摘要:
The present invention provides (i) a method and system for stabilizing the performance of amine-containing CO2 adsorbents using wet feed gas and/or wet purge gas and (ii) a method for regeneration of deactivated amine-containing CO2 adsorbents via hydrolysis of the urea groups formed during deactivation.
摘要:
The present invention provides methods and systems for carbon dioxide, hydrogen sulfide and other acid gases capture via adsorption at high pressure using mesoporous materials.
摘要:
The present invention provides an amine functionalised adsorbent for use in dry scrubbing process. The adsorbent comprises amine functionalised mesoporous silica in which the amine groups are present at or near the surface of the silica, including within the pore walls and channels of the silica. The present invention further provides methods of preparing the adsorbent and of using the adsorbent for the adsorption of CO2 and/or other acid gases.

摘要:
The present invention provides a functionalized adsorbent for removal of acid gases, which comprises a pore-expanded mesoporous support having a pore volume of between 0.7 and 3.6 cc/g, a median pore diameter of between 1 and 25 nm, and a BET surface area of between 500 and 1600 m2/g. The support is functionalized by addition of acid-gas reactive functional groups within the pores and external surface of said support material. Also provided are methods of manufacturing the adsorbent and methods of use.
