摘要： PURPOSE:To obtain a catalytic honeycomb shaped product which provides a sufficient activity at high temperature and maintenance strength by limiting the specific surface area of a combustion catalytic element manufacturing using a substitution-type laminated aluminate as a raw material to a specified range. CONSTITUTION:A substitution-type laminated aluminate is used as a raw material, and the specific surface area of a combustion catalytic product manufactured by molding said aluminate is 2m /g or more to 24m /g or less. Of the specific surface area is specified as 2m /g or more to 24m /g or less, a satisfactory combustion rate is obtained. In addition, if the specific surface area is 24m /g or less, the catalyst has an adequate strength to withstand its use as a honeycomb shaped product. Subsequently, an activity at high temperature is obtained and the high strength of the catalytic honeycomb shaped product is ensured.

摘要： PURPOSE:To enable high activity to be maintained for an extremely long time without activity deterioration by depositing a honeycomb structure of manganese substitution-type laminated aluminate of specific composition in the inner stream of an inlet. CONSTITUTION:In a catalyst for high temperature combustion of a fuel gas and air mixture, the first catalyst with a catalytic component such as lanthanum carried by a heat-resistant honeycomb element consisting mainly of palladium is deposited on the mixture inflow side. In the stream after the first catalyst, the second catalyst with a specific composition of a honeycomb-structured manganese substitution-type laminated aluminate is deposited. The catalyst thus obtained makes possible stable catalytic combustion at about 1000 to 1300 deg.C.

摘要： PURPOSE:To obtain the apparatus which is compact and has an excellent thermal efficiency, and is allowed to control the generating quantity of reformed gas to be optional one by joining combustion gases generated in each hydrocarbon reformer in a fire-resisting and heat-insulating hausing and then discharging. CONSTITUTION:The flow passage of combustion gas (A) formed in the clearance between a rising pipe and a inner pipe 5 in each of reformers A-G is opened at the top end side of reaction pipe 2 into the inner part of the housing 1. The combustion gas (C) flowing out of the opening part flows through the space S packed with heat transmitting packing as a common flow passage in the housing 1 while heating each reaction pipe 2, 2,... from the outside of each outer pipe 6, 6,..., and is discharged through an exhaust gas discharge pipe 13. The raw material gas (A) introduced through a raw material gas pipe XI is branched into each raw material gas supplying pipe 11, 11,..., and then flows through each reaction pipe 2, 2,... while being heated with the combustion gas (C) to be reformed, and the reformed gases from each reformed gas taking- out pipe 12, 12,... are joined together in a reformed gas pipe XII to be discharged.

摘要： PURPOSE:To reduce temperature of a producer wall and suppress the amount of generated carbon, by annularly providing blowing nozzles between a combustion burner of a reducing gas producer and the inner surface of the producer wall and enabling a cooled recycle gas to blow therefrom. CONSTITUTION:Blowing nozzles 16 are provided between a combustion burner 15 of a gas producer 1 and the inner surface 9 of the producer wall. A hydrocarbon based fuel is incompletely burned in the above-mentioned gas producer 1 to provide a mixed gas containing hydrogen and carbon monoxide. A recycle gas obtained by partially cooling the mixed gas is fed through a recycle gas passage 24 into the aforementioned blowing nozzles 16. A cooling layer is formed between a combustion flame and the inner surface 9 of the producer wall to reduce the temperature of the inner surface 9 of the producer wall.

摘要： PURPOSE:To prepare the title gas rich in CO through easy and accurate regulation of H2/CO ratio, by incomplete combustion of a hydrocarbon fuel contg. CO2 and steam added thereto within a gas generator. CONSTITUTION:A mixed gas prepd. by feeding steam from a supply pipe 30 into CO2 contained in a supply pipe 28 is added to a hydrocarbon fuel (e.g., C6H6) contained in a supply pipe 29, thereby preparing a mixed fuel. The fuel thus prepd. is introduced into the inside 7 of a gas generator 1 through an inner pipe 12 while O2 is introduced thereinto as a combustion improver through an outer pipe 13, where the fuel is burned, thereby preparing a mixed gas mainly composed of H2 and CO. The mixed gas is discharged from an exhaust passage 5, and the heat is removed therefrom in a waste heat boiler 20. Then, the moisture is removed therefrom in a scrubber 21, and dust is removed therefrom with a dust collector 23. The pressure of the treated gas is raised with a compressor 24, and CO2 is separated in a CO2 absorber 26, thereby preparing a gas product. On the other hand, CO2 separated in the absorber 26 is purified in a CO2 stripper 27 and then circulated in a supply pipe 28.

摘要： PURPOSE:To stabilize smelting and reduction operation by prereducing iron ore to a specified rate of metallization in a prereducing furnace, adding iron ore as starting material to the resulting reduced iron discharged from the prereducing furnace and charging them into a smelting and reducing furnace. CONSTITUTION:Iron ore 16 is prereduced in a prereducing furnace 3, introduced into a melt reducing furnace 1 and smelted and reduced to manufacture iron. At this time, hot exhaust gas 7 produced by secondary combustion in the smelting and reducing furnace 1 is introduced into a gas modifying equipment 8 to regulate the temp. of the gas as well as to modify the gas with gaseous hydrocarbon 9 and the modified gas is added to part of exhaust gas 10 from the prereducing furnace 3 and introduced into the furnace 3. The iron ore 16 is prereduced to >=90% rate of metallization in the furnace 3 and the resulting reduced iron discharged from the furnace 3 is introduced into the smelting and reducing furnace 1 after iron ore 18 as starting material is added to the reduced iron.

摘要： PURPOSE:To obtain a lamellar catalyst having a uniform thickness distribution by extruding coaxially a slurry contg. a catalyst and a carrier or the like on a supporter such as a pipe and a rod, drying it to make a ring-shaped green body and opening it to make a lamellar shape. CONSTITUTION:In relation to a lamellar catalyst used for a reforming type fuel cell or the like, both a slurry 11 contg. a catalyst, a carrier and an aid catalyst, if necessary, and a supporter 12 such as a pipe and a rod are inserted into a vessel or an extruder provided with a mouthpiece having a prescribed shape and this supporter 12 is coaxially extruded from the mouthpiece having the prescribed shape together with the slurry 11 while sticking the slurry 11 on the supporter 12. A ring-shaped green body is obtained by heating the ring- shaped slurry on the supporter 12 and a lamellar green body is obtained by opening it in the extrusion direction on the supporter 12 and developing it. In such a way, the lamellar catalyst having a regular thickness distribution in accordance with the mouthpiece shape is obtained.
