Definitions

  • the present invention concerns improvements in catalytic processes, and improvements in catalysts for such processes. More particularly, it concerns processes and catalysts for manufacturing vinyl chloride monomer (“VCM”) from acetylene.
  • VCM vinyl chloride monomer
  • the mercury catalyst usually 8-10% mercuric chloride on activated charcoal, used in the original process is highly toxic. Such toxicity creates problems arising from handling during manufacture of the catalyst as well as during loading of catalyst and removing catalyst after a campaign.
  • a campaign is generally of six month duration. Deactivation of the mercury catalyst and loss of HgCI 2 by sublimation or volatilisation from the reactor in use can be significant problems.
  • the ethyne process using mercury-based catalyst requires a lower capital investment in plant than the ethylene process; if a non-volatile and less toxic catalyst could replace the mercury catalyst without requiring significant plant alterations in existing plant designs, this would be a significant advantage.
  • the preparation of the catalyst is not described, and no commercial use of the process or the catalyst appears ever to have taken place.
  • the present invention provides a process for reacting ethyne with HCI, comprising passing the reactants over a catalyst comprising metallic gold particles, suitably gold nanoparticles, carried on a carbon support.
  • the invention also provides a gold-based catalyst for the process of the invention, comprising a carbon support and metallic gold particles, suitably gold nanoparticles.
  • nanoparticles we mean metal particles having a diameter within the range 1 - 1000 nanometres.
  • the catalysts of the invention may be considered to comprise gold particles having a core comprising metallic gold and a shell or surface layer comprising higher oxidation state gold species including Au 3+ .
  • the shell need not be complete, but preferably all or substantially all the exposed surface of the particle has the surface higher oxidation state gold species; for example if the metallic gold is partially surrounded by carbon, the "shell" may extend only over the exposed particle surface.
  • Au 3+ need not be the only higher oxidation state gold species present in the shell, and Au 1+ may also be present, for example.
  • Such higher oxidation state species may be stabilised by halide.
  • the core comprises metallic gold (Au 0 ) but other gold species may also be present in the core.
  • the metallic gold in the core and the Au 3+ and/or other positive oxidation state species in the shell act as a redox couple, or the metallic gold core acts as an electron sink during the desired reaction(s).
  • the gold particles are desirably dispersed over the surface of the carbon support, when the catalyst is fresh. After a period of use, the gold particles may especially be carried on carbon fibrils.
  • the carbon fibrils may be carbon nanotubes.
  • the catalysts of the invention have never previously been observed or described. In contrast to prior observations that coking of gold catalysts causes deactivation, we believe that rather than active gold catalyst particles being submerged under coke-type masses, in the present invention the carbon fibrils carry the catalytic gold particles in such a manner that they remain active and exposed to the reactants.
  • the catalysts of the invention may be prepared starting from a high surface area activated carbon, preferably of surface area greater than 800 m 2 /g, such as a 1300 m 2 /g carbon extrudate.
  • a high surface area activated carbon preferably of surface area greater than 800 m 2 /g, such as a 1300 m 2 /g carbon extrudate.
  • Other carbon supports including powders or granulates or other forms of carbon may be used. Such materials are commercially available.
  • washing for example an acid wash, may be applied, preferably using hydrochloric acid. It has been found that, if necessary, dispersing the carbon in 3% hydrochloric acid, bringing to the boil, draining, and washing with distilled or deionised water, is effective.
  • Carbon extrudates are available as "high purity” or “ultra high purity” grades commercially and such grades are typically acid washed to remove impurities.
  • Catalysts may be prepared using a variety of catalyst preparation techniques known generally in the art, for example impregnation, preferably using incipient wetness methods, deposition, precipitation and combinations of these.
  • the gold may be applied to the carbon from gold precursors such as HAuCI 4 . xH 2 O salt or from an aqueous solution or by dissolving metallic gold or other precursor in a mixture of nitric acid and hydrochloric acid such as that commonly known as "aqua regia” then adding the solution to the carbon particles or extrudates or vice versa. It has been observed when using an aqua regia solution that the carbon turns a gold colour then within a few seconds, turns a dark brown/black, and an evolution of NOx fumes was noted.
  • an aqua regia solution Whilst we do not wish to be bound by any theory, it is thought that the gold is initially deposited as a gold salt, and that the salt is reduced to metallic gold by the active carbon but either retains or forms a shell comprising the higher oxidation state species, including Au 3+ , where exposed to the aqua regia solution.
  • the impregnated support may be washed following impregnation to remove excess aqua regia solution in order to reduce the amount of NOx fumes generated during drying. We have, however found that catalyst activity may be reduced in this manner and so it is not presently preferred to include this washing step after impregnation.
  • the gold particles are preferred to comprise substantially 100% gold, but it is contemplated that alloys and/or composites may also be active catalysts for the reactions of interest. Possible alloys and/or composites may include Cu and/or Ag, which may also exhibit the effective higher oxidation state surface species.

After the exotherm had subsided, the temperature was raised to 18O 0 C and the hydrogen chloride treatment was continued for one hour.
