Catalyst module for removing harmful gas and manufacturing method therefor, catalyst system comprising same for removing harmful gas, harmful substance removing apparatus comprising catalyst module for removing residual ozone and manufacturing method therefor, and harmful substance removing system comprising same

A catalyst module for removing harmful gas, comprising:

• a heating carrier comprising an electrically heatable heating body, the heating carrier including one or more flow channels inside, and having a porous structure with pores;
• and
• a catalyst region formed on at least a portion of the surface of the heating carrier including the flow channels and containing a catalyst material for promoting a decomposition reaction of harmful gas passing through the flow channels,
• wherein the heating carrier includes a plurality of flow channels extending from one end to an opposite end thereof,
• wherein the one end of the flow channel is an inlet through which a fluid is introduced and the opposite end is an outlet through which the fluid is discharged,
• wherein the heating carrier has the resistance in the range of 0.5Ω to 500Ω, has a porosity in a range of 20% by volume to 70% by volume, and comprises SiC-based compound,
• wherein the catalyst region comprises:
• a first catalyst layer having a first catalyst material loading amount, the first catalyst layer formed in the pores of the heating carrier;
• and
• a second catalyst layer applied on an inner surface of the first catalyst layer formed in the pores of the heating carrier, second catalyst layer having a second catalyst material loading amount higher than the first catalyst material loading amount.
