Nitrous oxide decomposition method and nitrous oxide decomposition device

Abstract

Provided are a nitrous oxide decomposition method and a decomposition apparatus capable of efficiently decomposing nitrous oxide in a nitrous oxide-containing gas. Disclosed are: a method of decomposing nitrous oxide, which includes the step of bringing a catalyst including a titanium oxide-containing carrier carrying a component containing at least one kind selected from the group consisting of ruthenium and ruthenium compounds into contact with a nitrous oxide-containing gas containing nitrous oxide, water vapor and ammonia; and a nitrous oxide decomposition apparatus including a reactor filled with the above catalyst and a line that is connected to the reactor and supplies the nitrous oxide-containing gas to the reactor.

Dependencies are inferred from the claim text.
