Oxidative coupling of methane with membrane reactors containing lead oxide
- The Univ. of Tokyo (Japan). Department of Synthetic Chemistry
Oxidative coupling of methane was conducted by using membrane reactors. The nonporous membrane film that consisted of PbO modified by alkali-metal or alkaline earth compound was supported on a porous tube or nonporous tube of stabilized zirconia. Oxide ion was transported from the oxygen (air) side to the methane side through PbO film. C[sub 2] hydrocarbons were obtained with high selectivity (>90 %), but the activity was influenced by alkali-metal compounds and the supports on which the membrane was formed. The temperature characteristics of the activity indicated that the C[sub 2] formation rate was controlled by O[sup 2[minus]] transportation when the support had low O[sup 2[minus]] conductivity, while it was controlled by both of the catalytic reaction and oxide ion transportation on other supports.
