摘要： The invention concerns a process for oxidative dehydrogenation of ethane. In the process an ethane comprising stream is fed to a distillation column to remove propane. The purified ethane stream is subjected to oxidative dehydrogenation using a catalyst comprising Mo/V/Sb, or Mo/V/Nb and Te or Sb in the orthorhombic M1 crystalline phase. The reactor effluent comprises ethylene. The effluent is washed with water to remove acetic acid. The acetic acid is recovered from the aqueous stream by means of solvent extraction.

摘要： The invention relates to a process for preparing 1,3-butadiene by heterogeneously catalysed oxidative dehydrogenation of n-butene, in which a butene mixture comprising at least 2-butene is provided. The problem that it addresses is that of specifying a process for economically viable preparation of 1,3-butadiene on the industrial scale, which is provided with a butene mixture as raw material, wherein the 1-butene content is comparatively low compared to the 2-butene content thereof, and in which the ratio of 1-butene to 2-butene is subject to variation. This problem is solved by a two-stage process in which, in a first stage, the butene mixture provided is subjected to a heterogeneously catalysed isomerization to obtain an at least partly isomerized butene mixture, and in which the at least partly isomerized butene mixture obtained in the first stage is then subjected, in a second stage, to oxidative dehydrogenation. The two-stage process leads to higher butadiene yields compared to the one-stage process.
