Example Embodiment
[0023] Example 1
[0024] It includes the following steps:
[0025] S1: The scrap tires from which the iron wire is removed are crushed to obtain scrap tires;
[0026] S2: Pass the waste tire residue through the screening machine and enter the grinder for full grinding; after grinding, enter the activator for activation;
[0027] S3: Add organic solvent, desulfurizing agent, sulfuric acid to the activator, and react at 60 degrees Celsius for 30 minutes; the organic solvent includes a mixed solvent of ethanol, ethanolamine and benzene; the desulfurizing agent in S3 is zinc chloride, chlorine A mixture of one or more of iron and aluminum chloride; the mass ratio of desulfurizer to waste tire slag is 5:17;
[0028] S4: Carbon black is made from the activated waste tire residue by catalytic cracking method;
[0029] S5: After the carbon black is dried, an alkaline agent is added. The reaction temperature is 60 degrees Celsius and the reaction time is 1-2h; then the neutralization is perform...
