Abstract:
Provided is a method of production of catalyst support particles, containing zirconium dioxide and optionally silicon oxide, comprising the steps: (i) preparation of a solution containing precursor compounds of zirconium dioxide and optionally of silicon dioxide, (ii)conversion of the solution to an aerosol, (iii)bringing the aerosols into a directly or indirectly heated pyrolysis zone, (iv) carrying out the pyrolysis, (v)separation of the catalyst particles formed from the pyrolysis gas.
