“…The application of degradation catalysts for pyrolysis processes, were initially carried out with clays and amorphous silica alumina, gradually with time evolved emphasize on zeolites which are chiefly acidic catalysts e.g. zeolite Y, ZSM-5 and Mordenite [62,63,64,65,66,67,68,69,70,71,72,73,74,75,76,77]. Mainly acidic catalysts promotes production of light hydrocarbons (C 5 -C 12 ) in the range of gasoline, while pyrolysis using non-acidic catalysts produces compounds (C 12 -C 22 ) in the range of kerosene and diesel [78,79,80,81,82].…”

Nowadays, increasing population, widespread urbanization, rise in living standards together with versatile use of polymers have caused non-biodegradable polymeric wastes affecting the environment a chronic global problem, simultaneously, the existing high energy demand in our society is a matter of great concern. Hence forth, this review article provides an insight into the technological approach of pyrolysis emphasizing catalytic pyrolysis for conversion of polymeric wastes into energy products and presents an alternative waste management technique which is a leap towards developing sustainable environment. Pyrolysis of waste non-biodegradable polymer materials involves controlled thermal decomposition in the absence of oxygen, cracking their macromolecules into lower molecular weight ones, resulting into the formation of a wide range of products from hydrogen, hydrocarbons to coke. Nanocatalyzed pyrolysis is a recommended solution to the low thermal conductivity of polymers, promoting faster reactions in breaking the CC bonds at lower temperatures, denoting less energy consumption and enabling enhancement in the process selectivity, whereby higher value added products are generated with increased yield. Nanotechnology plays an indispensable role in academic research as well as in industrial applications. Existing reviews illustrate that one of the oldest application field of nanotechnology is in the arena of nanocatalysis. Nanocatalysis closes the gap between homo and heterogeneous catalyses while combines their advantageous characteristics and positive aspects, reducing the respective drawbacks. During the current nanohype, nanostructured catalysts are esteemed materials and their exploration provide promising solutions for challenges from the perspective of cost and factors influencing catalytic activity, due to their featured high surface area to volume ratio which render enhanced properties with respect to the bulk catalyst.

“…Effect of temperature on pyrolysis yields (wt%). (López et al, 2011a) In an other research, Chinese researchers (Lin, 2009) found that with a fluidized-bed reactor system, excellent heat and mass transfer, and much less proneness to clogging with molten polymer could be reached at 390 °C. The technology used gave a nearly constant temperature throughout the reactor.…”

Recycling technologies gained increased importance in the past decades, since environmental issues and the questions of depleting natural resources. Wastes may be considered as resources of valuable secondary raw materials. This literature review aims at compiling the information available on questions arising from the differences between the chemical composition of traditional fuels and chemical industrial raw materials, together with the analytical chemical methods being able to answer these questions. Issues of technical optimisation, the composition of end-products, and their dependence on the technical parameters of pyrolysis will also be discussed.
