Abstract
The present invention relates to a pyrogenic process for manufacturing metal oxides or metalloid oxides wherein a metal precursor and/or a metalloid precursor is introduced into a flame formed by burning a gas mixture comprising oxygen and hydrogen, wherein at least a part of the hydrogen has been obtained from electrolysis of water or an aqueous solution, using electrical energy, at least a part of which has been obtained from a renewable energy source, and wherein at least a part of the thermal energy of the flame is transferred to a first heat transmission medium by means of at least one exchanger, thereby heating the first heat transmission medium to a maximal temperature in the range between 8° and 150° C.
Claims14
A process for manufacturing a metal oxide or a metalloid oxide, comprising the following:
- (a) introducing a metal precursor and/or a metalloid precursor into a flame,
- wherein the flame used in (a) is formed by burning a gas mixture comprising oxygen and hydrogen,
- wherein at least a part of the hydrogen has been obtained from electrolysis of water or an aqueous solution, using electrical energy, at least a part of which has been obtained from a renewable energy source,
- (b) transferring at least a part of the thermal energy of the flame used in (a) to a first heat transmission medium by at least one exchanger, thereby heating the first heat transmission medium to a maximal temperature in a range between 8° and 150° C.
