摘要
石油资源紧张和油价不断飙升促使各国越来越重视废油的回收利用,根据大力发展循环经济的要求,我国的废油再生技术及工艺正逐步向着环保、高效、经济的趋势发展。文章从溶剂精制、超临界流体萃取、絮凝沉降三个方面综述了国内外基于溶剂过程的废油再生技术及工艺的研究进展,文章在对当前国内外废油再生技术及工艺分析研究的基础上,展望了我国废油再生处理关键技术的研究趋势。
For decreasing petroleum resource and soaring oil price,more and more attention is being paid to regeneration of waste oils in every country.With regard to the demand of cyclic economy in our country,technologies employed in recycling are becoming environmentally friendly,efficient and economic.The technologies and technics on regeneration both at home and abroad are summarized in this paper,and especially,the solvent refining,supercritical fluid extraction and flocculation-sedimentation are described in detail.In the end,the research trends of key technologies of regeneration in China are predicted.
