TEMPERATURE DISTRIBUTION IN A PLASMA PILOT REACTOR FOR CARBON BLACK PRODUCTION

摘要

The conception and optimization of high temperature plasma process for carbon blacks synthesis from hydrocarbons by pyrolysis is the objective of a European industrial association. To control the process by correlating the operating conditions and the product properties, it is necessary to examine the internal behavior 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 C_(2) Swan Band and of wall temperature. Experimental temperature distribution is then compared with numerical simulation data including electromagnetic forces, fluid dynamics and heat transfer.
