How Dried Oily Sludge Breaks Down at High Temperatures

What is it about?

Oily sludge, a waste product, can be effectively utilized in a process called pyrolysis, which helps recover valuable products and reduces harmful emissions. To make the pyrolysis process commercially feasible, it is important to understand the thermo-kinetic behavior of the reactions involved. This study analyzed the thermal degradation behavior of dry oily sludge using two different methods: the Friedman and Vyazovkin method (model-free approach) and the Coats-Redfern method (model-fitting approach). The analysis was conducted using thermogravimetric analysis (TGA) at different heating rates. The results showed that the maximum conversion occurred in the 20-60% conversion range, and the overall activation energy and thermodynamic parameters decreased as the conversion increased. The study provides valuable insights into the kinetics and thermodynamics of the pyrolysis process, which can help improve the quality and yield of products and make it feasible for commercial-scale implementation.
