Ethylene oxide prepn. by reacting ethylene and oxygen - using silver catalyst on alkali soluble silicon cpd.-deficient alpha-alumina support

摘要

Alpha-Al2O3-supported Ag catalysts for ethylene oxide prepn., from C2H4 and O2, contain less than 0.001 wt.% alkali-soluble Si cpds. (I), calculated as SiO2 and w.r.t. total catalyst wt. Long catalyst life can be achieved without loss in activity and selectivity.
