摘要： PURPOSE:To efficiently generate high-purity gaseous oxygen by providing a porous anode fitted with a porous water-retentive material to one surface of a solid high molecular electrolytic material and feeding water to the cathodic chamber of a porous cathodic side which is provided to the other surface thereof and electrolyzing it. CONSTITUTION:In the inside of an electrolytic cell 1, a porous anode 3 and a porous cathode 4 are provided respectively to both surfaces of a solid high molecular electrolytic material 2 such as a membrane of a perfluorocarbonsulfonic acid-base polymer. Furthermore a porous water-retentive material 11 consisting of a high-water absorptive high molecular material is fitted on the porous anode 3. Water or steam is fed to a cathodic chamber 6 faced with the porous cathode 4 through an inlet 8 of water supply. Then water is electrolyzed by impressing electric power to both electrodes 3, 4 from a DC electric source 7. Gaseous hydrogen generated in the cathodic chamber 6 by electrolysis is collected through an outlet for the produced gaseous hydrogen. On the other hand, the steam contained in oxygen generated on the anode 3 is trapped to the water-retentive material 11 and electrolyzed on the anode 3 and high-purity gaseous oxygen is recovered through the outlet 9 for the produced gaseous oxygen.

摘要： PURPOSE:To obtain a catalyst for decomposing methane gas by using a heat- resistant fiber as the catalyst carrier and platinum group metal as the active catalyst component, and depositing the platinum group metal on the heat- resistant fiber. CONSTITUTION:Silica wool, alumina wool or carbon fiber is used as the catalyst carrier, on which platinum, ruthenium, iridium or paradium is deposited as the active catalyst component by plating (chemical plating, electroless plating, electrolytic plating) or by vapor deposition method (CVD, PVD). By using this catalyst as the catalyst for decomposing methane gas, the collected amt. of precipitated carbon can be increased and the weight of the carrier itself can be decreased with larger specific surface area. Since the interval of changing the catalyst can be extended about twice, the electric power required for the cycle of heating and cooling the methane decomposing furnace can be reduced.

摘要： PURPOSE:To obtain a methane gas-thermal decomposition method with an apparatus whose size is reduced to 1/2 by putting a catalyst consisting of a support (alumina support) and ruthenium carried on the support in a uniformly heating part of a methane gas-decomposition furnace and supporting both ends of the catalyst with a heat-resistant fiber. CONSTITUTION:A catalyst (ruthenium catalyst) B consisting of alumina and about 0.5% of ruthenium carried on the alumina is packed in a uniformly heating part of a reaction tube A and silica wool C is packed in both side of the catalyst to hold the ruthenium catalyst B. Methane gas is led by a mass flow meter D to the reaction tube A, pre-heated about 1000 deg.C after the reaction system is purged by nitrogen gas. After a specified amount of methane gas is led to replace the gas in the reaction tube by methane, the pressure of the system is set to be about 0.5kg/cm G (gauge pressure) by a backing pressure valve E. In this way, methane gas is decomposed. By this method, the decomposition temperature is able to be set low, and thus it is possible to make the size of the apparatus about 1/2.

摘要： PURPOSE:To conserve heat energy at the time of the desorptive recovery of CO2, by communicating a plurality of adsorbing tanks by a recirculation means and transferring the heat of one heated adsorbing tank to the other adsorbing tank heated later by said recirculation means. CONSTITUTION:Air is guided to an adsorbing tank 1 to adsorb CO2 and the adsorbent in an adsorbing tank 2 is regenerated under heating while CO2 is cooled by a cooler through a connection line and recovered by the venting of air through a valve. When both processes are respectively finished, the heat of the high temp. adsorbing tank 2 is transferred to the low temp. adsorbing tank 1 through a heat source recirculation line 21 and, when both tanks are brought to almost same temp., the adsorbing tank 2 is cooled by a cooling medium line 6 through a cooler 25 to prepare the adsorbing process. When cooling is completed, the adsorbing tank 2 enters the adsorbing process and, in the adsorbing tank 1, the recovery of CO2 by heating is performed.

摘要： PURPOSE: To provide a method for economical degreasing cleansing which prevents the ozone layer from being destroyed, prevents an oil from adhering to a material to be washed and presents no danger of flammability. CONSTITUTION: A washing tank 5 is cleansed with a washing solution 3 obtained by adding 10-20% water in a weight ratio to a glycol ether-based detergent. The washing solution 3 is allowed to overflow from the washing tank 5, to remove an oil in the washing solution. The soiled washing solution is put under a reduced pressure in a vacuum distiller 8 to distill the glycol ether-based detergent for reuse.

摘要： PURPOSE:To provide an electric oven for the decomposition of CH4, capable of uniforming anchoring the decomposition-produced C on a catalyst to reduce the exchange frequency of the catalyst, and a method for decomposing the CH4. CONSTITUTION:A catalyst comprising an alumina wool carrier carrying an iron catalyst is placed in an electric oven. The catalyst is divided into three temperature-controllable compartments 5, 6, 7. CH4 to be decomposed is charged from the right side of the drawing, and from the left side the decomposition- produced H2 is flown out. The temperatures of the temperature-controlled compartments 5, 6, 7 are 950 deg.C, 1000 deg.C and 1050 deg.C, respectively, and a large amount of the decomposition-produced C is anchored on the high temperature compartment. A prescribed time later, the temperatures of the compartments are kept at 1000 deg.C to deposit the most amount of the decomposition-produced C in the compartment 5 on the side of the CH4 inlet, thus finally uniformly anchoring the decomposition C on the catalyst.

摘要： PURPOSE:To improve the efficiency of decomposition reaction of carbon dioxide gas and to enable the reduction of overall volume of the reactor, by passing a mixture of carbon dioxide gas and hydrogen through a zone filled with a carbon dioxide gas decomposition catalyst and having two different temperature zones. CONSTITUTION:Carbon dioxide gas is decomposed into carbon and water with hydrogen using the following process. A mixed gas 1 composed of carbon dioxide gas and hydrogen is supplied to a zone 3 filled with a carbon dioxide gas decomposition catalyst and having two different temperature zones. The carbon dioxide gas is decomposed into carbon monoxide and water in the 1st temperature zone (a zone heated with a heater 5) and the carbon monoxide generated in the 1st temperature zone is decomposed into carbon and water in the 2nd temperature zone (a zone heated with a heater 6). The catalyst is e.g. a wire catalyst made of Fe or Ni.

摘要： PROBLEM TO BE SOLVED: To provide a washing device for pipes having excellent washing capability without using a 1.1.1-trichloroethane which is said to be the cause for the destruction of the ozone strata. SOLUTION: A washing basket 13 is immersed in a washing tank 10 in which an aq. alkaline washing liquid 11 is housed. This washing basket 13 is provided with a force feed tank 14 and the pipes 1 to be washed are housed into the washing basket 13. These pipes 1 are connected at one end to the force feed tank 14. The aq. alkaline washing liquid 11 is lifted by a washing liquid supply pump 24 and is supplied to the force feed tank 14 so that the aq. alkaline washing liquid 11 is made to flow along the inside and outside surfaces of the pipes 1. The stains sticking to the inside surfaces and outside surfaces of the pipes to be washed are eventually removed by the cooperation of the chemical reaction effect of the aq. alkaline washing liquid and the friction peeling effect by the flow, by which the washing of the inside and outside surfaces of the pipes is well executed.
