A system for combusting a methane stream in an ITM combustion reactor and a method of combusting the methane stream, wherein an optimized volumetric flow rate of the methane stream provides an off-stoichiometric molar ratio of methane to oxygen, which is provided by an ITM in the ITM combustion reactor, and the method further offers a relatively constant oxygen flux via the ITM as well as a prolonged membrane stability. Various embodiments of the system and the method are also provided.

System for combusting a methane stream and a method of combustion

A sealing agent for ion transport membranes (ITMs) includes a composition having a glass powder and a ceramic powder. The ceramic powder can include BaSrCoFeO(BSCF) or LaNiO(LNO). The ceramic powder can be identical to the ceramic powder from which the ITM is made. The glass powder can include PYREX glass. The sealing agent can be in the form of a paste. The sealing agent can be used to attach an ion transport membrane to one or more support tubes. The sealing agent includes from about 10 wt. % to about 40 wt. % glass powder and from about 60 wt. % to about 90% wt. % (BSCF) ceramic powder.
