Abstract
Procédé de transformation de méthane en éthylène et/ou en éthane par dimérisation par oxydation. Il consiste à mettre en contact à plusieurs reprises successives d'une part un mélange gazeux de méthane et d'oxygène, et d'autre part un catalyseur approprié et une matière poreuse adsorbante ou absorbante susceptible de piéger l'éthane et l'éthylène par adsorption ou absorption, et à effectuer une adjonction intermédiaire d'oxygène par l'intermédiaire d'un conduit traversant d'alimentation en gaz, ou par voie électrochimique à l'aide d'un électrolyte solide. Le procédé peut être mis en oeuvre aussi bien dans un appareil à recyclage de gaz que dans un appareil à débit continu. Dans le cas d'un appareil à débit continu, on peut recycler partiellement le gaz et également recycler en continu le catalyseur solide ou la matière adsorbante ou absorbante solide. On libère par chauffage l'éthane et l'éthylène piégés dans la matière poreuse adsorbante ou absorbante à une température inférieure à celle du catalyseur, et on met en contact avec le mélange gazeux un second piège ou produit solide recyclé de piégeage, puis on répète le processus en continu. Ce nouveau procédé a déjà permis d'obtenir en laboratoire un rendement en éthylène supérieur à 75 % et des rendements globaux en éthane et en éthylène (C¿2?) supérieurs à 80 %.
