Definitions

  • the present invention relates to a catalytic process for the synthesis of trifluoroethylene.
  • the invention relates to a process for the synthesis of trifluoroethylene by reaction of chlorotrifluoroethylene with hydrogen in the presence of a heterogeneous catalyst.
  • U.S. Pat. No. 3,564,064 16.02.1971 discloses the catalytic gas-phase reaction of chlorotrifluoroethylene with hydrogen to produce trifluoroethylene in the presence of a catalyst comprising palladium or platinum supported on activated carbon. This process may proceed with high conversion of chlorotrifluoroethylene but with a parallel reduction in the yield of trifluoroethylene.
  • a first object of the present invention is a process for preparing trifluoroethylene comprising contacting chlorotrifluoroethylene with hydrogen in the presence of a catalyst consisting of palladium or platinum supported on activated carbon, in which the activated carbon is extruded activated carbon.
  • a second object is a catalyst for the hydrodechlorination of chlorotrifluoroethylene, said catalyst consisting of palladium or platinum supported on activated carbon, characterized in that the activated carbon is extruded activated carbon.
  • activated carbon is generally used to collectively refer to processed carbonaceous materials characterized by a porous structure and a large internal surface area, generally comprised between 500 and 1500 m 2 /g.
  • Activated carbon is obtained on a commercial scale from carbon containing raw materials, e.g. wood, peat, coconut shells, by chemical or gas activation.
  • Activated carbon is commercially available in different forms, namely granular, powdered or extruded form.
  • Extruded activated carbon is typically obtained from finely powdered raw materials by mixing with a suitable binder followed by extrusion, to form pellets or strands which are then cut into pieces. The pellets are then chemically activated or carbonized and finally gas activated. Typical extruded activated carbons have a pellet diameter in the range of 0.8 to 130 mm.
  • Suitable extruded activated carbons for the process of the invention are available commercially for instance from Norit Nederland B.V., Degussa AG, Calgon Carbon Corporation.
  • the process of the invention is preferably carried out in the gas-phase.
  • a gaseous stream of hydrogen and chlorotrifluoroethylene is fed to the reaction zone and brought into contact with the catalyst held at a suitable temperature.
  • the produced trifluoroethylene is recovered from the effluent gas.
  • the reaction products and any unreacted starting material may be recovered and isolated by conventional methods.
  • the main by-product of the process has been identified to be CH 2 FCHF 2 .
  • the molar ratio between the hydrogen and the chlorotrifluoroethylene fed to the reaction zone is typically comprised between 0.75:1 and 1.25:1, preferably between 0.9:1 and 1.1:1.
  • An inert gas may be optionally mixed with hydrogen and chlorotrifluoroethylene.
  • Suitable inert gases are for instance nitrogen, helium, argon.
  • the inert gas is nitrogen.
  • the inert gas may serve as a diluent to reduce the concentration of the reactants and/or the products below the point where they form flammable mixtures.
  • the concentration of chlorotrifluoroethylene in the gaseous stream fed to the reaction zone is conveniently comprised between 5 and 55% by volume, preferably between 10 and 50% by volume.
  • the reaction pressure is not critical to the process. Generally the process is carried out at pressure of from 0.01 MPa to 0.5 MPa, preferably at a pressure of from about 0.05 MPa to 0.2 MPa.
  • the reaction may be conducted at any suitable temperature, generally at a temperature in the range of from 100° C. to 350° C., preferably in the range of from 150° C. to 300° C., and more preferably in the range of from 200° C. to 250° C.
  • the reaction contact time for the reactants may be any suitable contact time, usually a time of from 0.1 second to 100 seconds, preferably from 0.1 second to 60 seconds, and more preferably from 0.5 second to 30 seconds.
  • any suitable space velocity of the reactants may be employed.
  • the space velocity can be in the range from 0.2 to 50 gCTFE*h ⁇ 1 *g cat ⁇ 1 , preferably from 1 to 40 gCTFE*h ⁇ 1 *g cat ⁇ 1 and more preferably from 2 to 30 gCTFE*h ⁇ 1 *g cat ⁇ 1 .
  • the process may be conducted in any suitable reaction vessel.
  • the reaction vessel should be constructed of materials which are inert towards the reactants as well as the products, such as for example, Hastelloy, Inconel, Monel, stainless steel vessels.
  • the process is carried out in a tubular stainless steel reactor, provided with suitable means to maintain the required temperature inside the reactor.
  • the catalyst used in the process consists of platinum or palladium supported on extruded activated carbon.
  • the catalyst consists of palladium supported on extruded activated carbon.
  • the amount of metal supported on the extruded activated carbon is typically comprised between 0.05 and 5% by weight, preferably between 0.1 and 4% by weight, more preferably between 0.2 and 3% by weight, and even more preferably between 0.3 and 2.5% by weight.
  • the catalyst may be prepared by conventional methods, such as the incipient wetness impregnation method. In such a method an aqueous solution of a suitable metal precursor is added to the support, dried, followed by reduction of the metal.
  • a suitable metal precursor mention can be made of PdCl 2 , Pd(NO 3 ) 2 , H 2 PtCl 4 .
  • NORIT® RX3 EXTRA (Norit Nederland B.V.) extruded activated carbon having BET area of 1400 m 2 /g
  • NORIT® GCN 1240 (Norit Nederland B.V.) granular activated carbon having BET area of 1300 m 2 /g
  • the activated carbon as received from the supplier was crushed and sieved in order to obtain granules with a diameter of 0.5-1 mm.
  • the granules were dried under vacuum at 200° C. and then impregnated with incipient wetness method with an aqueous hydrochloridric solution of PdCl 2 to obtain different concentrations of palladium on the support.
  • Catalyst activation Each catalyst was dried under a nitrogen flow at 300° C. for 6 h and then reduced in a H 2 /N 2 stream (5% by volume H 2 ) from room temperature to 350° C. with thermal ramp of 5° C./min. After 30 minutes at 350° C. hydrogen concentration was raised to 10% by volume and kept for 30 minutes, followed by a treatment with a hydrogen concentration of 50% by volume for 4 h. At the end of the treatment the catalyst was cooled at room temperature and characterized to determine the effective concentration of palladium.
  • Catalyst C Following the general catalyst preparation procedure described above one catalyst was prepared using the granular activated carbon NORIT® GCN 1240 as the support and having a palladium concentration of 1.17% by weight (Catalyst C).
