TEMPERATURE DISTRIBUTION IN A PLASMA PILOT REACTOR FOR CARBON BLACK PRODUCTION

Abstract

The conception and optimisation of high temperature plasma process for carbon blacks synthesis from hydrocarbons by pyrolysis is the objective of an European industrial association.
To control the process by correlating the operating conditions and the product properties, it is necessary to examine the internal behaviour of the reactor and more particularly the temperature field in the plasma flow and along the reactor wall.
Typical emission spectroscopy and optical pyrometry results are presented in this paper, including: evolution and distribution of plasma temperature inside the reactor obtained by analysis of C2 Swan band and of wall temperature. Experimental temperature distribution is then compared with numerical simulation data including electromagnetic forces, fluid dynamics and heat transfer.
