1. A process for dedusting a dust laden vapor gas mixture (VGM) obtained by pyrolysis of a material containing hydrocarbons, the process comprising:
- 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; and
after removal of the dust in the electrostatic precipitator;
cooling the VGM;
directing the VGM to at least one further electrostatic precipitator; and
treating the VGM in the at least one further electrostatic precipitator at a temperature selected so as to separate a predetermined fraction of the oil.

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.
