A step-by-step model for pyrolysis kinetics of polyethylene in an autoclave under non-linear increase of temperature

The Pyrolysis Characteristics and Kinetics of the Marine MacroalgaeEnteromorpha proliferaUsing a Thermogravimetric Analyzer

“…Biomass pyrolysis is commonly regarded as technically and economically feasible. The investigation of biomass pyrolysis kinetics can obtain the pyrolysis parameters, which is significant for evaluating the reaction mechanism and the influence factors (Antal and Friedman, 1980;Arpa et al, 2010;Babu and Chaurasia, 2004;Hujuri et al, 2008;Johannes et al, 2004;Ngo et al, 2010;Órfã and Figueiredo, 2001;Parikh et al, 2007;Stolarek and Ledakowicz, 2005;Wang et al, 2006;Zhou et al, 2010).…”

Modelling of the pyrolysis of high density polyethylene

“…Pyrolysis process is described by means of one or two global reactions. Most authors [3][4][5][6] obtain the kinetic parameters and the order of the reactions from TGA data, under isothermal and/or non-isothermal conditions. The parameters calculated differ significantly maybe due to experimental differences, presence of aditives, etc., although the main reason for these discrepancies is the description of a complex phenomenon using a global kinetic scheme [7].…”

A Comparative Analysis of the Kinetic Experiments in Polyethylene Pyrolysis

“…The techniques adapted by researchers for estimating the pyrolysis kinetics could be categorized under two distinct types: open and closed reactors [9]. Details of the experimental techniques and process conditions employed by various researchers for LDPE pyrolysis studies are summarized in Table 2.…”

“…The physicochemical behavior of plastics during thermal degradation plays a vital role in reactor design and scale-up of industrially viable recycling processes. While a few experimental studies have focused on investigating the effects of various process conditions, including reaction temperature and time on the product yield [3][4][5][6][7], others have focused on understanding the kinetics of the thermal degradation process [8][9][10][11][12][13][14][15][16][17][18][19], the influence of process parameters on product distribution [20], the effect of waste properties and input operational parameters on chemistry and product composition [21], and the effect of postuse fluidized catalytic cracking catalysts [22]. It has been observed that the kinetic parameters (preexponential constant, reaction order and activation energy) reported in literature for the pyrolysis of LDPE differing significantly.…”
