Patent

CA 2499858

Used titanium-containing silicon oxide catalysts are regenerated by heating the used catalyst at a temperature of at least 400 ~C in the presence of a oxygen-containing gas stream, followed by impregnation with a titanium source, and then calcining the impregnated catalyst to form a reactivated catalyst.

Des catalyseurs usagés d'oxyde de silicium contenant du titane sont régénérés par le réchauffement du catalyseur usagé à une température égale ou supérieure à 400 ·C en présence d'un flux gazeux oxygéné, suivi d'une imprégnation avec une source de titane, et ensuite une calcination du catalyseur imprégné pour former un catalyseur réactivé.
