Catalyst, catalyst precursor, method of producing catalyst, catalyst packed reaction tube, and method of decomposing nitrous oxide

Abstract

A catalyst capable of efficiently decomposing nitrous oxide, a precursor thereof, a method of producing the catalyst, a method of decomposing nitrous oxide and a catalyst packed reaction tube capable of efficiently decomposing nitrous oxide are described. The catalyst includes a titanium oxide-containing carrier carrying a component containing ruthenium and/or ruthenium compound(s). The catalyst forms a catalyst packed bed in a reaction tube, in which the catalyst has a honeycomb structure such that a packing volume ratio is from 35 to 50 vol % when the catalyst packed bed is formed. A method of decomposing nitrous oxide includes a step of bringing the catalyst into contact with a nitrous oxide-containing gas.
