Patent ID: 7662349

Claim:
A reactor comprising: a first reaction part and a second reaction part, each comprising a reaction channel adapted to have a reactant flow therethrough, wherein the reactant is supplied to the first reaction part and the second reaction part to cause a reaction of the reactant, and the first reaction part and the second reaction part are arranged to form a gap therebetween; a heat insulating container covering at least an entirety of the first reaction part, the second reaction part, and the gap, wherein a pressure within an inner space of the heat insulating container including the gap is lower than atmospheric pressure; and at least one getter material disposed in a space including the gap in the inner space of the heat insulating container, the getter material being disposed to at least one of a face of the first reaction part at a position corresponding to the gap, and a face of the second reaction part at a position corresponding to the gap; wherein: the getter material is provided with a heater to heat the getter material so as to activate the getter material; the heater comprises an electric heating wire and a lead wire to supply electric power to the electric heating wire; the lead wire is wired to penetrate the heat insulating container to reach outside; and the reactor further comprises cutting means to cut off the lead wire at a position between a face of the first reaction part or the second reaction part and the inner face of the heat insulating container, after the getter material is heated to be activated.
