Carbon dioxide capture and concentration from combustion flue gases byadsorption based technology

Mesoporous silica SBA-15 will be synthesized in the lab, and then characterized by

XRD, SEM or TEM technique. The obtained mesoporous silicas will then be functionalized

with four types of amino groups: monomeric unhindered (3-aminopropyl) and hindered

(pyrrolidinepropyl), polymerized aminopropyl group and polyethyleneimine (PEl) based on the

graft method reported in the literature.

This type of ordered mesoporous materials offer structural characteristics such as

large pore size, high surface area, and a large number of highly dispersed active sites on the

pore surface, which facilitates the distribution of amines throughout the pore space, thereby

promoting the C02 adsorption.

BET surface area, pore volume and pore size distribution, surface properties and

sorbate-adsorbent interactions of SBA-15 materials will be determined using standard

techniques, such as nitrogen adsorption at 77 K, and spectroscopic characterizations using

TGAIDSC and FT-IR. Adsorption and diffusion characterizations and column dynamics will

also be performed to test the CO2 capture ability of the material.
