Thermodynamic and multi-step kinetic analysis of slow pyrolysis of natural rubber–silanized cellulose composites with 30–50 phr filler content

Dataset description: original PDF and TIFF/PNG data from original research within the project MEET. Precisely, there are 7 number of Figures, 2 Tables, and zip file with raw data: Fig1a SEM images of CELS (BSE), magnitude 1.00 kx Fig1b SEM images of CELS (BSE), magnitude 6.00 kx Fig2a SEM images of NR-CELS 30, a) fracture surface Fig2b SEM images of NR-CELS 30, b) section Fig3a SEM images of NR-CELS 55, a) fracture surface Fig3b SEM images of NR-CELS 55, b) section Fig4 FTIR spectra of NR, CEL, NR–CEL55, CELS and NR–CELS55 samples in regions a) 4000 – 2500 cm-1 and b) 1800 – 400 cm-1 Tab. 1 Values of Ea (in kJ∙mol-1) calculated according to Friedman method for selected degrees of conversion. Note The arithmetic average of Ea values and the corresponding standard deviations (STD), as well as the maximum values were calculated from the entire data set for α = 0.05–0.95 with a step of 0.01 Tab. 2 Calculated values of the apparent activation energy Ea (kJ mol–1), the apparent pre-exponential factor log A (log s–1), and the exponents n and m of the model f(α) = (1 – α)n αm for the individual steps. TG DTG DTA.zip Raw data DTA TG DTG for NR-CEL 30, NR-CELS 45 and NR-CELS 55 composites, measured at heating rate of 2, 4, 6, 8, 10 and 20 °C/min in the temperature interval 20-600 °C. Kinetic data.zip Calculated values of Ea and A for the Friedman model and values Ea, A and model for the extended Prout-Tompkins model.
