Patent ID: 7713317

Claim:
A reactor comprising: a high-temperature reaction unit which causes a first reaction of a first reaction material to create a second reaction material and a product; a low-temperature reaction unit which causes a second reaction of the second reaction material at a temperature lower than in the high-temperature reaction unit; a coupling pipe which is interposed between the high-temperature reaction unit and the low-temperature reaction unit, which has first and second opposite ends respectively connected to a part of one side wall of the high-temperature reaction unit and to a part of one side wall of the low-temperature reaction unit, and which transfers the first reaction material and the product created with the first reaction material between the high-temperature reaction unit and the low-temperature reaction unit; an external flow pipe having one end joined to the low-temperature reaction unit and including a first flow pathway for supplying the first reaction material to the high-temperature reaction unit through the low-temperature reaction unit and a second flow pathway for discharging the product from the high-temperature reaction unit through the low-temperature reaction unit; and a heat insulating package which accommodates the high-temperature reaction unit, the low-temperature reaction unit, and the coupling pipe, and also accommodates a part of the external flow pipe; wherein the external flow pipe extends outwardly through the heat insulating package; and wherein the external flow pipe supports the low-temperature reaction unit to the heat insulating package so that the high-temperature reaction unit, the low-temperature reaction unit, and the coupling pipe are situated apart from all inner surfaces of the heat insulating package.
