Plasma-Assisted Synthesis of Carbon Black with Enhanced Surface Area and Crystallinity from Pyrolysis Fuel Oil: Optimizing Process Parameters

This study presents a sustainable plasma-based method to synthesize carbon black (CB) from pyrolysis fuel oil (PFO), a waste-derived feedstock, contrasting traditional energy-intensive furnace processes. Injecting PFO into a plasma plume, we varied current and injection pressure to assess impacts on CB properties. Advanced analyses (Raman, BET, TEM) showed higher currents yield smaller, more crystalline particles, while increased pressure elevates surface area but reduces crystallization. Plasma-derived CB demonstrated a higher surface area than conventional N330, indicating superior potential in rubber, energy storage, and catalysis. By optimizing parameters, this method offers an eco-friendly, efficient alternative for tailoring CB properties, advancing sustainable industrial applications.
