PROBLEM TO BE SOLVED: To provide a process and a device for the extraction of substances from silane-modified fillers. SOLUTION: At least one gas compressed by means of pressure and/or temperature is employed as an extraction agent and the compressed gas is led in the radial direction through the filler in the pressure container and/or the substances extracted from the silane-modified filler are removed from the compressed gas with a suitable sorbent. By this invention, substances can be effectively extracted from silane-modified fillers, and at the same time, a high throughput of compressed gas passing through the bulk bed of filler is made possible.
