Abstract:
1. A reactor for reacting first and second reactants while permitting the flows of the reactants, comprising: a channel forming body internally formed with a plurality of channels each including a first inlet path having the first reactant introduced thereinto, a second inlet path having the second reactant introduced thereinto, a junction channel connected with a downstream side of the first inlet path and that of the second inlet path for causing the first reactant flowing via the first inlet path and the second reactant flowing via the second inlet path to join, and a reaction channel connected with a downstream side of the junction channel for reacting the both reactants joined in the junction channel with each other while permitting the flows of the reactants, wherein: the channel forming body includes a base plate, a first sealing member bonded to one surface of the base plate while covering the one surface, and a second sealing member bonded to the other surface of the base plate while covering the other surface; a plurality of first inlet grooves for forming the first inlet paths are formed in parallel and side by side and a plurality of reaction grooves for forming the reaction grooves are formed in parallel and side by side in the one surface of the base plate while a plurality of second inlet grooves for forming the second inlet paths are formed in parallel and side by side in the other surface of the base plate; and a plurality of junction holes for forming the junction channels are so formed as to penetrate the base plate from the one surface to the other surface between the corresponding ones of the respective first and second inlet grooves and the reaction grooves corresponding to the inlet grooves so that the junction holes connect downstream ends of the inlet grooves and upstream ends of the reaction grooves, wherein each of the first inlet grooves has a linear portion extending from the downstream end of the first inlet groove to an upstream side of the first inlet groove, each of the second inlet grooves has a linear portion extending from the downstream end of the second inlet groove to an upstream side of the second inlet groove, and the linear portions of the first inlet grooves are arranged parallel to the linear portions of the second inlet grooves, and the linear portions of the paired first and second inlet grooves are arranged side by side in a thickness direction of the base plate.
