Abstract: Proposed is a reformed zeolite and a catalyst composite using the reformed zeolite which have improved heat resistance and are used in a selective catalytic reduction (SCR) catalyst using ammonia or urea as a reducing agent, in a filter-type selective catalytic reduction (SDPF) catalyst in which a filter is coated with the SCR catalyst, or in a lean nitrogen oxide diesel oxidation catalyst (NA-DOC). In the reformed zeolite and the catalyst composite, alumina components, which are a zeolite coating material, improve heat-resistance of the zeolite and promote catalytic efficiency in a high-temperature condition.

Abstract: The present invention relates to zeolite containing Cu2+ (?) and Cu2+ (?) having different NO adsorption capacities loaded at a specific ratio, wherein the zeolite is chabazite (CHA)-type zeolite, particularly chabazite (CHA)-type zeolite loaded with divalent copper ions in which the NO adsorption area ratio of Cu2+ (?)/Cu2+ (?) after exposure to NO (nitrogen oxide) for 180 sec is 80% or more. In addition, the present invention relates to a method of preparing zeolite that is ion-exchanged in a slurry state and to a catalyst including the specified chabazite (CHA)-type zeolite.

Abstract: A method and apparatus for controlling the brightness of an image processing device to improve a brightness characteristic of an image signal, by reducing a pedestal voltage range and correspondingly expanding a brightness control voltage range in a highlight mode. The brightness control method includes the operations of determining whether a highlight mode is enabled; and if the highlight mode is enabled, reducing a pedestal voltage range by a first predetermined value and expanding a brightness control voltage range by a second predetermined value. The pedestal driving voltage and the brightness control voltage can be reciprocally controlled without modifications to a circuit having limited amplification, and the brightness can be improved without saturating an image in a highlight mode.
