Figure 11 Temperature profile comparing all cases.
Temperature profiles were also obtained, and, like the pressure
profiles, the curves obtained for all cases showed extreme similarity
with practically overlapping points. There were temperature peaks
between 94 and 98ºC at the beginning of the reaction, but over time this
temperature stabilized reaching the initial value of 70ºC. The highest
peak presented was that representing case 2 and the lowest peak
represents case 4.
Observing the pressure and temperature profiles, it is observed that the
number of active centers does not influence the reaction profiles.
Considering that the pressure drop is basically the consumption of
monomer during the reaction, it can be inferred that the conversions of
the four simulations are very similar, while from the temperature
profiles, despite the active sites have different kinetic constants, the
exothermicity of the reaction remains largely unchanged.
