METHOD FOR DEPOSITION OF NOBLE METAL NANOPARTICLES ON CATALYSTS TO PROMOTE SAME, AND THE COMPOSITIONS SO PRODUCED

摘要

A method for promoting the supported catalysts using noble metal nanoparticles. Different noble metal precursors are preferentially deposited onto the supported metal catalysts through Chemical vapor deposition (CVD), and compositions so produced. Further, the promoted catalyst is used for CO and CO2 hydrogenation reactions, increasing the reaction conversion, C5+ compounds selectivity and chain growth probability. The active phase of catalyst can be either cobalt oxide, nickel oxide or their reduced format (Co0 or Ni0), and the noble metal is preferably Ruthenium.

1. A method for producing a catalyst comprising:
depositing noble metal nanoparticles onto active metal surfaces of a precursor catalyst, wherein said noble metal nanoparticles are deposited onto the active metal surfaces using chemical vapor deposition, wherein the temperature for said depositing is within the range of about 150° C. to about 200° C., whereby said chemical vapor deposition of said noble metal nanoparticles minimally deposits upon support surfaces for said catalyst.
