Abstract: A system to abate an emission stream from a semiconductor manufacturing process is disclosed. The system includes a plurality of sections configured to pass an emission stream therethrough. The sections include a metal oxide media section to remove a hydride from the emission stream; a desiccate media section downstream to the metal oxide media section to remove moisture from the emission stream; and a catalytic media section downstream to the desiccate media section to remove a nitrogen oxide (NOx) from the emission stream. The abatement system provides carbon-free abatement of nitrogen oxide and hydride(s). The abatement system has significantly lower cost to manufacture and operate.

Abstract: The present disclosure provides an exhaust gas purification catalyst with increased exhaust gas purification performance. The exhaust gas purification catalyst has a porous support, catalyst metal particles supported in the pores of the porous support, and zirconium dioxide particles supported in the pores of the porous support. The zirconium dioxide particles are supported in a uniformly dispersed manner in the pores, as monoclinic crystals or a mixture of monoclinic crystals and tetragonal crystals, the phrase “supported in a uniformly dispersed manner” meaning that when the exhaust gas purification catalyst is measured with an electron beam microanalyzer, the proportion of the abundance ratio of zirconium in a surface region up to a depth of 1.5 μm from the exhaust gas purification catalyst surface with respect to the abundance ratio of zirconium in the region inward from that surface region of the exhaust gas purification catalyst, is 95 to 105 mol %.
