Abstract
The present invention relates to a process for the production of trifluoroethylene in a reactor equipped with a fixed catalytic bed comprising a catalyst, said process comprising a stage a) of reaction of chlorotrifluoroethylene with hydrogen in the presence of the catalyst and in the gas phase in order to produce a stream comprising trifluoroethylene; said stage a) being carried out at a temperature of the fixed catalytic bed T1 of between 50° C. and 250° C.; said process being characterized in that, during stage a), the temperature of the fixed catalytic bed T1 is increased provided that it does not exceed 300° C.

A process for the production of trifluoroethylene in a reactor equipped with a fixed catalytic bed comprising a catalyst, said process comprising a stage a) of reaction of chlorotrifluoroethylene (CTFE) with hydrogen in the presence of the catalyst and in the gas phase in order to produce a stream comprising trifluoroethylene;
- said stage a) being carried out at a temperature of the fixed catalytic bed T1 of between 50° C. and 250° C.;
- wherein, during stage a), the temperature of the fixed catalytic bed T1 is increased provided that it does not exceed 300° C., and
- wherein the flow rate for introduction of the hydrogen or the flow rate for introduction of the CTFE or both into the reactor is reduced in order to increase the temperature of the fixed catalytic bed T1.
A process for the production of trifluoroethylene in a reactor equipped with a fixed catalytic bed comprising a catalyst, said process comprising a stage a) of reaction of chlorotrifluoroethylene with hydrogen in the presence of the catalyst and in the gas phase in order to produce a stream comprising trifluoroethylene;
- said stage a) being carried out at a temperature of the fixed catalytic bed T1 of between 50° C. and 250° C.;
- wherein, during stage a), the temperature of the fixed catalytic bed T1 is increased provided that it does not exceed 300° C., and
- wherein the reactor is equipped with a jacket comprising a heat-transfer fluid in order to control the temperature of the fixed catalytic bed T1 and in that said temperature of the jacket of the reactor T2 is of between 0° C. and 200° C.
