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 ...

Determining the Effect of Grain Size on the Microstructure and Oxidation of Nuclear Graphite

Carbon Energy, EarlyView.
Superfine‐grained graphite is developed, showing oxidation resistance comparable to that of medium‐grained graphite. The study reveals that two intrinsic parameters govern its performance: reactive site concentration dictates chemical kinetics, whereas pore tortuosity controls oxidant diffusion.

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
