The methane partial oxidation method of using the fine oxygen selective transmission ceramic membrane

摘要

Regarding to the high-level part of the flow of the gas which contains the methane of the oxygen transmitted type membrane type reactor, and, regarding to the downstream part of the flow of the gas which contains the methane of the same reactor by doing level arrangement the methane partial oxidation catalyst of precious metal base, in the ceramic membrane surface vicinity where such as Ni system oxygen exudes or Ru whose carbon precipitation characteristic of the quantity where oxidation deactivation does not occur is low, arranging the methane partial oxidation catalyst whose carbon precipitation characteristic is low vis-a-vis the ceramic membrane threely-dimensional, furthermore, to the same reactor the feed the carbon in the same gas to the gas which contains the methane which is doneVis-a-vis the quantity from 0.25 at 0.5 ratios throwing vapor, the methane partial oxidation method of featuring.
