Abstract
The supported amine-polyol sorbent of the present invention comprises about 1 wt % to about 25 wt % amine, about 1 wt % to about 25 wt % polyol, with the balance being support. This sorbent is capable of absorbing and desorbing carbon dioxide at relatively high rates at ambient temperatures, thereby improving carbon dioxide sorption capacity.
Claims7
A method for forming a supported amine-polyol sorbent comprising the steps of:
- a. wetting a high surface area support;
- b. contacting said wetted high surface area support with amine and polyol to form an amine-polyol mixture;
- and
- c. drying said amine-polyol mixture to deposit said amine and said polyol on said high surface area support and to form the supported amine-polyol sorbent.
1 more element
A method for forming a supported amine-polyol sorbent as in claim 6 wherein contacting said wetted high surface area support with amine and polyol comprises:
- a. dissolving said amine in a solvent to form an amine solution;
- b. mixing said amine solution and said wetted high surface area support to form a first mixture;
- and
- c. combining said first mixture with said polyol to form said amine-polyol mixture;
- and wherein drying said amine-polyol mixture comprises evaporating said solvent out of said amine-polyol mixture.
