  • Catalyst for MWCNT production
    Patent number: 11826732
    Abstract: An iron-free supported catalyst for the selective conversion of hydrocarbons to carbon nanotubes may include cobalt and vanadium as active catalytic metals in any oxidation state on a catalyst support comprising aluminum oxide hydroxide. The mass ratio of cobalt to vanadium is between 2 and 15; the mass ratio of cobalt to aluminum is between 5.8 10?2 and 5.8 10?1; and the mass ratio vanadium to aluminum is between 5.8 10?3 and 8.7 10?2. The present disclosure is further related to a method for the production of this iron-free supported catalyst and to a method for the production of carbon nanotubes using the iron-free supported catalyst.
    Type: Grant
