摘要： An object of the present invention is to provide a heating carrier that does not heat all of exhaust gas flowing into a catalyst converter, but directly supplies, to a catalyst layer, thermal energy in the form of an instantaneous pulse to effectively activate a catalyst during a cold start-up period, and thus may reduce emission pollutants with a small amount of energy, and an exhaust gas reduction carrier having the heating carrier. In order to accomplish the object, the heating carrier of the present invention may include a main body of which the inside is formed to have a honeycomb structure, the main body being formed of a conductive ceramic material that is a nonmetallic heating element; and a catalyst layer formed by coating a first catalyst on a surface of the main body.

摘要： Proposed is a carbon dioxide reforming (CDR) reactor having a multilayered catalyst layer arrangement for preventing catalyst deactivation, wherein, in the reactor in which a CDR reaction for reacting methane (CH4) with carbon dioxide (CO2) to reform the methane into a synthesis gas including carbon monoxide (CO) and hydrogen (H2) is performed, in order to prevent a case where an endothermic reaction between a catalyst and heated reactant gas supplied to the reactor gradually causes the temperature of the reactant gas to decrease and the catalyst is deactivated by cokes generated due to the decrease in temperature of the reactant gas, CDR catalysts in the reactor are arranged in multiple layers in a multilayered structure to allow the reactant gas temperature that has decreased due to the endothermic reaction to be restored in spaces between the catalyst layers.

摘要： The present invention relates to a low-concentration air pollutant selective detection device and, more specifically, to a low-concentration air pollutant selective detection device capable of detecting a low-concentration air pollutant with high sensitivity, and selectively detecting an air pollutant when necessary. The low-concentration air pollutant selective detection device of the present invention comprises: a sensor which is located in a flow path, through which the gas moves, to detect contaminants in the gas; and a concentrator part which, by including an adsorbent that is positioned in the flow path of the gas that moves to the sensor and adsorbs contaminants in the gas, and a desorption means that is positioned adjacent to the adsorbent to individually desorb different contaminants from the adsorbent, delivers the concentrated contaminants to the sensor.

摘要： An object of the present invention is to increase the reduction performance of nitrogen oxides compared to existing three-way catalysts; simultaneously inhibit the emission of ammonia and nitrous oxide; simplify a process by means of a method of further doping an iridium-ruthenium catalyst into a commercial three-way catalyst; and expand the scope of application. The present invention provides a catalyst for simultaneously inhibiting the emission of ammonia and nitrous oxide by doping an iridium-ruthenium catalyst component into a three-way catalyst (TWC), a diesel oxidation catalyst, or a lean NOx trap supported on a honeycomb support.
