Abstract:
1. An ozone processing apparatus that processes a process object by using ozone gas, comprising: a processing part having a processing space configured to contain a process object therein; an ozone generator configured to generate ozone gas from an oxygen-containing gas through an electric discharge; an ozone supply line provided to supply the ozone gas generated by the ozone generator into the processing space of the processing part; a steam generator configured to generate water vapor; a steam supply line connected to the ozone supply line to supply the water vapor generated by the steam generator into the ozone supply line; a metal trap arranged in the ozone supply line at a portion thereof downstream of a joint between the ozone supply line and the steam supply line such that a mixed fluid containing the ozone gas and the water vapor is introduced into the metal trap, the metal trap containing an adsorbent composed of a silicon-containing material; a cooler arranged in the ozone supply line at a portion thereof downstream of the metal trap to cool the mixed fluid containing the ozone gas and the water vapor having been passed through the metal trap; and a gas-liquid separator arranged in the ozone supply line at a portion thereof downstream of the cooler to separate the ozone gas contained in the mixed fluid cooled by the cooler from condensed water generated by cooling the water vapor.
