The micro-scale thermo-gravimetric results show that pyrolysis kinetics of waste tyres can be regarded as the linear accumulative total of each elastomer (NR, BR or SBR) as well as their process oils, and the range of reaction is from 250℃ to 520℃, which implies that the kinetics is rarely dependent on the heating.

废轮胎热解实际上是其组成胶体NR、BR、SBR和相应操作油的挥发过程,因此,其动力学模拟方法倾向于采用各种胶体成分热解动力学叠加的多组分模型。

In this article,oil based adjuvants including petroleum oils,vegetable oils and their derivatives were introduced:their mode of action,verities and applications in herbicides.
