摘要
用热重分析法研究了减压渣油的热转化行为,获得了渣油热转化的起始失重温度、转化终了温度、剧烈反应温度区间、反应速率峰值及峰值温度、生焦率、不同转化阶段的温度区间及对应的动力学参数和动力学方程.该方法具有简便易行,样品用量少,取得参数多,获得信息快等优点。
The influences of chemical composition of asphalt, solvent and ratio of sulfurate agent on the performance of product were investigated. The results show that the chemical composition of asphalt is an important factor for affecting the performance of sulphonated asphalt. The chemical composition of solvent affected the state of asphalt solvent system and properties of the product.
