Abstract: 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.

Abstract: The present invention relates to a kit for concentrating low-concentration air pollutants, and to a concentration kit for concentrating low-concentration air pollutants, and then desorbing same so as to detect the components and concentrations of the pollutants. The present invention comprises: a sensor positioned on a channel in which gas moves, so as to detect pollutants in the gas; and a concentration part, which comprises an adsorbent for adsorbing and desorbing the pollutants in the gas moving to the sensor, so as to transfer concentrated pollutants to the sensor.
