Abstract
The invention relates to the oxidative treatment of bulk material in a vessel. The bulk material to be treated is placed in the vessel, and is humidified therein with water or an aqueous solution to such an extent that it can be treated with an O2/O3 gas mixture in such a way that the desired end product has a determined pH value or a determined solubility or a determined polarity or a determined solubility behaviour and/or particle size distribution. The inventive method enables bulk material to be very effectively oxidised by means of minimal amounts of ozone in an O2/O3 gas mixture, in such a way that between 70 and 100% of the ozone parts enter into a reaction.
