摘要： PROBLEM TO BE SOLVED: To provide a reformer, having high reforming efficiency and superior durability, which eliminates a trouble of thermal expansion of structural components caused by combustion heat by separating a combustion layer and a reform layer. SOLUTION: In a container H, a plurality of flat tubes 3 are installed in parallel at a prescribed distance. Space inside of the flat tubes 3 is a combustion layer 1, and space formed in between flat tubes 3 is a reform layer 2. By installing an expandable and contractible bellows 5 at the end of the container H on the exit side of gas flow, expansion of flat tubes 3 caused by thermal expansion is absorbed, stress is mitigated and durability of the reformer is improved.

摘要： PURPOSE:To contrive decrease in energy consumption by partially heating a catalyst support through a process of providing a partial heating part connected to the catalyst support so as to be partially electrified. CONSTITUTION:A metallic support 15 wherein a short-circuit passage 22 in the radial direction is formed is attached in the position of a first catalyst device 11 of a catalyst device 10, and only the metallic support 15 is connected to the power supply such as a battery. The short-circuit passage 22 is formed on the end surface on the upstream side, and electric resistance of the short-circuit passage 22 is smaller than that of a band-like body for constituting a honeycomb-like column 20, so large current flows to the short-circuit passage 22. Accordingly, the short-circuit passage 22 becomes a live to build a fire even in the relative narrow range, and action of the catalyst is started near there, and the reactive heat heats the other catalyst material, so as to raise the temperature successively, thereby the catalyst is activated. Thereby, warming of the whole of the catalyst device 10 is achieved in a short period by electric power smaller than the conventional one. Accordingly, the whole of the catalyst device 10 quickly and normally purifies exhaust gas after an engine is started, the discharging time of not purified exhaust gas is shortened, and the amount of contaminant is decreased.

摘要： PROBLEM TO BE SOLVED: To provide a reformer capable of warming up in a short time when starting up, preventing catalyst degradation. SOLUTION: The reforming catalyst layer 3 is prepared in the tubular vessel 2. A reforming reaction takes place by introducing a reforming source gas into a gas introducing path 23 prepared in the upstream of the reforming catalyst layer 3. A supplemental air nozzle is installed in the gas introducing path 23, and air is introduced. Necessary heat is obtained by burning a portion of the reforming source gas. A warm-up supporting air nozzle 5 is operated when warming-up to feed air to the under pant of the reforming catalyst layer 3 where the condensed steam accumulates and becomes low temperature from the other parts, and to activate the catalyst early by generating heat.

摘要： PROBLEM TO BE SOLVED: To provide a reforming apparatus in which a water gas shift part is miniaturized as the catalytic performance enough to control the concentration of CO in a reformed gas to a prescribed value is maintained with a simple structure and which is suitable for an on-vehicle equipment and has excellent practicability. SOLUTION: In the reforming apparatus having a hydrocarbon reforming section 1, a water gas shift section 2 and a selective oxidation reaction section 3, a catalyst in the water gas shift section 2 is separated into a pre-stage shift catalyst C1 and a post-stage shift catalyst C2 and a heat exchanger 5 is provided therebetween. The reaction quantity of CO is increased by increasing the temperature of the reformed gas to be introduced into the pre-stage shift catalyst C1 and the concentration of CO is further reduced by cooling the gas to be introduced into the post-stage shift catalyst C2 with air or water passing through the heat exchanger 5 to change the equilibrium and as a result, the apparatus is miniaturized.

摘要： PROBLEM TO BE SOLVED: To lower soot ignition temp. and to enable the combustion of particulates PM at the temp. of exhaust gas by using an exhaust gas purifying catalyst composed of a specific spinnel type composite oxide. SOLUTION: As this catalyst, a spinnel type composite oxide represented by general formula, AB2 O4 (wherein A is a transition metal capable of taking a bivalency in an oxidized state and at least one of Fe, Co, Ni, Cu, Zn, Cd, Pt and Hg and B is Ce) is used. By using this spinnel type composite oxide as a catalyst, soot ignition temp. can be lowered. This mechanism is considered to be generated because the difference between the electron state of a spinnel structure and an electron state peculiar to an element, especially, an electron state at a time when Ce is sued as B exerts effect on soot ignition temp.

摘要： PURPOSE:To achieve rapid catalytic activation, with least effects of thermal deterioration and poisoning in spite of long-time use in the structure of a catalyst carrier which is so designed as to allow a partial shortcircuiting of metal foils and consequent partial heating. CONSTITUTION:The energized thermal metal catalyst carrier structure is composed of an insulating layer 4 formed on metal foils constituting a catalyst carrier for electric insulation. In this structure, the insulating layer 4 on a downstream side from an end 6 located on the upstream side of an exhaust current in an assembled form, is partly removed, and in this removed part, metal foils are allowed to shortcircuit with each other. When this carrier is used, an electric current concentrates in this shortcircuited part which in turn, becomes heated. However, this part which is not an area subjected to thermal deterioration or poisoning, does not show any deteriorated activation efficiency, even if used for long time.

摘要： PURPOSE:To make the shift in an axial direction hard to generate and to easily obtain strong bonding by bonding thin plates adjacent to each other in a raw plate state when a current supply heating type catalyst device is produced. CONSTITUTION:In the corrugated plate 1 and flat plate 2 wound around a center electrode 4, the parts corresponding to a center bonding region 3a and an outer peripheral bonding region 3b are raw plates 1a, 2a and a region 3c consists of plates 1b, 2b each having an insulating film formed on the surfaces thereof. At first, the corrugated plate 1 and the flat plate 2 are produced to be wound around the center electrode 4 and, thereafter, the bonding regions 3a, 3b are bonded by edge discharge processing welding. Since the flat plate 2 and corrugated plate 1 of this bonded region are raw plates, extremely high welding strength is easily obtained.
