Carbon molecular sieve adsorbent monoliths and methods for making the same

Abstract

Methods for forming a carbon molecular sieve includes loading polymer fibers into a mold and heating the mold containing the polymer fibers to a temperature in a range from 50° C. to 350° C. to form a polymer monolith. The polymer monolith is then pyrolized by heating to a temperature in a range from 500° C. to 1700° C. A carbon molecular sieve monolith includes a first end and a second end opposite the first end, and carbon molecular sieve fibers aligned in parallel from the first end of the carbon molecular sieve monolith to the second end of the carbon molecular sieve monolith. Channels extend from the first end of the carbon molecular sieve monolith to the second end of the carbon molecular sieve monolith, and outer surfaces of the carbon molecular sieve fibers are joined. The carbon molecular sieve monolith has a cell density of greater than 500 cells per square inch.
