Solvent‐Driven Pore Engineering in Coffee‐Derived Activated Hydrochar: Implications for Post‐Combustion CO2 Capture

Carbon Energy, EarlyView.
Solvent washing of coffee‐ground hydrochars produces activated carbons with tunable pore sizes while maintaining surface area. Removing non‐polar contaminants enhances microporosity, increasing CO2 uptake by 40%. Moderate pore sizes (9–12 Å) yield optimal CO2:N2 selectivity, whereas smaller pores reduce selectivity due to stronger interactions between ...

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

Chemie 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.

Revisiting acidulation for tall oil and lignin manufacturing

The Canadian Journal of Chemical Engineering, EarlyView.
Abstract Tall oil is a byproduct of the kraft pulping process when softwood is used as raw material. As the production of softwood‐based pulp is in high demand, the optimization of the tall oil production process needs to be revisited to ensure the highest quality and quantity of tall oil manufacturing. In this work, the process for tall oil production

Glycerol carbonate formation from glycerol and dimethyl carbonate using lithium‐based catalysts

The Canadian Journal of Chemical Engineering, EarlyView.
Abstract Excess glycerol from biodiesel production can be sustainably converted into value‐added products like glycerol carbonate, for its use in polymers, solvents, and as ecofriendly alternative as green chemical in various chemical industries. This study aims to synthesize a catalyst optimized for the glycerol and dimethyl carbonate (DMC) conversion
