Separation Membrane Development for Hydrogen
Conference

OSTI ID:761640
A ceramic membrane has been developed to separate hydrogen from other gases. The method used is a sol-gel process. A thin layer of dense ceramic material is coated on a coarse ceramic filter substrate. The pore size distribution in the thin layer is controlled by a densification of the coating materials by heat treatment. The membrane has been tested by permeation measurement of the hydrogen and other gases. Selectivity, 10,000 to 50,000, of the membrane has been achieved to separate hydrogen from carbon monoxide. The permeability constant of hydrogen through the ceramic membrane was about 46,000 Barrer at the room temperature, which is about the same as Pd-Ag membrane at 400 C.
