Membrane reactors hydrogen production from natural

In Canada, hydrogen production from natural gas via a fluidised bed reactor with hydrogen purification via a selective membrane is under investigation. Also, a methanol micro-reformer which includes an integrated metal membrane purification unit is being developed.

Another interesting field involving membrane reactors is the partial oxidation of methane to methanol, which is a process for the catalytic conversion of methane from natural gas and air oxygen to methanol by the partial oxidation as well as the steam reforming of methane, ethanol or glycerol for hydrogen production (Basile et a/., 2011 lulianelli et al, 2010,2011). 

In the last three decades, membrane-based gas separation has become a well-established unit operation for a variety of important applications. Gas separation membranes operate in the chemical industry in hydrogen separation, monomer recovery, the enrichment of nitrogen from air, and natural gas treatment. Recovery of hydrogen from the purge gas of an ammonia reactor was established around 1980. Vinylchloride monomer recovery from the PVC production process was started up about 10 years later. Recently, the recovery of propylene from polypropylene purge bins became feasible. The removal of sour gases from natural gas as well as biogas operates reliably, today. ...
