Patent

CA 2456530

A catalyst suitable for the dehydrogenation and hydrogenation of hydrocarbons comprises at least one first metal and at least one second metal bound to a support material. The at least one first metal comprises at least one transition metal, suitably a platinum group metal. The support material is provided with an overlayer such that acidic sites on the support material are substantially blocked. In a preferred embodiment the catalyst is also substantially chloride free. Method of preparing catalyst are also disclosed.

L'invention concerne un catalyseur adapté à la déshydrogénation et la hydrogénation d'hydrocarbures, comprenant au moins un premier métal et au moins un second métal fixé sur un matériau de support. Ledit premier métal comprend au moins un métal de transition, de préférence, un métal du groupe platine. Le matériau de support est pourvu d'une surcouche, de telle sorte que des sites acides sur le matériau de support soient sensiblement bloqués. Dans un mode de réalisation privilégié, le catalyseur est également essentiellement exempt de chlorure. L'invention concerne également des procédés permettant de préparer des catalyseurs.
