Claims

[Claims for Utility Model Registration] (1) A catalyst that causes an exothermic reaction upon contact with a target gas, a reaction vessel filled with the catalyst and having a section through which the target gas flows, and a reaction vessel filled with the catalyst. In a reactor having cooling pipes for cooling the catalyst installed in the compartments and a cooling medium flowing inside the cooling pipes, the cooling pipes are almost evenly distributed in the catalyst-filled compartments, and the target gas flows through the catalyst-filled compartments. A sleeve is provided to be loosely inserted into the cooling pipe in the section that flows into the compartment, and the length of the sleeve is shorter than the cooling pipe in the catalyst-filled compartment, and in the part where the sleeve is present, the catalyst is inserted between the sleeve and the cooling pipe. Only the cylindrical gap between the sleeves is filled, and the space between the sleeves is sealed to prevent the target gas from flowing in, and the cross-sectional area perpendicular to the flow direction of the target gas of the catalyst-filled compartment is
An isothermal reactor characterized in that the target gas inlet portion of the catalyst-filled compartment is smaller than the target gas outlet portion. (2) The isothermal reaction device according to claim 1, wherein the diameter of the sleeve changes depending on the position in the flow direction of the target gas. (3) A heat sink in which the cooling pipe has a condensing section in a section on the opposite side of the channel to the wall surface facing the catalyst-filled section of the channel on the target gas inlet side of the reaction vessel, and an evaporating section in the catalyst-filled section. Claim 1 for utility model registration characterized by being a pipe
The isothermal reaction device according to any one of items 1 to 2. (4) The cooling pipe is a double pipe extending from the surface of the channel on the target gas inlet side of the reaction vessel facing the catalyst-filled section to a position that does not reach the end face of the target gas outlet side of the catalyst-filled section. An isothermal reaction device according to any one of claims 1 to 2 of the utility model registration claims.
