Modification of oil sludge by highly dispersed carbonaceous additive

摘要

The effect of modification of tar by highly carbonaceous additives on the rate of the oxidation process and the quality of oxidized bitumen has been studied. The dependences of the softening temperature of bitumen from the oxidation time have beenobtained. Penetration, penetration index of oxidized bitumen modified with highly carbonaceous additives tar fractions have been determined. The relaxation characteristics of oxidized bitumen: dependences of the relaxation time and the width of the temperature range of the duration of the process of oxidation have been obtained. It has been established that the rate of the process of obtaining oxidized bitumen increases with the number entered modifier by reducing the induction period.
