Abstract

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. Under optimal process conditions (120 A current, 2.0 bar injection pressure), plasma-derived CB exhibited enhanced properties with a surface area of 89.2 m²/g (vs. 74.3 m²/g for conventional N330) and an iodine adsorption number of 90 mg/g (vs. 75 mg/g for N330), demonstrating superior performance potential for rubber reinforcement, energy storage, and catalytic applications. By optimizing parameters, this method offers an eco-friendly, efficient alternative for tailoring CB properties, advancing sustainable industrial applications.

等离子体辅助热解燃料油合成具有增强表面积和结晶度的炭黑：优化工艺参数

本研究提出了一种基于等离子体的可持续方法，以热解燃料油（PFO）为原料合成炭黑（CB），这是一种源自废物的原料，与传统的能源密集型炉工艺相比。将PFO注入等离子体羽流中，我们改变电流和注入压力来评估对炭黑特性的影响。高级分析（拉曼、BET、TEM）表明，更高的电流产生更小、更多的结晶颗粒，而增加的压力增加了表面积，但减少了结晶。在最佳工艺条件下（120 A电流，2.0 bar注射压力），等离子体衍生的CB表现出增强的性能，其表面积为89.2 m²/g（传统N330为74.3 m²/g），碘吸附量为90 mg/g（传统N330为75 mg/g），在橡胶增强、储能和催化应用方面表现出优异的性能潜力。通过优化参数，该方法为定制CB特性提供了一种环保、高效的替代方案，促进了可持续的工业应用。

期刊介绍： ChERD aims to be the principal international journal for publication of high quality, original papers in chemical engineering. Papers showing how research results can be used in chemical engineering design, and accounts of experimental or theoretical research work bringing new perspectives to established principles, highlighting unsolved problems or indicating directions for future research, are particularly welcome. Contributions that deal with new developments in plant or processes and that can be given quantitative expression are encouraged. The journal is especially interested in papers that extend the boundaries of traditional chemical engineering.
