Abstract
The invention provides a composite material formed from an inorganic mesoporous, or mesoporous-like, material that is dispersed throughout a polymeric matrix formed by a crosslinked polymer that has acidic- or basic-residues and which may also optionally have further acidic- or basic-residues grafted onto the inorganic mesoporous material. The resulting composite material may be used to remove acidic or basic impurities from a gas in need thereof and can be easily regenerated.
Claims20
A composite material comprising:
- a particulate adsorbing material;
- and
- a crosslinked polymer comprising acidic or basic residues, wherein
- the particulate adsorbing material is dispersed throughout a polymer matrix formed by the crosslinked polymer, and the particulate adsorbing material is selected from the group consisting of mesoporous silica, mesoporous carbon, mesoporous zinc oxide, a bentonite clay, and a kaolinite clay.
