organic frameworks, for example) and catalysts. Solids surfaces are pre‐treated to remove moisture, contaminants, and previously adsorbed species, then a probe molecule (NH3$

Scale‐down before you scale‐up: Organic electronic materials scaled at Xerox Research Centre of Canada

The Canadian Journal of Chemical Engineering, EarlyView.
Abstract Organic electronics have emerged as a key class of functional materials for organic light‐emitting diodes (OLEDs), organic photovoltaics (OPVs), organic field‐effect transistors (OFETs), sensors, and printed electronics. However, commercialization remains dependent on the ability to reproducibly synthesize and manufacture high‐performance ...
