PROCESS FOR PREPARING A CATALYST, CATALYST AND PROCESS FOR THE OXIDATIVE DEHYDROGENATION OF HYDROCARBONS

摘要

A process for preparing a catalyst provided in the form of a metal oxide catalyst having at least one element selected from Mo, Te, Nb, V, Cr, Dy, Ga, Sb, Ni, Co, Pt and Ce. The catalyst is subjected to an aftertreatment to increase the proportion of the M1 phase, by contacting the catalyst with steam at a pressure below 100 bar or by contacting the catalyst with oxygen to obtain an aftertreated catalyst. The aftertreated catalyst may be used for oxidative dehydrogenation processes.

1. A process for preparing a catalyst, wherein a catalyst is provided in the form of a metal oxide catalyst which comprises at least one element of the group Mo, Te, Nb, V, Cr, Dy, Ga, Sb, Ni, Co, Pt and Ce,
characterized in that the catalyst is subjected to an aftertreatment to increase the fraction of the M1 phase of the catalyst, wherein the catalyst, with generation of an aftertreated catalyst,
is contacted with steam at a pressure below 100 bar, preferably below 80 bar, preferably below 50 bar, and/oris contacted with oxygen.
