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 ...

Gasification of the Char Residues with High Ash Content by Carbon Dioxide
EnergiesTo increase the carbon conversion of char in gasification, this paper aimed to reveal the gasification behaviours of char residues. Char residues with different ash contents in this work were prepared from Shenmu char and Tejing char. Those char residues

The “Rodenator”: an efficient device for controlling field mice and root voles? [PDF]
, 2008 Field mice (Microtus arvalis), wood mice (Apodemus sylvaticus) and root voles (Arvicola terrestis) constitute a big threat to the organic apple orchards in South Tyrol. The use of rodenticides on the fields is not allowed in organic farming.

The Canadian Journal of Chemical Engineering, EarlyView.Research frontiers in using biochar for heavy metal remediation. Abstract Heavy metal contamination of water has long been a serious environmental issue. Biochar and biochar‐based composites are emerging as effective and sustainable solutions for heavy metal removal due to their strong adsorption abilities and environmentally friendly nature.

The 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 ...

The Canadian Journal of Chemical Engineering, EarlyView.An overview of municipal solid waste torrefaction under various sweep gases. Abstract This study investigates the impact of torrefaction on municipal solid waste (MSW) fractions, focusing on energy recovery, calorific value enhancement, mass yield reduction, and energy densification under both nitrogen (N2) and carbon dioxide (CO2) atmospheres.

A study of Ni‐Co/CeO2 catalyst derived from metal–organic framework for dry reforming of methane
The Canadian Journal of Chemical Engineering, EarlyView.Abstract The efficacy of cobalt‐doped, MOF‐derived catalysts for dry reforming of methane (DRM) was examined. The focus was on the influence of varying nickel and cobalt molar ratios on catalytic performance. Three catalysts with Ni:Co ratios of 1:1, 1:0.5, and 0.5:1, were synthesized and tested with cerium oxide as a constant support. The DRM reaction
