摘要： PROBLEM TO BE SOLVED: To supply hydrogen produced by decomposition of hydrogen resources such as ammonia, and to utilize an exhaust gas from a fuel cell for preventing hazardous substance releasing by.
SOLUTION: An hydrogen producing apparatus is composed of a decomposer 2 in which the hydrogen resources are decomposed to nitrogen and hydrogen and to supply them to the fuel cell, a combustor 3 to combust the exhaust gas from the fuel cell 4 by a catalytic reaction, air feeding means 5 to feed combustion air to the combustor 3, an oxygen sensor 34 to measure oxygen concentration in the exhaust gas from the combustor 3 and a controller 6 to control the air feeding means 5. As the hazardous substance such as ammonia in the exhaust gas from the fuel cell is combusted and removed in the combustor 3, the releasing of the hazardous substances can be prevented. When heat from the combustor 3 is fed to the decomposer 2, energy efficiency is improved because a heat source to heat the decomposer 2 is not required.

摘要： PROBLEM TO BE SOLVED: To provide a hydrogen production method capable of manufacturing hydrogen in one reactor at a lower temperature and reducing a CO concentration in a reformed fuel gas below 100 ppm, preferably below 10 ppm. SOLUTION: A hydrogen conversion process and a regeneration process are performed by turns. The hydrogen conversion process consists of obtaining H2 by containing a mixed gas composed of a fuel and steam with a reaction layer containing a reforming catalyst and a carbon dioxide adsorption and adsorption auxiliary agent, while fixing by-produced carbon dioxide to a carbon dioxide adsorption and adsorption auxiliary agent. The regeneration process consists of regenerating the carbon dioxide absorption power of the carbon dioxide adsorption and adsorption auxiliary agent by eliminating the fixed carbon dioxide by heating the carbon dioxide adsorption and adsorption auxiliary agent. The most part of reforming fuel gas becomes only hydrogen due to suppression of bi-production of methane, since produced CO is converted into H2 and CO2 , and the CO2 is absorbed by the carbon dioxide adsorption and adsorption auxiliary agent, and fixed out of the equilibrium, and the restriction to restrict reaction temperature to 700-900 deg.C or above is released, since methane is not generated.

摘要： PROBLEM TO BE SOLVED: To precisely estimate CO/H2 concentration ratio in reformed gas by precisely estimating degree of deterioration of reforming catalyst, and to further improve fuel consumption and NOX purifying ability by adding the reformed gas to fuel or exhaust gas. SOLUTION: CO and H2O in additive gas are reformed to H2 and CO2 by watery gas shift reaction by a CO shift catalyst 4, the reformed gas is added to at least either of exhaust gas of an internal combustion engine and fuel of the internal combustion engine, and additive quantity of the reformed gas is controlled based on the CO/H2 concentration ratio in the reformed gas estimated based on oxygen storage capability (OSC) of the CO shift catalyst 4. Since an extremely high correlation exists between OSC of the CO shift catalyst 4 and watery gas shift reaction activity, the CO/H2 concentration ratio in the reformed gas can be estimated at high precision by detecting the OSC.

摘要： PURPOSE: To improve the purification factor, and to enlarge the A/F window by arranging a low-oxidation active zone upstream in the exhaust flow, and arranging a high-oxidation active zone downstream, and passing the exhaust in order between them. CONSTITUTION: The exhaust 19 is led into a low-oxidation active zone 11. In this low-oxidation active zone, NOX is mainly purified, and the low-oxidation active catalyst for restricting the oxidation reaction of CO, HC is carried. In the case where the exhaust 19 exists in the lean side due to the catalyst, NOX is purified. Next, after passing the low-oxidation active zone 11, the exhaust 19 is led into a high-oxidation active zone 12. Ordinary three dimensional catalyst is carried in the high-oxidation active zone 12. In the case where the exhaust 19 exists in the rich side, NOX, CO, HC, which can not be purified in the low-oxidation active zone 11, can be purified at a degree as same as the conventional technique.

摘要： PURPOSE:To control the thermal deterioration due to exhaust gas containing water by further ion-exchanging an alkali metal cation obtained by ion- exchanging ammonium ion in ammonium type zeolite, with a catalyst metal so that the catalyst metal is supported on the zeolite. CONSTITUTION:When ammonium ion in ammonium type zeolite is ion-exchanged with an alkali metal cation, the ammonium ion which causes the generation of Brphinsted acid points is replaced with the alkali metal ion. Since the alkali metal ion is monovalent, most ammonium ion is replaced by the alkali metal cation. Next, the alkali metal cation is further ion-exchanged with the catalyst metal so that the catalyst metal is supported on zeolite. Since the residual alkali metal ion is not hydrolyzed in the following burning process, the generation of the Brphinsted acid points can be controlled.

摘要： PURPOSE:To efficiently remove nitrogen oxide even in such a state that a reducing substance is absent or excessive oxygen is present by partitioning a first passage through which gas containing nitrogen oxide flows and a second passage through which hydrogen gas flows by an air permeable partition wall containing a reducing substance and transferring hydrogen gas to the first passage through the partition wall by pressure difference. CONSTITUTION:A first passage through which gas containing nitrogen oxide flows and a second passage through which hydrogen gas flows is partitioned by an air permeable partition wall containing a reducing catalyst and hydrogen gas is transmitted through the partition wall by pressure difference to be transferred to the first passage. As a result, even in such a state that the reducing substance is not sufficiently present or excessive oxygen is contained, nitrogen oxide can be efficiently removed.
