RECOVERY OF RHENIUM FROM A RHENIUM-CONTAINING TITANIA CATALYST

A method is provided for recovering rhenium from a titania- supported, rhenium-containing catalyst by treating the catalyst in the reduced form with an acid in an amount and for a time sufficient to dissolve the rhenium without dissolving the support. L'invention concerne un procédé de récupéra...

Zusammenfassung:	A method is provided for recovering rhenium from a titania- supported, rhenium-containing catalyst by treating the catalyst in the reduced form with an acid in an amount and for a time sufficient to dissolve the rhenium without dissolving the support. L'invention concerne un procédé de récupération du rhénium à partir d'un catalyseur contenant du rhénium et supporté sur du dioxyde de titane. Le procédé consiste à traiter le catalyseur sous une forme réduite avec un acide en une quantité et pour une durée suffisantes pour dissoudre le rhénium sans dissoudre le support.
