摘要： PROBLEM TO BE SOLVED: To provide a reaction tank for fixing carbon dioxide that a filter to be set as a catalyst placing shelf at the bottom of a tray of the reaction tank is prevented from being clogged. SOLUTION: A catalyst 8 filled in a tray 18 in a reaction tank 12 is heated to 400 to 700 deg.C by a heater 19 of a heating furnace 20, and a reaction gas is introduced from a gas flow inlet 16a provided at the lower part. Glass wool 14 provided at a shelf 15 of the lower part of the tray 18 and being sandwiched between nets 13a, 13b from the upper and lower sides is used as a filter of a catalyst placing shelf. A reaction gas is allowed to uniformly diffuse in a space of a cylinder 24 and to pass through the glass wool 14 and subjected to reduction reaction on the catalyst, thereby carbon dioxide is fixed. After reaction for a prescribed time, a cap 25 is opened and the tray 18 is taken out to the outside, and thereafter the fixed carbon 7 is separated from the catalyst 8.

摘要： PROBLEM TO BE SOLVED: To provide a reaction tank for fixing carbon dioxide that it is not necessary to take a tray out of the reaction tank to the outside every time in order to separate fixed carbon on the surface of a catalyst. SOLUTION: A catalyst 8 is filled in a tray 18 in a reaction tank 12 and a reaction gas is introduced from a gas flow inlet 16 provided at the lower part. The catalyst is heated to 400 to 700 deg.C by a coil heater 19 of a heating furnace 20. Fixed carbon deposits on the surface of the catalyst 8 from the reaction gas by catalytic reaction. After reaction, a crusher 1 provided at the upper part is lowered downward by a motor 2 with a stroke controller 5, the rotating speed is controlled by a rotation speed controller 4 and the crusher is rotated to agitate in the catalyst, thereby the fixed carbon is separated. Thereafter, the fixed carbon is recovered from a gas outlet 16b provided at the upper part by sending a carrier gas having a high flow rate into the reaction tank 12 from the lower part by a carrier gas sending mechanism 27.

摘要： PROBLEM TO BE SOLVED: To provide a reaction tank for fixing carbon dioxide that a catalytic reaction in the reaction tank can be observed from the outside. SOLUTION: A transparent quartz reaction tube 1 in which a catalyst 8 is filled is provided at the inside of a coil heater 2, and a reaction gas comprising carbon dioxide and methane or hydrogen is introduced from a gas flow inlet 5 provided at the lower part and the reaction gas is heated to 400 to 700 deg.C by the coil heater 2. At the inside of a quartz protecting tube 3, a gold plated thin film 4 for reflecting and insulating heat rays and a slit 10 free from the gold plated thin film are formed. Thereby, the temperature and the flow rate of the reaction gas can be controlled while observing whether the reaction of the reaction gas is proceeding at suitable temperature and flow rate of the gas or not, through the slit free from the gold plated thin film, so that the catalytic reaction can be efficiently carried out.

摘要： PURPOSE:To have precision temp. control by furnishing a rotary insulation retaining a thermo-sensor at the wall of an insulative cylinder in such a way as rotatable, and thereby enlarging the insert depth of the thermo-sensor. CONSTITUTION:An insulative wall 20 is arranged inside a furnace shell 10 as an insulating cylinder in which a heater 30 is incorporated, while a rotary insulation 40 is installed rotatably in a notch 21 of this insulative wall 20 and retains a thermocouple meter 50 to sense the low range temp. in the furnace, and further a motor 60 is installed at outside lower part of the furnace shell 10 to rotate the rotary insulation 40. In case the interference temp. is in the operating range of the thermocouple meter 50, it is situated inside the furnace shell 10, and when the interference temp. transfers into the operating range of a radiative thermometer 90, the motor 60 is put in operation to move the thermocouple meter 50 to outside the insulative wall 20. When thereafter the interference temp. sinks from the operating range of the radiative thermometer 50 again to the operating range of the thermocouple meter 50, the motor 60 is operated to move the thermocouple meter 50 to inside the insulative wall 20.

