Development of a Coal-Based Carbon Black

Abstract

In recent years, coal tar and natural gas have been used for the production of carbon black. The production process is complicated, the equipment is large, the energy consumption is high, the recovery rate is low, and the price of carbon black is relatively high. The coal-based carbon black is prepared by using raw coal as a raw material to replace tar and natural gas. Raw coal has rich raw material resources, simple preparation process, low investment, and low cost. First of all, the raw coal is pretreated to remove gangue, iron wire, sawdust and other magazines, sorting to get clean coal, then add chemical reagents ultra-fine grinding, and then high-temperature calcining to remove the coal magazine to make it pure carbon material, coal obtained after crushing Carbon black, the resulting coal-based carbon black has a good process properties. The elemental analysis, infrared absorption spectrum test, Zeta potential measurement and transmission electron microscopy test characterization and the existing carbon black species on the market are compared, there is no big difference in performance. It can be confirmed that using raw coal as raw material to prepare coal-based carbon black can meet the technical requirements. To meet the market demand, replace tar and natural gas, no pollution of three wastes, protect the environment, has a high research value.
