Study of Carbon Black Production with Optimized Feed to Predict Product Particle Size
Volume 4, Issue 1 , January 2007, , Pages 36-42

Abstract
  Carbon black or soot is a carbon rich material which is widely used as a modifier and filler. Usually carbon black is produced via thermal decomposition of heavy hydrocarbons. This process is too complex to be modelled fundamentally. In this study, the effect of reaction feed composition on the soot ...  Read More
