Abstract

Official abstract text for this publication.

A partial oxidative coupling catalyst has a structure in which a component represented by M 2 ZrO 3 is supported on a support, where M represents an alkali metal.

First claim

Opening claim text (preview).

The invention claimed is: 1 . An olefin production device for producing an olefin from a raw material gas containing methane, comprising: at least one reactor containing a partial oxidative coupling catalyst, and a plurality of the reactors connected in series, wherein the partial oxidative coupling catalyst comprises a support and a component represented by M 2 ZrO 3 supported on the support, where M represents an alkali metal. 2 . The olefin production device according to claim 1 , further comprising a cooler disposed between adjacent reactors. 3 . An olefin production method for producing an olefin from a raw material gas containing methane, comprising: a first reaction step of performing partial oxidative coupling of methane in the raw material gas by using a partial oxidative coupling catalyst, wherein the partial oxidative coupling catalyst comprises a support and a component represented by M 2 ZrO 3 supported on the support, where M represents an alkali metal. 4 . The olefin production method according to claim 3 , comprising a second reaction step of performing partial oxidative coupling of methane in an effluent gas of the first reaction step by using the partial oxidative coupling catalyst. 5 . The olefin production method according to claim 4 , further comprising a step of cooling the effluent gas between the first reaction step and the second reaction step. 6 . The olefin production method according to claim 4 , wherein each of a flow velocity of a reactant gas obtained by mixing the raw material gas and oxygen in the first reaction step and a flow velocity of a reactant gas obtained by mixing the effluent gas and oxygen in the second reaction step is 10 to 100 cm/sec.
