The secondary aluminum ash (SAA), carbide slag (CS) and carbon black (CB) were provided by Yunnan Coal Chemical Industry Group Co., ltd. 2.2. Preparation of SAA@CS-CB. Certain amounts of secondary aluminum ash, carbide slag as well as carbon black were weighed and put into a vacuum drying oven and dried at 60 ℃ for 12 h.
A sustainable and green method is presented in this paper to produce highly oxidized carbon black using dry ball milling. The mechanical energy by colliding milling balls is able to easily break an...
The residues after waste tire pyrolysis were first sieved to remove ash components and ground into powder (~80 μm). The resulting waste tire carbon blacks (TCB) processed by regular dry or wet milling with the help of compatible solvent can only produce particle sizes around 250 nm. ... Carbon black preparation, chemical milling …
Removal efficiency of impurities from waste tire pyrolytic chars. The properties of pyrolytic chars from waste tires were shown in Table 1. All of the six kinds of waste tire pyrolytic chars show the carbon content higher than 70%, indicating their possibility to be used as carbon black, which is also consistent with those published …
