Abstract: The present invention provides an apparatus for generating carbon dioxide and a greenhouse using the same. The apparatus for generating carbon dioxide in the present invention which reduces harmful exhaust gas as a post-treatment system having a metal particulate filter (MPF) catalyst and reuses stored energy for heating as a heat storage system storing exhaust heat in a heat storage tank, and also adsorbs CO or HC, a harmful component emitted in initial operation of the apparatus for generating carbon dioxide, then reuses the adsorbed CO or HC, thereby contributing to the effective use of the energy as well as reducing the harmful exhaust gas. In case of applying the apparatus for generating carbon dioxide to the greenhouse, the moisture, which is emitted when operating the apparatus for generating carbon dioxide, is emitted with the harmful exhaust gas, thereby maintaining a constant humidity in the greenhouse.

Abstract: PURPOSE: An apparatus for reducing nitrogen oxides and preventing knocking of a car using dimethyl ether as a fuel, and a dimethyl ether car equipped with the same are provided to use a reducing agent which is generated by a dimethyl ether-steam reformed catalytic reaction as the reducing agent of a lean NOx trap catalyst, thereby reducing the nitrogen oxides and improving engine performance. CONSTITUTION: An apparatus(100) for reducing nitrogen oxides and preventing knocking comprises a first catalyst part(110), a second catalyst part(120), and a temperature sensor. The first catalyst part includes an SR(Steam Reforming) catalyst which reacts with DME(dimethyl ether) in order to generate a reducing agent. The second catalyst part at the rear end of the first catalyst part includes an LNT(lean NOx trap) catalyst which reacts with the reducing agent supplied from the first catalyst part. The temperature sensor detects the temperature of the second catalyst part. When the temperature of the second catalyst part detected by the temperature sensor is more than 350°C, the reducing agent is supplied to the engine of a DME car. The reducing agent is at least one of H2 and CO. Exhaust gas discharged from the engine part of the DME car and the DME injected from an injector are supplied to the first catalyst part. [Reference numerals] (AA) Combustion temperature 800-1000°C; (BB) Exhaust gas(temperature 800-50°C); (CC) Exhaust temperature 50-80°C
