Abstract: 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.

Abstract translation: 本发明提供了用于低级烃的氧化脱氢以形成至少一种较高级烃和/或低级烯烃的催化剂。 在一个实施方案中，催化剂包括具有无序和/或缺陷结构的式MxCyOz的非化学计量稀土氧碳酸盐，其中M为选自La，Pr，Nd，Sm，Eu的弹性一种稀土元素， Gd，Tb，Dy，Ho，Er和Tm; X = 2; Z = 3 + AY; A小于约1.8，Y是碳酸酯中的碳原子数。 当在高于100psig的压力下用于低级烃的氧化脱氢。 催化剂对至少一种较高级烃和/或低级烯烃具有至少约40％的选择性。 还提供了用于制备本发明教导的催化剂的方法和使用该催化剂用于低级烃的氧化脱氢的方法。
