Kinetic study of the thermal decomposition of polypropylene, oil shale, and their mixture

New piezoelectric composites based on isotactic polypropylene filled with silicate

“…Two next extrema: exothermic peak at 380 °C and endothermic one at 484 °C are directly connected with sample decomposition and emission of degradation products. The detailed mechanism and kinetics of thermal degradation of the i-PP had been previously discussed in the literature [14][15][16][17][18]. The volatile products of PP decomposition in inert atmosphere are alkanes, alkenes, dienes and even small amount of aromatic compounds.…”

Study of the Kinetics and Mechanisms of Thermal Decomposition of Moroccan Tarfaya Oil Shale and Its Kerogen

“…The lateral shift to higher temperatures for the maximum region of mass loss has also been observed by other workers using TGA to investigate the pyrolysis of oil shales. For example, Gersten et al [25] showed a lateral shift in the maximum rate of weight loss of about 38 °C as the heating rate was increased from 5 to 50 K/min for Israel oil shale. Kök [5] and Jaber and Probert [7,19] also showed a lateral shift in the maximum rate of mass loss for the TGA of oilshale samples.…”

Non-isothermal degradation kinetics of filled with rise husk ash polypropene composites

“…In order to recycle plastic waste to obtain energy or low molecular hydrocarbons, other additives, for example solids, contained Lewis and Brǿnsted acid centers, are used to decrease the thermal stability of the composites [8][9][10]. Therefore, comprehension of the kinetics of its thermal degradation is of great interest for both theory and practice.…”

“…Because they are not easily biologically degradable and because of their weight-to-volume ratios which creates problems of disposal, the plastics are not appropriate candidates for landfilling [8,9,12,17]. Nowadays, incineration is the more widely used way to eliminate solid residues and it is also used for generation of electric and calorific energy at the same time.…”
