摘要：以对比研究的方法,应用成焦板试验、热管氧化试验等手段考察了传统的溶剂精制工艺生产的基础油和加氢异构脱蜡工艺生产的基础油的高温清净性及添加剂作用规律,并对油品在成焦过程中的抗氧化性能、总碱值以及沉积物的结构组成变化进行了研究。结果表明:结构组成不同导致两种基础油高温清净性和添加剂感受性存在显著差异;两种基础油在成焦过程中的抗氧化性能和添加剂消耗表现出各自的规律性;实验结果和FT-IR分析表明金属盐类(包括清净剂析出的碳酸盐)和反应过程中生成的羧酸盐类和硫酸盐在成焦过程中都会沉积在金属表面。
Coking test and hot tube test were used to study the high temperature detergency and additives action rules of solvent-refining base oil from the conventional process and hydrogenation-isomerization dewaxed base oil from the most advanced process by means of contrast research. Anti-oxidation properties, the changes of total base number and carbonaceous deposit structure during the coking test were (also) studied. The results indicate that the high temperature detergency and additive sensitivity of two base oils are obviously different, which are caused by their different structures; the two base oils show their own antioxidation properties and additive consumption rules respectively in the course of coking test; test results and analysis by FT-IR indicate that metallic salts including carbonate, sulfate and carboxylate (deposited) on metal surface under the simulation test conditions.
