CO2 Adsorption: Model Prediction and Alternative New Adsorbent

The objective of this project is to determine the potential of C02 adsorption on pentace
triptera leaves and a suitable model to describe its adsorption equilibrium relationship
and to fit the adsorption data of CO2 on molecular sieve 5A and on activated carbon
using Langmuir and Sips model. Leaves were collected and cleaned. CHONS analysis
was performed on the leaves. Data for adsorption of CO2 on molecular sieve 5A and on
activated carbon; AC1 was obtained from literature. Microsoft Excel and Polymath 5.1
software were used for data correlation.
The potential of CO2 adsorption on pentace triptera leaves could not be determined due
to equipment failure and therefore a model to describe its adsorption equilibrium
relationship could not be deduced. Sips model showed a better fit for adsorption of CO2
on both molecular sieve 5A and activated carbon at all temperatures studied.
