Abstract
Activated carbon honeycomb-monoliths with different textural properties were prepared by chemical activation of African palm shells with H3PO4, ZnCl2 and CaCl2 aqueous solutions of various concentrations. The adsorbents obtained were characterized by N2 adsorption at 77 K, and their carbon dioxide adsorption capacities were measured at 273 K and 1 Bar in volumetric adsorption equipment. The experimental adsorption isotherms were fitted to Langmuir and Tóth models, and a better fit was observed to Tóth equation with a correlation coefficient of 0.999. The maximum experimental values for adsorption capacity at the highest pressure (2.627–5.756 mmol·g−1) are between the calculated data in the two models.
Highlights
Adsorbent porous materials have become very important for adsorption-based processes in environmental and catalytic applications
This work is aimed at CO2 adsorption on activated carbon monoliths at 273 K and 1 Bar, obtained from African palm shell by chemical activation with H3PO4, ZnCl2 and CaCl2 aqueous solutions of various concentrations
The results of carbon dioxide adsorption at 273 K on three series of activated carbon monoliths prepared by impregnation of African palm shells with H3PO4, ZnCl2 and CaCl2 aqueous solutions show that these materials can be interesting for CO2 capture
Summary
Adsorbent porous materials have become very important for adsorption-based processes in environmental and catalytic applications. The most used adsorbents are zeolites, pillared clays, mesoporous silica materials, activated carbons and more recently, Metal Organic Frameworks. (MOFs) [1,2,3,4,5,6]. Carbon-based materials are well known, being widely applied at industrial scale as adsorbents [3,5,6,7], electrodes [8,9], fibers [9], nanotubes [10], monoliths [11,12], catalysts and/or and catalytic supports [4,11]
