【摘要】大港减压渣油被超临界萃取技术分馏成F1~F16个级分。用商品级的石蜡作为外标,用GC/MS对这些级分进行定性和定量分析,分析结果显示,用GC/MS检测的主要成分为C15到C43的直链烷烃、包含藿烷、萜烯和含氧有机化合物等,这些化合物的浓度从F1到F16明显减少。HPLC/MS将被用来分析级分中分子量大、极性大的物种的分子组成。更多还原

【Abstract】 Dagang vacuum residue（DVR） from vacuum distillation of Dagang crude oil,one typical Chinese crude oil,was separated into sixteen fractions denoted as F1 to F16 by SFE technique.The fractions were subject to qualitative and quantitative analyses with GC/MS using a commercially available paraffin as a reference standard.The results show that main components detected with GC/MS are normal chain alkanes from C₁₅ to C₄₃,and cycloalkanes including hopanes and terpanes along with small amounts of alkenes,arenes and oxygen-containing organic compounds.The concentration of the compounds decreases remarkably from F1 to F16.HPLC/MS analysis will be conducted to analysis molecular composition of heavier and more polar species in the fractions.更多还原
