Comment on "Potential for environmental impact due to acid gas leakage from wellbores at EOR injection sites near Zama Lake, Alberta" by D.M. LeNeveu (2012)

Abstract

A novel class of amine-supported sorbents based on amine-bridged mesoporous polysilsesquioxane was developed via a simple one-pot sol-gel process. The new sorbent allows the incorporation of a large amount of active groups without sacrificing surface area or pore volume available for CO2 capture, leading to a CO2 capture capacity of 3.2 mmol g?1 under simulated flue gas conditions. The sorbent is readily regenerated at 100?C and exhibits good stability over repetitive adsorption-desorption cycling. ? 2011 Society of Chemical Industry and John Wiley & Sons, Ltd
