“…A BBD design of this experiment, but with different independent variables and waste plastic mixture as the feedstock, was recently described [39]. Moreover, Ore and Adebiyi [40] chose a similar experimental design and a related RSM in studying the effects of temperature, sample weight, and reaction time on the yield of non-condensable gases in the pyrolysis of waste tire in a fixed-bed reactor.…”

“…In order to examine the aforementioned assumptions to mathematically describe and quantify each of them, the Box-Behnken design was used as a specific type of response surface methodology (RSM). RSM is commonly applied in the description of various processes [30][31][32][33], especially in the description of the pyrolysis of plastics [34][35][36][37][38][39][40][41][42][43][44][45][46].…”

This paper presents the results of investigations into the pyrolysis of waste polypropylene in a laboratory fixed-bed batch reactor. The experiments were designed and verified in such a way as to allow the application of the response surface methodology (RSM) in the development of an empirical mathematical model that quantifies the impacts mentioned above. The influence of the mass of the raw material (50, 100, and 150 g) together with the reactor temperature (450, 475, and 500 °C) and the reaction time (45, 50 and 75 min) was examined. It has been shown that the mass of the raw material, i.e., the filling volume of the reactor, has a significant influence on the pyrolysis oil yield. This influence exceeds the influence of reactor temperature and reaction time. This was explained by observing the temperature change inside the reactor at three different spots at the bottom, middle, and top of the reactor. The recorded temperature diagrams show that, with greater masses of feedstock, local overheating occurs in the middle part of the reactor, which leads to the overcracking of volatile products and, from there, to an increased formation of non-condensable gases, i.e., a reduced yield of pyrolytic oil.
