摘要: 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.

摘要: An exhaust gas purification device suppresses a pressure loss increase and includes a honeycomb substrate and inflow cell side catalyst layer. The substrate includes a porous partition wall defining several cells extending from an inflow side end surface to an outflow side end surface. The cells include an inflow and outflow cell adjacent across the wall. The inflow cell has an open inflow side end and sealed outflow side end. The outflow cell has a sealed inflow side end and open outflow side end. The catalyst layer is on an inflow cell side surface in an region extending from the inflow side end positioned 10% or more of the partition wall length. At this position, a filled portion of the inflow cell side catalyst layer pores are 40% or less. The pores are present to a depth of 50% of a thickness of the partition wall.
