A PROCESS FOR THE PREPARATION OF CARBON BLACK PELLETS

摘要

The present invention envisages a process for pelletizing carbon black by mixing carbon black powder and water in a proportion in the range of 0.1 : 2 to 2 : 1 with a binding agent and a dispersing agent. The dispersing agent is an amine-based surfactant and is added in a proportion in the range of 0.005 - 0.1 % of the total mixture. The mixture is pelletized in a pelletizer and subsequently the raw pellets are dried for 20 - 60 minutes at a temperature between 150 - 250 °C, to obtain the carbon black pellets. The process of the present invention provides uniform distribution of water on the surface of the pellets giving a uniform pellet quality, reduced water consumption, energy savings and an increased production rate.
