Abstract

La présente invention concerne un procédé de production du trifluoroéthylène dans un réacteur muni d’un lit catalytique comprenant un catalyseur, ledit procédé comprenant : i) une étape d’activation dudit catalyseur comprenant sa mise en contact avec un flux gazeux comprenant un agent réducteur, un gaz inerte ou mélange de ceux-ci ; et ii) une étape de réaction du chlorotrifluoroéthylène avec de l’hydrogène en présence du catalyseur activé selon l’étape i) et en phase gazeuse pour produire un courant comprenant le trifluoroéthylène ; caractérisé en ce que, au cours de ladite étape i), la température du lit catalytique est augmentée d’une température T1 à une température T2 supérieure à T1 avec un gradient de température inférieure à 0,5°C/min.
