Post-Combustion Carbon Dioxide Capture By Porous Carbon From Cassava Leaves In A Fixed-Bed

Porous carbon has been gaining attention in carbon dioxide (CO2) capture. Its physical and chemical characteristics can be enhance through some modifications by activating it with an activating agent. In this research, cassava leaves was used as a precursor to prepare adsorbents for CO2 capture. Cas...
