Abstract

A catalytic process for the synthesis of trifluoroethylene from chlorotrifluoroethylene which comprises contacting chlorotrifluoroethylene with hydrogen in the presence of a catalyst consisting of palladium or platinum supported on extruded activated carbon.

Claims

exact text as granted — not AI-modified
1 - 4 . (canceled) 
     
     
         5 . A catalyst consisting of palladium or platinum, supported on activated carbon, wherein the activated carbon is extruded activated carbon. 
     
     
         6 . The catalyst according to  claim 5 , wherein the amount of said palladium or said platinum supported on the extruded activated carbon is between 0.05 and 5% by weight. 
     
     
         7 . The catalyst according to  claim 6 , wherein the amount of said palladium or said platinum supported on the extruded activated carbon is between 0.1 and 4% by weight. 
     
     
         8 . The catalyst according to  claim 7 , wherein the amount of said palladium or said platinum supported on the extruded activated carbon is between 0.2 and 3% by weight 
     
     
         9 . The catalyst according to  claim 8 , wherein the amount of said palladium or said platinum supported on the extruded activated carbon is between 0.3 and 2.5% by weight. 
     
     
         10 . The catalyst according to  claim 5 , wherein the extruded activated carbon has a surface area of between 500 and 1500 m 2 /g. 
     
     
         11 . The catalyst according to  claim 5 , wherein the extruded activated carbon is in the form of pellets having a pellet diameter between 0.8 and 130 mm. 
     
     
         12 . The catalyst according to  claim 5 , consisting of the palladium supported on the extruded activated carbon. 
     
     
         13 . The catalyst according to  claim 6 , consisting of the palladium supported on the extruded activated carbon. 
     
     
         14 . The catalyst according to  claim 7 , consisting of the palladium supported on the extruded activated carbon. 
     
     
         15 . The catalyst according to  claim 8 , consisting of the palladium supported on the extruded activated carbon. 
     
     
         16 . The catalyst according to  claim 9 , consisting of the palladium supported on the extruded activated carbon.
