Further recommendations have been proposed with the aim of increasing the mercury removal efficiency using carbon activation processes with lower energy input, while achieving similar or even higher efficiencies.
In summary, we have demonstrated a feasible and very simple method for the synthesis of N-doped microporous carbon via a carbonization-activation process by using urea formaldehyde resin co-polymerized with furfuralcohol, which showed tunable surface area and high nitrogen content.
Here, in this study, for the purpose of further improving the CO2 adsorption capacity, furfuralcohol was chosen to form a copolymer with urea and formaldehyde and treated by the same carbonization-activation process to make porous carbon.
Novel nitrogen-doped porous carbon/Sn composites (NCSs) are successfully prepared by the carbonization-activation process.
Herein, we have successfully prepared three kinds of hierarchically porous nitrogen-doped carbons with different morphologies (particles, nanowires, and nanoribbons) through a carbon dioxide activation process.
The main reason for such behavior is probably related to the presence of thermally stable phosphorus complexes that remain on the carbon surface after the activation process.
The "self-template" procedure is the key point for creating the skeleton of carbon, and the KOH activation process is able to regulate pore size distribution and increase specific surface area.
In this study, a simple carbonization method has been presented to prepare porous carbons as electrode materials without activation process, in which inexpensive, reproducible calcium lignosulfonate serves as carbon source.
A hybrid carbon materials with three dimensional network carbon nanotubes in activated carbon was prepared by an in situ activation process.
The activation process of a spherical activated carbon (SAC) from Kureha Carbon was analysed and the behaviour of these materials to adsorb low concentration volatile organic compounds was studied.
