Recovered Carbon Black from waste tire pyrolysis

Recycling is more important than ever, but not easy. How different are the interaction properties of recovered carbon black (rCB) to new CB? Can we optimize the influence of pyrolysis parameters on rCB characteristics and their consequent effect on its in-rubber performance ?

The use of recovered Carbon Black (rCB) alone can reduce the size of the carbon footprint by 80%, which is why, overs the years, rCB became a major topic and nowadays many industries are specialized to bring back to life end-of-life tires. Indeed, they represent a source of oil, gas, steel and carbon black.

At Adscientis, we contribute to this development by using Inverse Gas Chromatography (IGC) to determine the interactions capabilities of rCB and also the efficiency of the pyrolysis process.

To do so, our IGC instruments at Adscientis have been used to characterize the new and recycled carbon black qualities thesis at the University of Twente, NL (2021) by Arqam Anjum during his PhD thesis. The interesting thesis is publicly available, you can read by clicking on the button below !

The interaction and surface properties have been studied in detail by IGC using dynamic gas adsorption of 15 different molecular probes. The detailed results and its interpretation are found on pages 105 - 135. Be inspired by this recycling approach and the potential of detailed surface analysis by IGC.
