Jawad %V 289 %T Catalytic pyrolysis of Chlorella vulgaris: Kinetic and thermodynamic analysis %X In the present study, catalytic pyrolysis of Chlorella vulgaris biomass was conducted to analyse the kinetic and thermodynamic performances through thermogravimetric approach. HZSM-5 zeolite, limestone (LS), bifunctional HZSM-5/LS were used as catalysts and the experiments were heated from 50 to 900 °C at heating rates of 10�100 °C/min. Iso-conversional model-free methods such as Flynn-Wall-Ozawa (FWO), Kissinger-Akahira-Sunose (KAS), Starink's, and Vyazovkin (V) were employed to evaluate the kinetic parameters meanwhile the thermodynamic parameters were determined by using FWO and KAS methods. The calculated EA values of non-catalytic and catalytic pyrolysis of HZSM-5 zeolite, LS, and bifunctional HZSM-5/LS were determined to be in the range of 156.16�158.10 kJ/mol, 145.26�147.84 kJ/mol, 138.81�142.06 kJ/mol, and 133.26 kJ/mol respectively. The results have shown that catalytic pyrolysis with the presence of bifunctional HZSM-5/LS resulted to a lower average EA and �H compared to HZSM-5, and LS which indicated less energy requirement in the process. © 2019 Elsevier Ltd %K Kinetics; Lime; Polymer blends; Pyrolysis; Thermoanalysis; Thermodynamic properties; Zeolites, Catalytic pyrolysis; Chlorella vulgaris; Energy requirements; Kinetic analysis; Thermo dynamic analysis; Thermo-gravimetric; Thermodynamic parameter; Thermodynamic performance, Thermogravimetric analysis, limestone; zeolite, biomass burning; catalysis; green alga; heating; limestone; pyrolysis; reaction kinetics; thermodynamics; thermogravimetry; zeolite, Article; biomass; catalysis; catalyst; Chlorella vulgaris; controlled study; heating; nonhuman; priority journal; pyrolysis; thermodynamics; thermogravimetry; biocatalysis; Chlorella vulgaris; heat; kinetics; metabolism; pyrolysis, Chlorella vulgaris, Biocatalysis; Biomass; Chlorella vulgaris; Hot Temperature; Kinetics; Pyrolysis; Thermodynamics; Thermogravimetry %R 10.1016/j.biortech.2019.121689 %D 2019 %L scholars11290 %J Bioresource Technology %O cited By 58
