Title: Adsorption studies of CO2 capture on carbon from waste PET

Abstract

Statement of the Problem: It is well recognized that porous carbons have been successfully prepared from novel raw materials and tested for their suitability as adsorbents. Also, many waste materials are used for the preparation of carbon to be used as adsorbent. In this work, carbon prepared from the PET waste is characterized and tested for its adsorption capacity for CO2 at various concentration levels of CO2 in the feed gas. The carbon was found to maintain stability over several adsorption cycles without significant decrease in adsorption capacity. Further, this carbon adsorbent was activated and tested for adsorption of CO2. The adsorbent was found to have surface area of about 1400 m2/g and adsorption capacities in the range of 1.3-1.5 mmol/g. The kinetics of the adsorption process was modeled using fraction order model. Further, the fixed bed adsorption process was modeled to estimate the breakthrough profiles at different experimental conditions.
