SILICA-CONTAINING HYDROGEN-SEPARATING MATERIAL AND PROCESS FOR PRODUCTION THEREOF, AND HYDROGEN SEPARATION MODULE AND HYDROGEN PRODUCTION APPARATUS EACH COMPRISES THE HYDROGEN-SEPARATING MATERIAL

摘要

Disclosed are: a hydrogen-separating material which is applicable to hydrogen-separating membranes and the like having high thermal impact resistance and excellent hydrogen-separating properties; a process for producing the hydrogen-separating material; and a hydrogen separation module and a hydrogen production apparatus, each of which is produced using the hydrogen-separating material. The hydrogen-separating material is produced by forming a silica glass film on a porous support having a linear thermal expansion coefficient of 2 × 10-6 /K or less. The process for producing the hydrogen-separating material comprises: a porous support formation step of forming a porous support comprising a porous silica glass; and a silica glass film formation step of forming a silica glass film on the surface of the porous silica glass. The hydrogen separation module comprises the hydrogen-separating material and a water vapor reforming catalyst. The hydrogen production apparatus is equipped with the hydrogen separation module.
