A method for preparing a NOx storage catalyst includes preparing a synthetic mother liquid including a zeolite raw material as a source of silica and alumina, a structure-inducing material, a complexing material, and a solvent, reacting the synthetic mother liquid to prepare a CHA zeolite, and supporting a transition metal and a rare earth metal that is different from the transition metal on the prepared CHA zeolite.

Abstract: In an air conditioner, a drain extraction unit and a refrigerant pipe connecting unit may be disposed in a blocking region in which a discharge port is not provided so that a size of the discharge port may be secured and the discharge port may be uniformly disposed, thereby generating uniform airflow in a room. In a lower housing formed in a circular shape, some of components inside an indoor unit of the air conditioner may be disposed in a protrusion portion that protrudes from the circular housing, thereby facilitating the installation of the air conditioner. A condensate water collecting space disposed outside the housing may be provided in a drain tray, thereby efficiently preventing a leakage due to condensate water generated outside the housing. The housing, the drain tray, and the cover member of the air conditioner may be coupled by a coupling member coupled outside.

Abstract: Disclosed herein is an air conditioner including a suction panel which includes a suction port through which air is suctioned in inside a housing. The suction panel is formed to rotate with an axial direction of an air blowing fan or a direction perpendicular to the axial direction of the air blowing fan as a rotation axis to be coupled with or separated from the housing. Accordingly, a user may easily and intuitively separate the suction panel and falling of the suction panel, which may occur when the suction panel is separated, may be effectively reduced using a supporting unit disposed at the suction panel. Also, the housing and cover members which cover an outer perimeter of a lower portion of the housing may be coupled with each other by pressurizing the cover members toward the housing, thereby allowing the user to easily coupled the cover members.

Abstract: Provided is a method for producing zeolite having a controlled aluminum content, wherein the sodium hydroxide molar concentration of a zeolite synthesis mixture can be adjusted to adjust the aluminum content in synthesized CHA. The structure of the low aluminum-content CHA produced by the provided method does not collapse even after high-temperature hydrothermal treatment, and thus the catalytic activity of the CHA can be maintained. Moreover, by adjusting the aluminum content in the framework, the properties of the produced CHA significantly change, and thus the CHA can be applied to various fields.
