Abstract
Disclosed herein are carbon molecular sieves and methods of making the same through the pyrolysis of a polymer precursor in the presence of a reactive gas stream including a hydrogen source.
Claims22
A process for controlling a pore structure of a carbon molecular sieve comprising:
- providing a polymer precursor comprising a rigid microporous polymer;
- heating the polymer precursor in a chamber to at least a temperature at which the polymer precursor undergoes pyrolysis;
- and
- flowing a reactive gas stream through the chamber during the heating to control the pore structure of the carbon molecular sieve,
- wherein the reactive gas stream comprises H2 and the carbon molecular sieve comprising the polymer precursor.
