Title:

触媒再生方法

Document Type and Number:

Japanese Patent JP4970240

Kind Code:

B2

Abstract:

Used noble metal-containing titanium zeolite catalysts, that have been employed in the liquid-phase epoxidation of olefins with hydrogen and oxygen in the presence of a buffer, are regenerated by heating the used catalyst at a temperature of at least 250° C. in the presence of a oxygen-containing gas stream, followed by reduction at a temperature of at least 20° C. in the presence of a hydrogen-containing gas stream to form a reactivated catalyst.
