Removal of CO2 in a multistage fluidized bed reactor by diethanol amine impregnated activated carbon.
TLDR
It has been found out that multistage fluidized bed reactor may be a suitable equipment for removal of CO2 from flue gas.Abstract:
To mitigate the emission of carbon dioxide (CO2), we have developed and designed a four-stage fluidized bed reactor. There is a counter current exchange between solid adsorbent and gas flow. In this present investigation diethanol amine (DEA) impregnated activated carbon made from green coconut shell was used as adsorbent. This type of adsorbent not only adsorbs CO2 due to the presence of pore but also chemically reacts with CO2 and form secondary zwitterions. Sampling and analysis of CO2 was performed using Orsat apparatus. The effect of initial CO2 concentration, gas velocity, solid rate, weir height etc. on removal efficiency of CO2 have been investigated and presented. The percentage removal of CO2 has been found close to 80% under low gas flow rate (0.188 m/s), high solid flow rate (4.12 kg/h) and weir height of 50 mm. From this result it has been found out that multistage fluidized bed reactor may be a suitable equipment for removal of CO2 from flue gas.read more

Highly selective and efficient removal of arsenic(V), chromium(VI) and selenium(VI) oxyanions by layered double hydroxide intercalated with zwitterionic glycine.
TL;DR: The obtained results show that the adsorption capacity and selectivity factor of oxyanions through ion exchange mechanism in NO3- LDH is lower than Gly-LDH, suggesting a chemical adsorptive mechanism via As(V)NH3+ bonding.

TL;DR: The growth rate of atmospheric carbon dioxide (CO2), the largest human contributor to human-induced climate change, is increasing rapidly and three processes contribute to this rapid increase: emissions, global economic activity, carbon intensity of the global economy, and the increase in airborne fraction of CO2 emissions.

The reaction of CO2 with ethanolamines
TL;DR: In this article, the rates of homogeneous reaction of mono-, di- and tri-ethanolamine by various workers are compared and it seems probable that a zwitterion is the intermediate in the formation of carbamate and that the reaction of DEA (but not of MEA) is catalysed by bases
