Sorbent polymer composites and a solution-casting method of making hydrophobic sorbent polymer composites for CO2 adsorption applications are described. The sorbent polymer composites are comprised of a polymer matrix, a dispersed CO2 sorbent, and an optional filler particle for hydrophobicity modification.

The invention provides a system for manufacturing graphene wool which includes a receptacle, a graphene growth substrate locatable inside the receptacle, a heating device for increasing the temperature inside the receptacle, an inlet gas flow communication with the receptacle for controlling the introduction of gaseous substances into the receptacle, and a cooling device for rapidly decreasing the temperature inside the receptacle. The invention extends to a method for manufacturing graphene wool and to an air pollutant trap which includes: a sorbent, and a housing for housing the sorbent, wherein the sorbent includes graphene.

A sorbent product, including from about 1 wt % to about 99 wt %, based on the total weight of the sorbent product, of at least one base sorbent material; and from about 1 wt % to about 99 wt %, based on the total weight of the sorbent product, of at least one binder. The sorbent product may further include at least from about 0 wt % to about 99% wt %, based on the total weight of the sorbent product, of at least one additional additive. Methods for making same and methods and systems for controlling multiple pollutants are also included.

Carbonaceous material that is activated to form precursor activated carbon is further enhanced by doping with copper and nitrogen and calcining. The resultant sorbent material has excellent catalytic properties which are useful in the field of fluid purification.

Method and apparatus for separating a target substance from a fluid or mixture. Capsules having a coating and stripping solvents encapsulated in the capsules are provided. The coating is permeable to the target substance. The capsules having a coating and stripping solvents encapsulated in the capsules are exposed to the fluid or mixture. The target substance migrates through the coating and is taken up by the stripping solvents. The target substance is separated from the fluid or mixture by driving off the target substance from the capsules.
