Evaluation of a Primary Amine-Functionalized Ion-Exchange Resin for CO2 Capture
TLDR
In this paper, a primary amine functionalized polymeric ion exchange resin (Lewatit VP OC 1065, Lanxess) was evaluated for use in CO2 capture applications.Abstract:
A primary amine-functionalized polymeric ion-exchange resin (Lewatit VP OC 1065, Lanxess) was evaluated for use in CO2 capture applications. The polymeric resin was characterized by SEM, DRIFTS-IR, N2 adsorption isotherms, and packed bed sorption measurements to determine some of the characteristic properties of the resin. Capture capacities ranging from 1.85 to 1.15 mol CO2/kg sorbent were obtained in a packed bed reactor exposed to 10 vol % CO2 in N2 at adsorption temperatures ranging from 30 to 70 °C. The capture capacity of the resin was stable over 18 adsorption/regeneration cycles. The resin was evaluated through thermogravimetric analysis to have a low moisture adsorption (1.5 mol H2O/kg sorbent). It is possible to completely regenerate the resin under 1 atm of CO2 at 200 °C.read more

Recent advances in solid sorbents for CO2 capture and new development trends
Junya Wang,Liang Huang,Ruoyan Yang,Zhang Zhang,Jingwen Wu,Yanshan Gao,Qiang Wang,Dermot O'Hare,Ziyi Zhong +8 more
TL;DR: In this article, the authors organize the CO2 sorbents according to their working temperatures by classifying them as such: (1) low-temperature ( 400 °C), since the sorption capacity, kinetics, recycling stability and cost are important parameters when evaluating a sorbent.
