The invention relates to a method and to an apparatus for separating and utilizing carbon dioxide. According to the invention, carbon dioxide (3a, 3b) is separated from air (1a) being conducted to a building and/or from air (1c,1d) being circulated in the building to reduce the level of carbon dioxide in indoor air (1b) of the building (4), the carbon dioxide (3a, 3b) is recovered, and the carbon dioxide is conducted to a carbon dioxide treatment stage (5), where a chemical compound (6) is formed from the carbon dioxide. In addition, the invention relates to the use of the method.

The invention relates to a catalyst comprising a mixture of AFX-structure and BEA-structure zeolites and at least one additional transition metal, to the process for preparing same and to the use thereof for the selective catalytic reduction of NOx in the presence of a reducing agent such as NH.sub.3 or H.sub.2.

The invention provides a device and system for decomposing and oxidizing of gaseous pollutants. A novel reaction portion reduces particle formation in fluids during treatment, thereby improving the defect of particle accumulation in a reaction portion. Also, the system includes the device, wherein a modular design enables the system to have the advantage of easy repair and maintenance.

A system and method of abating air pollution and stimulating crop growth. A reagent is introduced to a crop canopy to neutralize air pollutants within said canopy, wherein the reagent induces an oxidation-reduction chemical reaction with the air pollution present throughout the acreage of crops, and by means of the reaction effectually neutralizes the harmful effects of the air pollutants on the crops. The reagent is diluted using a venturi valve or other means. The flow rate of said reagent is regulated using an electronic control unit, based on data collected from at least one type of sensor in the canopy that is in communication with the control unit.
