PROCESS FOR PERFORMING A PYROLYSIS OF HYDROCARBONS IN AN INDIRECTLY HEATED ROTARY DRUM REACTOR

摘要

The present invention is directed towards a process for performing a pyrolysis of hydrocarbons in a rotary drum reactor at a temperature in the range of from 600 to 1800°C, whereas the heat for the endothermic pyrolysis is provided by resistive heating of at least one particulate electrically conductive material introduced into said rotary drum reactor and moved through the rotary drum reactor with a flow of a hydrocarbon, wherein said rotary drum reactor contains of the following elements: (A) an inner wall made of electrically insulated material, (B) a pressure-bearing outer wall (C) with an electrical heating system attached to the inner wall and/or at least one integrated electrically conducting electrode pair, wherein at least one electrode is located at both ends of the inner wall of the rotary drum.
