Reports Summarize Chemical Engineering Findings from University of Utrecht

February 19, 2014



By a News Reporter-Staff News Editor at Journal of Engineering -- Investigators publish new report on Chemical Engineering. According to news reporting out of Utrecht, Netherlands, by VerticalNews editors, research stated, "This study focuses on regenerable sorbents for post-combustion CO2 capture at low temperature (373 K). K2CO3 loaded on three different supports, carbon nanofibers (CNF), alumina (gamma-Al2O3), and activated carbon (AC), was investigated."

Our news journalists obtained a quote from the research from the University of Utrecht, "K2CO3-CNF revealed excellent properties as CO2 sorbent, displaying capacities of 1.2-1.6 mmol g(-1) and fast desorption kinetics at low temperatures (423 K). This temperature was too low to completely regenerate K2CO3-Al2O3 and K2CO3-AC, and consequently, these sorbents lost 8% and 50%, respectively, of their capacity after the first absorption-desorption cycle."

According to the news editors, the research concluded: "K2CO3-CNF could be regenerated to restore 80% of its capacity with a low energy input, estimated at 2-3 GJ/ton CO2, which is competitive to currently used amines."
