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.
