Provided is a fuel-reforming catalyst that has excellent reforming activity and durability against deterioration factors such as catalyst poisoning and minimizes the amount of rhodium used. A fuel-reforming catalyst for reforming exhaust gas and a fuel containing a hydrocarbon into a syngas containing hydrogen, including a catalyst component and a carrier supporting the catalyst component, in which the catalyst component includes nickel, and the carrier contains a metal oxide including zirconium or cerium is provided.

Catalyst structure, fuel reforming method, and fuel reforming system

Provided is, for example, an exhaust gas-purifying three-way catalyst which is suppressed in particle growth due to sintering of a catalytically active component on a carrier in exposure to a high temperature and thus is enhanced in purification performance, and a method for producing the same, as well as an integral structure type exhaust gas-purifying catalyst using the same. The exhaust gas-purifying three-way catalyst of the present invention includes a composite particle which contains a base material particle having a pore size of 100 to 650 nm as measured by a mercury intrusion method and a catalytically active particle of a platinum group element supported on the base material particle, in which a content proportion of the catalytically active particle is 0.001 to 30% by mass in total in terms of metal of the platinum group element, based on a total amount of the composite particle.

A damper device set is provided which can mount a damper device on a door that is thin and has a constraint on the mounting position. A first fastening member is used to fix a mounting plate to a door. A second fastening member placed at a position different from the first fastening member in a thickness direction of the door is used to fix, to the mounting plate, a damper device including a case and a linear damper housed in the case. At least part of the linear damper overlaps at least part of the first fastening member in plan view of the door.

Described are catalysts effective to abate NO, hydrocarbons, and carbon monoxide from a gasoline engine exhaust gas. Such catalysts include a substrate having a first and second material disposed thereon, the first material effective to catalyze selective catalytic reduction of nitrogen oxides in the presence of ammonia and the second material effective to abate hydrocarbons and carbon monoxide, the first material comprising a molecular sieve promoted with copper and/or iron in a low loading, the second material comprising at least one oxide of Ni, Fe, Mn, Co, and Cu on a support selected from oxides of Ce, Ce&#x2014;Zr, Zr, Mn, Pr and combinations thereof. Also described are gasoline engine exhaust gas treatment systems and methods of treating exhaust gas from a gasoline engine.

Exhaust gas treatment catalysts

A system includes a free itemset generation unit to generate a set of free itemsets, each having a frequency in the database greater than or equal to a predetermined threshold value set in advance, a valid rule candidate generation unit to generate rule candidates and store the generated rule candidates, and a rule minimality decision unit to check minimality of each of the generated rule candidates and output the generated rule candidate to an output apparatus when the generated rule candidate is determined to be minimal.

Rule discovery system, method, apparatus, and program

A system includes a unit to generate a set of free itemsets with a frequency in a database greater than or equal to a threshold value, a unit to generate a rule candidate with, a conditional part set to the free itemset &#x3b1;, and a consequent part set to an item x not sharing an attribute with the free itemset, and finds a set of attributes of an antecedent part of the rule by depth first search, the attribute not included in neither &#x3b1; nor x, a unit to collate the rule to the database to judge validity of the rule, and a unit to check for minimality of the rule decided to be valid to output the rule when the rule is minimal.
