The present invention relates to a process for producing trifluoroethylene in a reactor provided with a fixed catalytic bed comprising a catalyst, said process comprising the steps of: a) reacting chlorotrifluoroethylene with hydrogen in the presence of the catalyst and in the gas phase to produce a stream A comprising trifluoroethylene; b) treating said stream A under conditions sufficient to produce a stream D1 comprising 1,1,2-trifluoroethane in a content of less than 15% by weight on the basis of the total weight of said stream D1, c) recycling stream D1 to step a).
