Catalytic pyrolysis of plastic waste for the production of liquid fuels for engines

Abstract: Catalytic pyrolysis of waste plastics using low cost binder-free pelletized bentonite clay has been investigated to yield pyrolysis oils as drop-in replacements for commercial liquid fuels such as diesel and gasohol 91.

“…These strong degradation peaks corresponded to the decomposition of other plastic films, including PVC, PS, PET, and their mixture [ 31 ]. These values are within the range of those reported in the literature on plastic and plastic mixture [ 31 , 32 , 33 , 52 , 53 ].…”

“…Although the kinetics of pyrolysis packaging plastics (PS/PP, PET/PP, PET/PE film and PP/PE film) was studied thoroughly using different kinetics models [ 31 , 32 , 33 ], only one study was focused on pyrolysis kinetics of MFPWs using model-free methods (as the simplified formal reaction model) [ 11 ], which resulted in big variation in the kinetic parameters at the lower conversion rate (up to 0.7) and unreasonable kinetic parameters at the higher conversion rate. Additionally, it was assumed that by using this model each peak in the DTG analysis curves corresponds to the individual and sequential decomposition of the pseudocomponents, giving the impression that no interactions occur between them [ 34 ].…”

“…[12] The complete weightloss (∼100 %) starts slowly near 415 ºC, reaches a maximum at ∼466 ºC, and finishes at ∼480 ºC. According to Supattra Budsaereechai et al, [13] the catalytic pyrolysis of PP to get liquid products normally takes place at the lower temperature as compared with the pyrolysis without the catalyst. Therefore, in this study, the temperature of the experimental bed reactor was maintained at 450 ºC during the pyrolysis process.…”

“…The evolved gas mainly consisted of CO 2 , CO, CH 4 , and C 2 H 4 which suggests that the main reaction leading to the formation of gas is the de-alkylation of the styrene formed and de-alkylation of methyl-substituted bi-and tricyclic aromatic hydrocarbons. 62,63 The results from published studies on the pyrolysis (<700°C) of plastics were compared with our study (ESI Table 1 †). In our study, a significant reduction in reaction time (<10 min) and temperature (250°C) meant less energy consumption to valorize the plastic waste as compared with other studies.…”
