A solid molecular basket sorbent for CO2 capture from gas streams with low CO2 concentration under ambient conditions
Abstract
In this paper, a solid molecular basket sorbent, 50 wt% PEI/SBA-15, was studied for CO2 capture from gas streams with low CO2 concentration under ambient conditions. The sorbent was able to effectively and selectively capture CO2 from a gas stream containing 1% CO2 at 75 °C, with a breakthrough and saturation capacity of 63.1 and 66.7 mg g−1, respectively, and a selectivity of 14 for CO2/CO and 185 for CO2/Ar.
