OXIDATIVE COUPLING OF METHANE OVER MODIFIED ALKALINE EARTH OXIDES

摘要

Methane conversions at lower temperature were studied. The aetivity of Y₂O₃ sample at 823K was fairly high with some formation of C₂H₄ and C₂H₆, the catalysts based on alkaline earth oxides and yttria would give better results. The influences of flux ratio, space velocity, and reaction temperature were also discussed.
