PROCESS FOR PRODUCING PROPYLENE OXIDE

摘要

A PROCESS FOR PRODUCING PROPYLENE OXIDE COMPRISING REACTING PROPENE WITH HYDROGEN (H) PEROXIDE IN THE PRESENCE OF A CATALYST TO GIVE A MIXTURE (GI) COMPRISING PROPYLENE OXIDE, UNREACTED PROPENE, AND OXYGEN; SEPARATING PROPYLENE OXIDE FROM MIXTURE (GI) TO GIVE A MIXTURE (GII) COMPRISING PROPENE AND OXYGEN; AND ADDING HYDROGEN (H) TO MIXTURE (GII) AND REDUCING THE OXYGEN COMPRISED IN MIXTURE (GII) AT LEAST PARTIALLY BY REACTION WITH HYDROGEN (H) IN THE PRESENCE OF A CATALYST COMPRISING COPPER IN ELEMENTAL AND/OR OXIDIC FORM ON A SUPPORT, WHEREIN COPPER IS PRESENT ON THE SUPPORT IN AN AMOUNT OF 30 TO 80 WT-% BASED ON THE WHOLE CATALYST AND CALCULATED AS CUO.
