In the early days of EO production, the typical start-of-cycle selectivity for EO catalysts ranged from 68 to 70%, i.e., 30% or more of the ethylene feed to the process was lost to the complete combustion side reaction. •[ª˜ˆ{é;¦•×hÑÑáÙñ�)•h NÒ72éS(2ğÍß—¡×:Hıd1ªãFĞ…“&i�)Ùyùk€8Ñ’ /¡š—ÒOí1•º¯ş‰u&7�¾�.
