enhancement of co2 absorption rate by adding benzene-based hypercrosslinked polymers to amine solvents as a new strategy

The objective of this study is to measure the effect of promoter addition as well as mdea concentration for the co2 absorption into the aqueous solutions# tertiary amines are the most promising solvents for co2 capture, but they suffer from slow reaction rates# to solve the problem, here we report benzene-based hypercrosslinked polymer as promotor for co2 absorption in n-methyldiethanolamine solution# the co2 absorption rate increases up to 129% by adding hypercrosslinked polymers to amine solution# the ratio (benzene/crosslinker) was considered as an effective parameter on porosity and structure of hypercrosslinked polymer and consequently three hypercrosslinked polymers were synthesized which differed in the ratio# hcp-3 with moderate benzene to crosslinker ratio 1:3 showed the best performance#
