摘要
在对国外 5种减压渣油进行超临界流体萃取分馏及其窄馏分性质分析的基础上 ,考察了已有的渣油特征化参数KH 对国外减压渣油的适用性。研究结果表明 ,已有的渣油特征化参数KH 和国外减压渣油的化学组成偏差较大。因此 ,笔者建立了一个新的渣油特征化参数KR,可以比较准确地关联国内外 11种渣油馏分的性质和组成 。
Five foreign residues were deeply cut into a number of narrow fractions by supercritical fluid extraction and fractionation technique, whose properties and compositions were fully analyzed to provide a data base for characterization. The existing characterization KH index was found to deviate largely from their chemical compositions when applied to foreign residues. A new index KR was established, which was found to correlates accurately to the properties and compositions of eleven domestic and foreign residues, the FCC and thermal cracking reactivity of fraction was characterized as well.
