Processes for chemical functionalization of materials are described. The processes generally include chemical reaction between a thiol group of a first compound or material and an alkene group or alkyne group of a second compound or material. Also disclosed are functionalized materials and compounds suitable for functionalizing a material.

A process and system for separating COfrom a flue gas stream is disclosed. The process involves (a) contacting a flue gas stream containing water vapor and COwith an ionic absorbent under absorption conditions to absorb at least a portion of the COfrom the flue gas stream and form a CO-absorbent complex; wherein the ionic absorbent comprises a cation and an anion comprising an amine moiety; and (b) recovering a gaseous product having a reduced COcontent.

Process for the separation of carbon dioxide from flue gas

An aqueous ionic absorbent solution is disclosed containing (a) about 15 wt. % to about 80 wt. % of one or more diluents, based on the total weight of the aqueous ionic absorbent solution; and (b) an ionic absorbent containing a cation and an anion comprising an amine moiety.

Aqueous solutions of amine functionalized ionic compounds for carbon capture processes

Disclosed herein is a method for improving the total energy demand required to separate carbon dioxide (CO) from an aqueous ionic absorbent solution in a post-combustion carbon capture process. The method involves (a) contacting a flue gas stream containing COwith an aqueous ionic absorbent solution under absorption conditions to absorb at least a portion of the COfrom the flue gas stream and form a CO-aqueous ionic absorbent solution stream, wherein the aqueous ionic absorbent solution comprises one or more diluents and an ionic absorbent containing a cation and an anion comprising an amine moiety; and (b) subjecting at least a portion of the CO-aqueous ionic absorbent solution stream to desorption conditions to form a CO-rich stream and an aqueous ionic absorbent solution stream having a reduced COcontent.

A method for removing contaminants from synthetic resin material includes contacting a particulate synthetic resin material containing at least one contaminant with a solvent other than carbon dioxide. At least a portion of the contaminant is removed from the particulate synthetic resin material and becomes dispersed in the solvent. The solvent, with the contaminant dispersed therein, is then removed from the particulate synthetic resin material. Thereafter, at least a portion of the solvent still contained on the synthetic resin material is removed by contacting the particulate synthetic resin material with liquid carbon dioxide to dissolve the solvent into the carbon dioxide.
