High-Pressure Partial Oxidation is a key technology for the usage of flare gases and heavy oil residues. At the test plant of TU Bergakademie Freiberg, it is possible to gasify different gaseous and liquid fuels at pressures up to 100 bar (g). Information on residence time distributions can be gained by using radioactive tracers. The results of measurements for different reactor geometries and feedstocks will be discussed in this paper. Results of radioactive residence time measurements depend strongly on reactor geometry and require different evaluation methods.
