PG - 124874 LID - S0960-8524(21)00213-3 [pii] LID - 10.1016/j.biortech.2021.124874 [doi] AB - This study investigated on the co-pyrolysis of microalgae Chlorella vulgaris and high-density polyethylene (HDPE) waste mixtures which was performed with three types of catalysts, namely limestone (LS), HZSM-5 zeolite, and novel bi-functional LS/HZSM-5/LS. Kissinger-Kai (K-K) model-free method was coupled with Particle Swarm Optimization (PSO) model-fitting method using the thermogravimetric experimental data. A global sensitivity analysis was carried out using Latin Hypercube Sampling and rank transformation to assess the extent of impact of the input kinetic parameters on the output results. Furthermore, a thermodynamic analysis was performed to obtain parameters such as enthalpy change (DeltaH), Gibb's free energy (DeltaG), and entropy change (DeltaS). The activation energy (E(A)) of the microalgae Chlorella vulgaris and HDPE binary mixture were found to be lower upon the addition of catalysts. Among the catalyst used, bi-functional LS/HZSM-5 catalyst exhibited the lowest E(A) (83.59 kJ/mol) and DeltaH (78 kJ/mol) as compared to LS and HZSM-5 catalysts. CI - Copyright (c) 2021 Elsevier Ltd.
