    Abstract: 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.

    Abstract translation: 本公开设想了一种通过以0.1:2至2:1的比例混合炭黑粉末和水与粘合剂和分散剂来造粒炭黑的方法。 分散剂是胺基表面活性剂，并且以总混合物的0.005-0.1％的比例加入。 将混合物在造粒机中造粒，随后将原料颗粒在150-250℃之间的温度下干燥20-60分钟，得到炭黑颗粒。 本公开的方法提供了在颗粒表面上均匀分布的水分，其具有均匀的颗粒质量，减少的水消耗，节能和提高的生产率。

    Abstract: The present invention discloses an adsorbent comprising a densified carbon black. The densified carbon black comprising the adsorbent preferably has an increase in density of from about 100% to about 500% above the undensified form of the adsorbent. The densified carbon black adsorbent has an increase in adsorption capacity per unit volume over the undensified form of the adsorbent in excess of 100%. The densified carbon blacks are particularly useful as adsorbents for gases.
