摘　　要：采用新型的脱硫试剂 (Ni2 B)对富硫原油沥青质中含硫结构单元的研究结果表明 ,沥青质脱硫产物以饱和烃为主 ,包括丰富的正构烷烃系列和环状生标系列。沥青质脱硫产物类似于原油饱和烃的分布。通过计算得到了沥青质脱硫饱和烃及其环状生标的参数 ,这些参数与原油饱和烃的相应参数比较接近 ,这表明沥青质中的含硫结构单元可能是原油饱和烃的先质。A novel desulphurizing agent, nickel boride (Ni\-2B), was used to study the sulfide linkages in sulphur-rich asphaltene. The products from Ni\-2B reduction of asphaltene were dominated by saturated hydrocarbons including large numbers of n-alkanes and cyclic biomarkers. The parameters of biomarkers in the products are similar to those of saturated hydrocarbon in crude oil, which indicates that these organic sulphur compounds in asphaltene may be the precursor of hydrocarbons.
