Abstract
A method of making a gas adsorbent comprises dissolving a polymer in one or more first solvents to form a polymer solution; mixing an inorganic adsorbent with the polymer solution to form a precursor; molding the precursor; and leaching the first solvents from the precursor with a second solvent.
Claims29
A method of making a gas adsorbent, comprising:
- forming a polymer solution;
- mixing an inorganic adsorbent with said polymer solution to form a precursor;
- shaping said precursor;
- and
- leaching said precursor.
2 more elements
A method of making a gas adsorbent, comprising:
- dissolving a polymer in at least one first solvent to form a polymer solution;
- mixing an inorganic adsorbent with said polymer solution to form a precursor;
- molding said precursor;
- and
- leaching said at least one first solvent from said precursor.
2 more elements
A gas adsorbent system, comprising:
- a housing;
- a molded gas adsorbent disposed within said housing such that said gas adsorbent is prevented from shifting within said housing in the absence of a component that adheres said gas adsorbent to said housing, said gas adsorbent having been formed from a polymer solution.
A gas adsorbent system, comprising:
- a housing;
- a molded gas adsorbent within and substantially completely filling said housing such that said gas adsorbent is prevented from shifting within said housing in the absence of a component that adheres said gas adsorbent to said housing, said gas adsorbent having been formed from a polymer solution and an inorganic adsorbent.
