An apparatus for decomposing perfluorinated compounds, the apparatus comprising:
- a first processing device configured to pre-process a gas to be processed;
- a reactor including a heating portion and a catalyst portion, wherein the heating portion is configured to apply heat to the gas, and the catalyst portion includes a catalyst for decomposing perfluorinated compounds, wherein the reactor is configured to decompose a perfluorinated compound included in the gas, after the gas passes through the first processing device;
- and
- a second processing device configured to post-process the gas after the gas passes through the reactor,
- wherein the catalyst portion includes:
- an alumina carrier;
- at least one metal carried on the alumina carrier and selected from the group consisting of Zn, Ni, W, Zr, Ti, Ga, Nb, Co, Mo, V, Cr, Mn, Fe, and Cu;
- S carried on the alumina carrier;
- and
- rare-earth metals carried on the alumina carrier,
- wherein a mole ratio of the alumina carrier, the at least one metal, S, and the rare-earth metals of the catalyst portion is expressed as follows:
- 100:x:y:z,
- wherein x represents a quantity of the at least one metal, y represents a quantity of S, and z represents a quantity of the rare-earth metals, and
- wherein x is 10 to 20, y is 2.5 to 5, and z is 0.1 to 0.5.
