    摘要： The present disclosure 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 disclosure 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.

    摘要： A process for production of a modified carbon black, at a cheaper cost, for rubber reinforcement having the superior tan null temperature dependency of silica and an excellent abrasion resistance and further having no problems arising due to a low electrical conductivity is provided. In the process for production of a modified carbon black for rubber reinforcement wherein, in the step of granulating the carbon black, a water-dispersed silica is added to the carbon black, the granulating is performed by a granulator and a process of production of a rubber composition containing a surface-treated carbon black for rubber reinforcement comprising coagulating, with a coagulating agent, a mixture of (a) 100 parts by weight, as a solid content, of a diene rubber component and (b) 10 to 250 parts by weight, as a solid content, of a slurry containing a carbon black for rubber reinforcement or (bnull) 10 to 250 parts by weight of a modified carbon black produced by the above method.
