Patent

CA 2002650

In a process for dehydrogenating alkanes containing 2-5 carbon atoms per molecule in the presence of steam and a catalyst composition comprising IIA and/or IIB metal aluminate, a noble metal and a Group IVA metal oxide, the improvement comprises the step of contacting the catalyst composition, after it has been oxidatively regenerated, with a reducing gas comprising free hydrogen and steam.

Dans un procédé pour la déshydrogénation des alcanes contenant 2 à 5 atomes de carbone par molécule en présence de vapeur et d'une composition de catalyseur comprenant un aluminate d'un métal du groupe IIA et/ou IIB, un métal noble et un oxyde de métal du groupe IVA, l'amélioration comprend l'étape de mise en contact de la composition de catalyseur, qui est ensuite régénérée par oxydation, à l'aide d'un gaz réducteur comprenant de l'hydrogène libre et de la vapeur.
