Abstract:
1. A method of removing hydrogen in situ from a reactor or catalyst system producing hydrogen, the method comprising the steps of: contacting a hollow fiber membrane with a reaction gas mixture, the membrane comprising a porous stainless steel support having an inner diameter of approximately 30 microns to approximately 1500 microns, an outer diameter of approximately 100 microns to approximately 2000 microns, an intermediate layer of ceramic coated on the stainless steel support, and a hydrogen selective dense layer coated on the outer diameter, the reaction gas mixture comprising either methane and steam or carbon monoxide and steam; recovering a high purity hydrogen stream from a permeate side of the membrane; and recovering a hydrogen-lean stream from a non-permeate side of the membrane.