摘要： PURPOSE:To thoroughly eliminate the danger of an explosion accident in the discharge line of a heat treatment furnace by admitting an inert gas into an upper stream side discharge line communicating the heat treatment furnace and a vacuum pump and a down stream side discharge line communicating with the discharge port of the vacuum pump. CONSTITUTION:The 1st inert gas supply line 11 is connected, near the discharge port 5b of the vacuum pump 5, to the down stream side discharge line 7 which communicates with the discharge port 5b and has an atm. releasing port 8 at the other end. The inert gas such as N2 is introduced via the 1st valve 12 into the down stream side discharge line 7. The upper stream side discharge line 6b between a main valve 9 and the suction port 5a of the vacuum pump 5 is communicated with the 2nd inert gas supply line line 13 branched from the 1st inert gas supply line 11. The 2nd valve 14 is opened or closed to admit the inert gas into the upper stream side discharge line 6b at a prescribed timing. The generation of the explosion accident by mixing of an explosive gas and oxygen in the discharge line during the operation of the vacuum pump 5 is thereby prevented.

摘要： PROBLEM TO BE SOLVED: To conserve heat energy as the heating source of a reaction tank. SOLUTION: A radiant tube 3 is wound around the outer periphery of a reactor 4 housing a catalyst 5 and methane being a part of reaction gas or hydrogen capable of decomposing methane is burnt by a gas burner 6 and the combustion gas 11 of the gas burner is sent to the radiant tube 3 to be used as a heating source. Carbon dioxide/methane reaction gas 8 is introduced into the reaction tank 1 from a gas introducing port 12 provided to the lower part of the reaction tank 1 and fixed carbon 10 is formed on the surface of the catalyst 5 by catalytic reaction. The gas after reaction and the combustion gas 11 are discharged to the outside from an exhaust pipe 13 provided to the upper part of the reaction tank 1 to be circulated. If reaction is stabilized, only an electric heater is used in heat insulation by little power.

摘要： PROBLEM TO BE SOLVED: To provide an apparatus for fixing carbon dioxide, having high fixation efficiency by reacting carbon dioxide with hydrogen in the presence of a catalyst. SOLUTION: Carbon dioxide 1 is mixed with hydrogen 3 and nitrogen 2 in a tank 4. The mixed gas is sent to a reaction system by a valve 5 and a pump 6. The gas is sent to a spiral pipe 10a of a heat exchanger 10 by a flow rate control valve 7, a pump 8 and a flow meter 9, preheated, brought into contact with a catalyst 12 heated to a fixed temperature by a heating furnace 11a of a reactor 11 to reduce the carbon dioxide with the hydrogen 3 into carbon and steam. The gas after the reaction is passed through a pipe 11b arranged at the center of the reactor 11, supplied to the central part of the heat exchanger 10, sent from the outer peripheral part of the heat exchanger 10 to a reversed U-shaped pipe 13a of a condenser 13, condensed by cooling water 15 into drain, which is stored in a tank 14. The gas discharged from the condenser 13 is sucked in the pump 8 again and the reaction is repeated in the same gas circulation loop.

摘要： PURPOSE:To prevent a compact from being deformed or adsorbing moisture, etc., by transiently transforming a green body into an intermediate tentatively called 'a yellow body' in the physically stabilized region. CONSTITUTION:A green body obtained by compacting a mixture of powder and binder is kept at a temp. where a part of the low-mol.wt. component bL in the binder B is melted at atmospheric pressure and the green body is not softened or gradually heated and heat-treated, and an yellow body W(Y), in which the high-mol.wt. component bH is locallized in the green body, is obtained. The component bH is reticularly bundled in the yellow body, and the shape of the compact is held over a wide range by the bundles. Accordingly, even if the component bL is then melted and vaporized when the compact is degreased, sagging is effectively prevented. Meanwhile, since the yellow body is degreased only by several wt.% and the powder surface is covered with the binder, the oxidation of powder and adsorption of moisture is effectively obviated.
