Abstract: Natural gas is stored in a closed vessel under a pressure of about 1400 to 4500 kPa using a carbon molecular sieve adsorbent having at least 80% of its particle pore volume as micropores having diameters greater than 0.55 nm and less than 0.65 nm, particularly about 0.6 to 0.65 nm. The capacity of such micropores for methane is at least 110 mL methane per mL of carbon (at 300 psig or 2,169 kPa abs.). The deliverable volume of natural gas from a vessel packed with carbon molecular sieve particles is at least 70 times the volume of the vessel. The deliverable volume is optimized by heating a carbonized polymer in the presence of carbon dioxide to increase the pore volume.

Abstract: Volatile organic compounds such as ketones and fluorocarbons are removed from vapor streams by contacting the vapor stream with a bed of an adsorbent comprising a binderless carbon molecular sieve. The carbon molecular sieves are characterized by their method of manufacture which includes forming a polymer from oxygen-free precursors and carbonizing directly to the finished sieve material in the absence of oxygen.

Abstract: A method is described for producing hydrophobic carbon molecular sieves. The method does not employ a binder to form or shape previously carbonized materials. Instead, a cross-linked oxygen-free polymer is first produced. Fine particles of this polymer are then pelletized or shaped as by simple extrusion. The extruded pellets are then carbonized in an oxygen-free atmosphere to yield binderless homogeneous particles of similar shape comprised of carbon sieves.
