Method for separating gases using a particulate composite material with carbon matrix
First Claim
1. A method of separating gases, comprising flowing gases to be separated past or through a particulate composite material with a carbon matrix and selectively adsorbing a portion of said gases to be separated into said material to separate the selectively adsorbed portion of gases from the gases to be separated wherein said material includes an essentially carbon microporous phase having a microporous volume between 0.1 and 1 cm3 /g, associated with an amorphous mineral dispersed phase essentially containing a mineral oxide selected from the group consisting of silicon, aluminum, titanium and magnesium oxides, said mineral dispersed phase being disposed on the carbon phase to a thickness of less than 10 nm.

Abstract
A method for separating gases wherein the gases to be separated are contacted with a particulate composite material with a carbon matrix to selectively adsorb gases. The material contains a microporous phase which is essentially carbon with a microporous volume between 0.1 cm2 /g and 1 cm2 /g, which is associated with an amorphous mineral dispersed phase containing an oxide of silicon, aluminum, titanium or magnesium disposed on the carbon phase at a thickness of less than 10 nm.
