Aminosilane-Functionalized Cellulosic Polymer for Increased Carbon Dioxide Sorption

Abstract: Improvement in the efficiency of CO 2 separation from flue gases is a high-priority research area to reduce the total energy cost of carbon capture and sequestration technologies in coal-fired power plants. Efficient CO 2 removal from flue gases by adsorption systems requires the design of novel sorbents capable of capturing, concentrating, and recovering CO 2 on a cost-effective basis. This paper describes the preparation of an aminosilane-functionalized cellulosic polymer sorbent with enhanced CO 2 sorption … Show more

“…For the modification performed with the use of MA, the increased intensity of the absorption bands related to the C-O, C=O and C=C bonds was observed [30]. In contrast, the cellulose treated with VTMS indicated signals of the chemical groups containing silicon atoms [31,32] and C=C bonds. In addition, in both cases, a decrease in the intensity of the absorption band of the -OH moieties was observed as a result of the creation of ester and Si-O bonds.…”

“…It could be assigned to a reduction in O-H bonds. The two weak peaks which are found at around 1249 and 802 cm -1 are attributed to Si-C stretching bond (Hassan & Khan 2008;Pacheco et al 2011). Figure 3 shows XRD patterns of cellulose nanocrystals after neutralization and silanization.…”

“…The value of DA for cellulose is 0, while for cellulose tri acetate, it is 3 [55,56]. The acetyl group in CA minimizes the extent of hydrogen bonding among the polymeric chains having hydroxyl groups in their skeleton, and enhances chain mobility [57]. The polymeric chains become flexible after less interaction with hydroxyl groups.…”
