NOVEL SOLID MATERIALS AND METHOD FOR CO2 REMOVAL FROM GAS STREAM
First Claim
1. A system for removing carbon dioxide from a process gas generated during the combustion of a fuel, said system comprising at least one absorption vessel through which the process gas may be forwarded, said absorption vessel being provided with a sorbent material which is operative for reversibly collecting carbon dioxide from the process gas being forwarded through the sorbent material, said sorbent material comprising at least one amine, at least one carbon dioxide activating catalyst, and at least one porous material supporting the at least one catalyst and the at least one amine.

Abstract
A system (10) for removing carbon dioxide from a process gas generated during the combustion of a fuel comprises at least one absorption vessel (12, 14) through which the process gas may be forwarded. The absorption vessel (12, 14) is provided with a sorbent material (50) which is operative for reversibly collecting carbon dioxide from the process gas being forwarded through the sorbent material (50). The sorbent material (50) comprises at least one amine, at least one carbon dioxide activating catalyst, and at least one porous material supporting the at least one catalyst and the at least one amine.

-
23. A method of removing carbon dioxide from a process gas generated during the combustion of a fuel, said method comprising:
-
bringing the process gas into contact with a sorbent material which is operative for reversibly collecting carbon dioxide from the process gas; and bringing said process gas into contact with a sorbent material comprising at least one amine, at least one carbon dioxide activating catalyst, and at least one porous material supporting the at least one catalyst and the at least one amine, such that carbon dioxide is absorbed by said at least one amine under the influence of said at least one carbon dioxide activating catalyst.
