摘要
随着环保形势的日益严峻以及高端炭材料对原料沥青中硫、氮元素含量的严苛要求,导致高硫、氮沥青的应用受到了极大的限制,因此降低沥青中硫、氮元素的含量非常必要。基于沥青中硫、氮的赋存形态,从加氢法和溶剂法两个方面论述了沥青中硫、氮元素脱除的研究进展,并对沥青中硫、氮元素脱除技术的发展方向进行了展望。
With the increasingly severe environmental protection situation and the strict requirements of high-end carbon materials on sulfur and nitrogen content in raw pitch,the application of pitches with high sulfur and nitrogen content is greatly limited.Therefore,it is necessary to remove the sulfur and nitrogen in pitch.Based on the occurrence forms of sulfur and nitrogen in pitch,this paper discusses the research progress of sulfur and nitrogen removal technology from pitch as well as the future research direction and technical development of sulfur and nitrogen removal technology of pitch.
