Abstract

A process for dedusting a dust laden vapor gas mixture (VGM) obtained by pyrolysis of a material containing hydrocarbons includes treating the dust laden VGM in a dry electrostatic precipitator at a temperature in a range from 380 to 480° C. so as to separate dust from the VGM. Then, the VGM is cooled to a temperature in a range from 310 to 360° C.
