AD–OX: A sequential oxidative process for water treatment— Adsorption and batch CWAO regeneration of activated carbon [PDF]

, 2009
A sequential process for water treatment involving usual adsorption on activated carbon (AC) followed by wet air catalytic oxidation of the adsorbed pollutants has been carried out in a fixed bed reactor with a mixture of two model pollutants.

A routine method for the semi-quantitative determination of porous carbonaceous material in wastewater matrices

Frontiers in Environmental Engineering
The EU directive 2024/1990/EU mandates a fourth treatment stage for micropollutant removal in wastewater treatment plants (WWTPs). Porous carbonaceous materials (PCMs) such as powdered activated carbon (PAC) and biochar are effective but require ...

Renewable activated carbon from wood-based gasification char: A comprehensive study on physical activation

Carbon Resources Conversion
Wood gasification produces gasification char (GC), a carbonaceous by-product with limited sustainable valorisation strategies. The physical activation of wood-based GC as a precursor has received insufficient attention, likely due to the inherent ...

Gasification chars and activated carbon: Systematic physico-chemical characterization and effect on biogas production

Heliyon
Gasification residues/chars (GR) and activated carbon (AC) are added to wastewater treatment processes mainly as a fourth purification stage, e.g., to adsorb heavy metals or pharmaceutical residues. However, the effects of GR or AC, which are transferred

Scale-up activation of carbon fibres for hydrogen storage [PDF]

, 2010
In a previous study, we investigated, at a laboratory scale, the chemical activation of two different carbon fibres (CF), their porosity characterization, and their optimization for hydrogen storage [1]. In the present work, this study is extended to: (i)
