    摘要: Lubricant base oils are made up essentially of 2 - 15% by weight of a total aromatics content, greater than 60% by weight of isoparaffins and monocyclic naphthenes in total, more than 30% by weight of alkylbenzenes in the total aromatics content and smaller than 4% by weight of tricyclic and tetracyclic aromatics in the total aromatics content. The base oil has great viscosity index, small pour point, high oxidative stability and heat stability and sufficient capability to dissolve sludge.
