摘要:
An exhaust gas cleaner comprising a heat-resistant, porous filter, a porous ceramic layer formed on the filter, and a catalyst supported by the ceramic layer, the catalyst consisting essentially of:(a) at least one of alkali metal elements;(b) copper and vanadium; and(c) at least one of rare earth elements.By using this exhaust gas cleaner, particulate matter in the exhaust gas is oxidized by the catalyst supported by the filter, and nitrogen oxides are reduced by the particulate matter serving as a reducing agent.

摘要:
The method of cleaning an exhaust gas containing nitrogen oxides including disposing an exhaust gas cleaner comprising a heat-resistant, porous body, which may support a catalyst consisting essentially of (a) at least one of alkali metal elements; (b) at least one of elements selected from the group consisting of Cu, Co, Mn and V, (c) at least one of rare earth elements, in a flow path of the exhaust gas, spraying a liquid hydrocarbon into a stream of the exhaust gas on the upstream side of the exhaust gas cleaner, thereby causing atomized and gasified hydrocarbon to function as a reducing agent for reducing the nitrogen oxides in the exhaust gas.
摘要:
An exhaust gas containing nitrogen oxides and particulate matter is cleaned by using an exhaust gas cleaner including a heat-resistant, porous filter; a porous ceramic powder layer formed on the filter; and a catalyst supported by the ceramic powder layer, the catalyst consisting essentially of (a) at least one of alkali metal elements, (b) cobalt and/or manganese, (c) vanadium, and (d) at least one of rare earth elements, whereby the nitrogen oxides are reduced by the particulate matter in the exhaust gas serving as a reducing agent.

摘要:
An exhaust gas cleaner comprising (a) at least one filter made of a heat-resistant and electrically insulating material for trapping floating fine particles in an exhaust gas; and (b) at least a pair of electrodes stacked with the filter alternately, voltage being applied between the adjacent electrodes to burn electrically conductive and burnable fine particles trapped in the filter by heat generated by a current flowing between the adjacent electrodes, and the direction of the flow of the exhaust gas in the filter being essentially parallel to that of the laminate surface of the electrodes. The filter may carry a catalyst which functions to reduce harmful gas components in the exhaust gas.

The content recommendation system includes a user attribute information acquisition means for acquiring attribute information of a given user, a list acquisition means for acquiring at least one list from among lists of content sequentially generated over time on the basis of the attribute information of the given user acquired by the user attribute information acquisition means, a user preference information acquisition means for acquiring user preference information, which is feature information of content preferred by the given user, a content extraction means for extracting some content from content included in the list acquired by the list acquisition means on the basis of the user preference information acquired by the user preference information acquisition means, and a content presentation means for presenting the content extracted by the content extraction means to the given user.
摘要:
A switching hub, system and method for restricting a communication between terminals within a second network isolated form a first network. The terminals are connected to the first network or the second network, wherein a terminal with sufficient security level is connected to the first network and a terminal with insufficient security level is connected to the second network. And a communication between the terminals within the second network is restricted.
