  • Patent number: 10087093
    Abstract: A fluid treatment apparatus for treating a target fluid is provided. The fluid treatment apparatus includes a cylindrical reactor and one or more catalyst members each having a rod-like or plate-like shape extending in a longitudinal direction within the reactor. The cylindrical reactor decomposes an organic substance contained in a mixed fluid of the target fluid with an oxidant by an oxidation reaction under heat and pressure. The cylindrical reactor has an introduction port on one end and a discharge port on the other end. An upstream end surface, relative to a direction of flow of the target fluid, of each of the catalyst members is located in a downstream vicinity of or upstream from an inflow position where the target fluid flows into the reactor through the introduction port. Each of the catalyst members is suspended with the upstream end surface being fixed.

  • Publication number: 20150368129
    Abstract: A fluid treatment apparatus for treating a target fluid is provided. The fluid treatment apparatus includes a reactor to decompose an organic substance contained in a mixed fluid of the target fluid with an oxidant by an oxidation reaction. The reactor includes a cylindrical base material, a catalyst, and a migration space. The catalyst accelerates the oxidation reaction of the organic substance, and is disposed along an inner periphery of the cylindrical base material. Into the migration space, solids precipitated in the oxidation reaction migrate in a longitudinal direction without accumulating.
