Hydrogen purification using membrane reactors

Methane steam reforming(MSR) was studied in a membrane reactor(MR) with a Pd-based and a porous alumina membranes. MRs showed methane conversion higher than that foresaw by the thermodynamic equilibrium for a traditional reactor(TR). Silica membranes prepared at KRICT were characterized with permeation tests on single gases(N?, H?and CH?). These silica membranes can be also used for high temperature applications such as H?separation CO?hydrogenation for methanol production is another reaction where H?O selective removal can be performed with these silica membranes.
