Title
(EN) CATALYST FOR THE OXIDATIVE DEHYDROGENATION OF HYDROCARBONS AND PREPARATION THEREOF
(FR) CATALYSEURS POUR LA DESHYDROGENATION OXYDATIVE DES HYDROCARBURES
Abstract
(EN)
The present invention provides a catalyst for the oxidative dehydrogenation of a lower hydrocarbon to form at least one higher hydrocarbon and/or lower olefin. In one embodiment, the catalyst includes a nonstoichiometric rare earth oxycarbonate of the formula MxCyOz having a disordered and/or defect structure, wherein M is at elast one rare earth element selected from the group consisting of La, Pr, Nd, Sm, Eu, Gd, Tb, Dy, Ho, Er, and Tm; X = 2; Z = 3 + AY; A is less than about 1.8, and Y is the number of carbom atoms in the oxycarbonate. When used for the oxidative dehydrogenation of a lower hydrocarbon at a pressure above bout 100 psig. the catalyst has a selectivity of at least about 40 percent to at least one higher hydrocarbon and/or lower olefin. Methods for preparing catalysts taught by the invention and processes for using the catalysts for the oxidative dehydrogenation of lower hydrocarbons are also provided.

L'invention concerne un catalyseur conçu pour la déshydrogénation oxydative d'un hydrocarbure inférieur pour former au moins un hydrocarbure supérieur et/ou une oléfine inférieure. Dans un mode de réalisation, le catalyseur comporte un oxycarbonate des terres rares non stoechiométrique de la formule MXCYOZ présentant une structure désordonnée et/ou défectueuse, dans laquelle M représente au moins un élément des terres rares choisi dans le groupe composé de La, Pr, Nd, Sm, Eu, Gd, Tb, Dy, Ho, Er et Tm; X = 2; Z = 3 + AY, A étant inférieur à environ 1,8 et Y représentant le nombre d'atomes de carbone dans l'oxycarbonate. Utilisé pour la déshydrogénation oxydative d'un hydrocarbure inférieur à une pression supérieure à environ 100 psig, le catalyseur présente une sélectivité d'au moins environ 40 % à au moins un hydrocarbure supérieur et/ou une oléfine inférieure. L'invention concerne également des procédés de préparation de tels catalyseurs ainsi que leurs techniques d'utilisation pour la déshydrogénation oxydative d'hydrocarbures inférieurs.
