になる欠点があつた。 BACKGROUND ART Conventionally, in order to oxidize and decompose gases such as organic solvents, hydrocarbons, and ammonia, catalysts supported on pellet-like, linear, honeycomb-like, etc.-shaped supports have been used. In order to maintain these catalysts at their activation temperature (optimum decomposition temperature), the catalyst temperature has been indirectly controlled by controlling the temperature of the gas before or within the catalyst layer. However, such conventional heating or cooling bodies require considerable space, making the catalyst device large and complex.
Another disadvantage is that the temperature within the catalyst layer rises along the flow direction due to the heat of decomposition of the gas decomposed by the catalytic action, making the operation of controlling the catalyst to the activation temperature extremely complicated.

It is characterized by the combination of these features.

導入パイプおよび媒体排出パイプである。 FIG. 1 is a partially cutaway perspective view of a catalyst-carrying finned pipe. A thin film of aluminum oxide (Al 2 O 2 ) is formed by a method such as treatment or sintering of alumina, and a catalyst is further supported on the thin film to form the catalyst element of the catalyst-carrying finned pipe 4 . The catalyst used herein refers to one or a combination of two or more of platinum, palladium, rhodium, iron oxide, and the like. A cooling medium such as water, steam, or an organic medium is caused to flow through the pipe of the catalyst-carrying finned pipe 4 to control the catalyst to an active temperature. Such a catalytic element may be a continuous unit itself or may be an assembly of several independent elements, and may be used appropriately depending on ease of temperature control, ease of manufacture, etc. good. In addition, instead of flowing a cooling medium through the pipe, the catalytic element is made into a closed container containing a small amount of working medium such as water, alcohol, or organic medium, as shown in Figure 2, to improve the thermal uniformity of the heat pipe and Temperature control may be performed using thermal conductivity. Such a catalyst-supported heat pipe 5 is a heat transport element that utilizes the latent heat of the working medium, and can transport heat very efficiently.
FIG. 3 is a schematic diagram showing a catalyst device incorporating the catalyst element of the catalyst-carrying finned pipe 4 as described above as a catalyst layer. In FIG. 3, a plurality of catalyst-carrying finned pipes 4 are connected by a joint pipe 6, and this is installed in a box to form a catalyst layer 10. Note that 8 and 9 are a medium introduction pipe and a medium discharge pipe, respectively.

It becomes easy to maintain and adjust. Additionally, since the catalyst temperature is directly controlled, there is less energy loss and energy savings compared to conventional indirect catalyst temperature control methods.

Next, the pipe with fins treated with aluminum oxide in this way is immersed in a 2% aqueous solution of platinum complex using chloroplatinic acid, and then pulled out and subjected to hydrogen reduction at about 500°C to form a pipe with platinum-supported fins on which platinum is supported. I got pipe 4. This platinum-supported finned pipe 4 constitutes a catalyst layer 10 as shown in FIG.
