摘要

本研究对废轮胎热解产生的粗炭黑的处理进行了研究，以评价其质量和可能的工业应用。对具有代表性的粗炭黑样品进行了干筛，确定了初始粒度分布。然后将粗炭黑粉碎，在热浓硫酸中浸出，去除重金属和其他污染物。对精制炭黑的分析表明，与粗炭黑相比，产品质量有显著提高。研究发现，精制炭黑可进一步分类为多种高价值产品，可用于各种工业用途，如填料、油漆颜料、活性炭和燃料型煤。关键词:活性炭，型煤，燃料，填料，热解

Beneficiation of Pyrolitic Carbon Black

This research investigated treatment of crude carbon black produced from pyrolysis of waste tyres in order to evaluate its quality and possible industrial applications. A representative sample of crude carbon black was dry screened to determine the initial particle size distribution. This was followed by pulverizing the crude carbon black and leaching in hot concentrated sulphuric acid for the removal of heavy metals and other contaminants. Analysis of the refined carbon black showed a significant improvement of the product quality compared to crude carbon black. It was discovered that refined carbon black can be further classified into multiple high value products for various industrial applications such as filler, paint pigment, activated carbon and fuel briquettes. Keywords—Activated Carbon, Briquettes, Fuel, Filler, Pyrolysis.
