グ触媒の担体としては従来、その形状として球状。That is, the present invention uses a steam reformer that mixes hydrocarbons with water and reformes the mixture into inorganic gases mainly consisting of hydrogen and carbon dioxide using a steam reforming catalyst. By using a square or cylindrical integrally molded body, we aim to increase the activity of the steam reforming reaction, reduce pressure loss due to the catalyst, and facilitate the replacement of the catalyst. The purpose of this catalyst is to suppress carbon generated on the catalyst during the reforming reaction, and a basic substance such as dolomite or chromag is used as a catalyst carrier. Conventionally, integrally molded bodies having a honeycomb cross section or the like have been used only in a very limited range, such as for removing exhaust gas from automobiles. Conventionally, carriers for steam reforming catalysts such as those used in the present invention have been spherical in shape.

いる。An air supply pipe 10 through which gas, mainly inorganic gas such as carbon dioxide, passes is connected. The air supply pipe 10 is connected to a cooling pipe 11 and a gas-liquid separator 12 that separates excess water condensed and gas produced as a result of cooling. The separated gas is stored in a gas reservoir (not shown) and then used for various purposes. The front part of the reactor 1 is covered with a holding plate 13. The holding plate 13 is removable with bolts 14, so that a deteriorated reforming catalyst 8 can be replaced.

On the other hand, water is supplied to the passage 4 in the reactor 1 through the supply pipe 6 and then preheated by the heater 9. The hydrocarbon gas and steam preheated as described above are thoroughly mixed while passing through inorganic heat-resistant fibers 6 such as quartz wool, and then supplied to reforming catalyst 8 and reformed. Hydrocarbon gas and water are reformed and converted into inorganic gases, mainly hydrogen and carbon dioxide. The generated gas passes through the air pipe 10 to the cooling pipe 11

れた結果が得られた。The separated generated gas is stored in a gas reservoir (not shown) and used when necessary. Although the reaction is carried out as described above, if the reaction continues for a long period of time, carbon accumulates on the reforming catalyst 8, and the activity of the reforming reaction deteriorates. Regarding the tendency of carbon accumulation, it is well known that the greater the solid acid strength of the catalyst carrier, the greater the amount of carbon accumulation. Alternatively, it is well known that the amount of carbon accumulated can be reduced by adding an alkali metal or alkaline earth metal as a cocatalyst, and this has been put into practical use to some extent. In view of the above facts, the present invention uses a basic material such as dolomite or chromag as a catalyst carrier, and further uses the catalyst in an integrally molded body consisting of multilayer thin walls such as a honeycomb or lattice cross section. be. As a result, the following excellent results were obtained.
（１）アルミナ、シリカ等、従来用いられている固体酸
を触媒担体とした場合と比較しドロマイト、クロマグ等
の塩基性物質を触媒担体とした場合は、反応中に蓄積す
るカーボン量が非常に少くなった。この結果、触媒寿命
を大巾に延長する事が出来た。(1) Compared to the case where conventionally used solid acids such as alumina and silica are used as catalyst carriers, when basic substances such as dolomite and chromag are used as catalyst carriers, the amount of carbon accumulated during the reaction is much smaller. It has become less. As a result, we were able to significantly extend the catalyst life.
（２）断面が・・ニカム又は格子状の如き一体成形体を
触媒担体とした結果、次の利点が得られた。(2) As a result of using an integrally molded body having a nicam or lattice-like cross section as a catalyst carrier, the following advantages were obtained.
（１）圧力損失は、従来のビーズ状に比較し１／１００
程度となった。(1) Pressure loss is 1/100 compared to conventional beads
It became a degree.
（１１）同−Ｓ、Ｖ、 （空間速度）では、反応の活性
が増大し、その結果ガス速度を上げられＳ、Ｖ、が大き
く取れる。(11) At the same -S, V, (space velocity), the activity of the reaction increases, and as a result, the gas velocity is increased and S, V can be increased.
（ｉｉＤ 従来のピース触媒と異りガス流路がストレ
ートであり、流路内ガス流速が高速のためダスト付着が
少く、結果的に触媒寿命が長い。(iiD Unlike conventional piece catalysts, the gas flow path is straight and the gas flow rate in the flow path is high, so there is less dust adhesion, resulting in a long catalyst life.
Ｏｖ） 反応器自体をコンパクトにすることが出来た
