Abstract:
1. A fine channel device comprising: a fine channel provided with first and second inlet ports configured to feed fluid; a fluid containing a catalyst disposed in the fine channel device; first and second inlet channels communicated with the first and second inlet ports, respectively, wherein the fluid containing a catalyst flows from the first inlet port to the first inlet channel; a confluent portion communicated with the first and second inlet channels; a branch portion communicated with the fine channel, from which first and second outlet channels are branched and configured to feed predetermined amounts of fluid; first and second outlet ports communicated with the first and second outlet channels, respectively; and a circulating channel configured to feed the fluid containing a catalyst discharged from the first outlet port to the first inlet port, wherein the fine channel includes a plurality of partition walls disposed along a boundary formed by at least two kinds of fluid fed from the inlet ports configured to not cause mutual contamination of fluid, wherein each partition wall of the plurality of partition walls includes an elongated upper edge that extends along a line parallel to a fluid flow path within the fine channel, wherein the plurality of partition walls are disposed at intervals in a flowing direction of fluid, said intervals are longer than an elongated length of each partition wall, wherein intervals between the partition walls are present along the entire length of the fine channel except in the vicinity of the confluent portion and the vicinity of the branch portion of the fine channel, and wherein the partition walls include continuous partition walls disposed in the vicinity of the confluent portion and in the vicinity of the branch portion of the fine channel, and wherein a thermal barrier is disposed between the confluent portion and the branch portion.
