Method for odor reduction of particulate carbon materials

A method for producing an odor-reduced particulate carbon material, the method comprising:

• in a first process step precipitating a starting material wholly or partly dissolved in a liquid to obtain a particulate carbon material,
• treating the particulate carbon material subsequently in a second process step by heating in a gas atmosphere and a process temperature, whereby the odor-reduced particulate carbon material is produced,
• wherein in the second process step the process temperature does not exceed a maximum temperature of 300° C. and does not fall below a minimum temperature of 150° C. and
• wherein the gas atmosphere in the second process step is selected from:
• (a) an enriched air comprising one or more inert gases, which has an oxygen content of less than 15% by volume, and/or
• (b) a pressure-reduced air with a pressure of less than 500 mbar.
