Effect of Dual Acid Treatment Assisted by Ultrasonication Technique on Recovered Carbon Black Derived from Waste Tire

Abstract

The abundance of waste tires creates significant environmental and health problems. One way to address this is through pyrolysis, which breaks down waste tires into gas, oil, and recovered carbon black (rCB). rCB has many potential uses, but it often contains impurities that lower its quality compared to new carbon black. This study used dual-acid washing to improve rCB quality by reducing ash content and enhancing its surface properties. This improvement could make rCB more useful in various products, helping to reduce waste and pollution from tire disposal.
