A method of catalyst preparation that can increase the performance and stability to deactivation of metal-supported catalysts.

Technology Summary

Many industrial catalysts tend to form carbon and sinters and to deactivate too quickly. Prof. Eduardo Wolf has developed a novel method of catalyst preparation, known as pressure dilution, that increases catalyst stability and extends usable capacity over 8 times longer. 

In particular, the process has been used to prepare a metal-supported catalyst (10% Ni) for use in dry reforming of methane reactions. The resulting pressure diluted catalyst pellets are more stable and possess three times higher dispersion than original undiluted pellets. The greater dispersion yields higher activity and stability for the reaction in which it was tested. As an example, in typical dry reforming of methane reactions, catalysts typically deteriorate in 8 hours. However, when a catalyst prepared from Dr. Wolf’s method was tested it was able to perform the reaction for more than 70 hours without deactivating. The pressure dilution method can be applied to the preparation of many metal-supported catalysts used in the petroleum and petrochemical industries.

Market Advantages 

  • Produces catalysts with over 8 times better stability (longer duration to deactivation)
  • Produces catalysts with up to 3 times greater dispersion
  • Method should be applicable to other metal-supported catalysts.
