Abstract
A membrane for separating hydrogen from a gas mixture is provided on at least one side with a catalyst layer for a specific catalytic combustion process. A methanol reformation system so equipped can be brought rapidly to operating temperature, with the hydrogen-separating membrane being heated directly by performing the catalytic combustion process.
Claims12
A coated membrane for a hydrocarbon reformation system, comprising:
- a membrane for separating hydrogen from a gas mixture;
- and
- a coating on at least one side of the hydrogen separating membrane, said coating comprising a layer of a combustion catalyst for catalyzing combustion of a gas stream, wherein said layer is a porous layer or a structured layer leaving uncoated areas of the surface of said at least one side of the hydrogen separating membrane.
A methanol reformation system, comprising:
- a hydrogen-separating stage for separating hydrogen from a reformate gas, wherein the hydrogen separating stage comprises a hydrogen separating membrane coated on at least one side with a layer of a combustion catalyst, wherein said layer is a porous layer or a structured layer leaving uncoated areas of the surface of said at least one side of the hydrogen separating membrane.
A methanol reformation system comprising a reformation reaction unit comprising:
- a catalytic burner;
- a reformation reactor for reforming a methanol and steam mixture to produce a reformate gas containing hydrogen;
- and
- a hydrogen-separating stage for separating the hydrogen from the reformate gas, wherein the hydrogen separating stage comprises a hydrogen separating membrane coated on at least one side with a layer of a combustion catalyst, wherein said layer is a porous layer or a structured layer leaving uncoated areas of the surface of said at least one side of the hydrogen separating membrane.
A method for operating a methanol reformation system, comprising:
- providing a hydrogen separating membrane in said methanol reformation system, said hydrogen separating membrane having a layer of a combustion catalyst on at least one side thereof, wherein said layer is a porous layer or a structured layer leaving uncoated areas of the surface of said at least one side of the hydrogen separating membrane;
- during a cold start, before an operating temperature of the system is reached, subjecting the catalyst layer to a gas stream flow;
- and
- catalytically combusting the gas stream, thereby heating the hydrogen separating membrane to the operating temperature.
