庄庆发,研究员,博士生导师,加拿大工程师协会会士,加拿大工程院院士。2018年全职引进在多相催化转化研究组工作,现重点开发以木质纤维素为原料,通过悬浮床木油共炼技术实现生物质资源的高效解聚,进而通过超临界萃取等提质技术合成高品质动力燃料、合成润滑油及基础化学品。
主要研究领域和学术成就:
提出重质油开发和加工利用上下游一体化技术是重质油加工领域的重要技术突破,是目前世界上最新的重油改质技术,重质油开发和加工利用上下游一体化技术包含两个核心技术,一是重油深度选择性脱沥青质技术(SELEX-Asp),该技术是从重质原油或渣油中脱除固态沥青并回收渣油中所需的组分,取代了传统炼油工艺的焦化过程,是一个低温分离工艺,无气体产生,与传统的焦化工艺相比可多获得3-5 wt %的液体产品,每吨原油的收益将增值100-200元,低温工艺不但节能,而且还可以减少空气的硫污染;二是采用喷雾造粒分离回收溶剂和残渣与重油的超临界流体萃取相耦合的技术,将传统的沥青残渣与溶剂的高温气液分离过程转化为低温气固分离(100℃),去掉了沥青高温加热炉,可处理高软化点(>150℃)沥青,突破了传统的溶剂脱沥青过程制约脱沥青油收率的技术瓶颈。
所提出的重质油和油砂沥青开发和加工利用上下游一体化的技术方案,以戊烷及其馏分为溶剂,脱沥青油收率高,对中质和重质减压渣油的总脱沥青油收率可达70-85m%,得到的脱沥青油性质较好,可脱除对轻质化加工有害的全部沥青质、50%以上残炭和70%以上重金属,显著降低粘度,并可灵活的将脱沥青油梯级分离几个不同馏分,从而大幅度地改善重油的轻质化加工性能。
目前已发表130余篇期刊论文,120篇研究报告和获得18项发明专利。
