The present invention relates to an exhaust gas purification apparatus and an exhaust gas purification method using the same. According to a specific embodiment, the exhaust gas purification apparatus comprises: a diesel oxidation catalyst (DOC) unit for converting nitrogen oxides (NO), contained in an exhaust gas introduced therein through a gas inlet portion, into nitrogen dioxide (NO); a composite diesel particulate filter (DPF) unit connected to the rear end of the DOC unit through an inflow line and removing harmful components including particulate substances and nitrogen oxides from the exhaust gas discharged from the DOC unit and introduced therein; and a circulation line disposed in the inflow line so as to introduce the exhaust gas discharged from the DOC unit into the gas inlet portion.

Provided are a novel transition metal complex where a monocyclopentadienyl ligand to which an amido group is introduced is coordinated, a catalyst composition including the same, and an olefin polymer using the catalyst composition. The transition metal complex has a pentagon ring structure having an amido group connected by a phenylene bridge in which a stable bond is formed in the vicinity of a metal site, and thus, a sterically hindered monomer can easily approach the transition metal complex. By using a catalyst composition including the transition metal complex, a linear low density polyolefin copolymer having a high molecular weight and a very low density polyolefin copolymer having a density of 0.910 g/cc or less can be produced in a polymerization of monomers having large steric hindrance. Further, the reactivity for the olefin monomer having large steric hindrance is excellent.
