“…The activation energy of the thermal degradation of polypropylene, oil shale and a 1:3 mixture of the two is found to be 250 kJ/kg, 63 kJ/kg, and 242 kJ/ kg respectively investigated from thermogravimetric experiments in an inert atmosphere. The degradation process is affected by heating rate and the process is catalysed by the presence of PP …”

The thermo‐degradative behaviour of non‐woven plastics was studied in order to analyze their thermal stability and subsequent recycling method. Non‐isothermal thermogravimetric experiments using wide range of heating rates of 10, 20, 40, 60, 80,100 °Cmin−1 have been performed from ambient to 900 °C in a thermo‐balance with the objective of determining the kinetic parameters. Four model free kinetic approaches such as Friedman method, Coats‐Redfern (modified) method, Flynn–Wall–Ozawa (FWO) method and Kissinger method have been used to determine kinetic parameters for the two stage degradation of the non‐woven plastic sample including the thermal degradation of synthetic plastics in the first step followed by the subsequent degradation of inorganic fillers in the second step. The activation energy obtained for first stage degradation is found significantly lower (106‐112 kJ/mol) compared to the second stage degradation (191‐202 kJ/mol). This result would help design a process for the valorisation of synthetic polymer and segregation of the filler materials in the plastic sample to be reused further.

“…These materials are rich in hydrogen in comparison with coal (Liu et al, 1994;Horvat and Flora, 1999;Uddin et al, 1999;Uzumkesici et al, 1999;Mastral et al, 2000;Sakurovs, 2003) and oil shale (Ballice et al, 1998;Gersten et al, 1999Gersten et al, , 2000Ballice, 2001;Tiikma et al, 2004). Oil shale, on the other hand, is considered to be the substitute for oil as a natural source of energy.…”

“…It has been suggested that the addition of plastic to the oil shale during conversion may result in enhanced oil shale conversion and oil production compared with the yields obtained when oil shale alone is treated (Ballice et al, 1998;Gersten et al, 1999;Tiikma et al, 2004). The pyrolysis of oil shale mixed with plastics can on the one hand improve the effectiveness of oil shale processing and on the other hand provide a solution for the waste problem.…”

“…This will help in generating more power per unit of fuel consumed and will also reduce the amount of CO 2 per unit power generated (Smith and Nalbandian, 2000;Vanloon and Duffy, 1999) and thus the greenhouse effect. These plastics can, in fact, be pyrolysed to generate raw materials for chemicals and petrochemical industries (Gersten et al, 1999). The co-pyrolysis/co-cracking of these plastics and coal may lead to the formation of some interesting products by thermal degradation and reformulation reactions.…”

The kinetics of co-combustion/co-cracking of Topa coal with polystyrene, poly(vinyl chloride), and bakelite have been studied by theromogravimetric analysis at a linear heating rate of 20 ı C/min in a stream of air for combustion and in nitrogen for cracking with a flow rate of 20 cm 3 /min up to the temperature of 900 ı C under non-isothermal conditions. The order of reaction and overall activation energy of the reactions have been calculated. These studies may help in synergistic production of value-added organic compounds and spatiality chemicals from coal and plastics.
