A further analysis using the Arrhenius equation and experimental values of apparent rate constants allowed predicting the time to reduce in two log units the viability of C26 at five different temperatures (Figure 3b) (Sorokulova et al.
Set-4--the kinetic parameters of pyrolysis (initial temperatures of kinetic and diffusion regime, final temperatures of kinetic and diffusion regime, pre-exponential factor from Arrhenius equation for kinetic and diffusion regime, activation energy for kinetic regime).
In order to simulate the effect of high mechanical shear stress in the ultrahigh speed TSE at high speed and have a qualitative analysis on the difference between thermal and mechanical effects on the depolymerization of the PS, we used the prefactor and activation energy values determined for the Brabender batch mixer experiment (with only thermal effects) in the Arrhenius equation with the depropagation rate constants for the reactions occurring at different screw speeds in TSE.
Diffusion coefficient, D, the amount of a particular substance that diffuses across a unit area in unit time, often obeys the activated transition state theory and its temperature dependence can be expressed by the Arrhenius equation, (22), (23) equation (1):
A simplified Arrhenius equation and a resulting reliability plot against operating temperature are displayed in FIGURE 2.
1]) clearly indicated that the thermal process were adaptable the Arrhenius equation (Fig.
The effect of T on the kinematic viscosity of liquid is described by means of the Arrhenius equation (1) which describes the exponential decrease of kinematic viscosity versus T [8,9,10]:
The rule of thumb, based upon the Arrhenius equation, is that a 10[degrees]C temperature rise translates to a twofold increase in reaction rate.
3), according to Arrhenius equation, the expression of reaction rate constant k is as follows:
