“…With the presence of OPT and OPF/ OPT ash catalyst in OPT pyrolysis, the mass loss was estimated from 69.70% to 76.77% and 73.63% to 78.87%. Similar observation found in TG and DTG curves for both OPF and OPT pyrolysis process from literature [11,12].…”

“…Stage I of thermal degradation for OPF and OPT pyrolysis started from room temperature to 495K and 500K respectively with a slight reduction of weight fraction of OPF and OPT. This is where the dehydration process takes place to reduce the moisture content and light volatiles of the component [11]. The surface tension tends to cause evaporation to both moisture content and the water bounded of the OPF and OPT biomass surface.…”

“…Pyrolysis process is a thermochemical conversion process which converts lignocellulosic biomass into solid residues, liquid fuels, and noncondensable gases [9,10]. Based on Soon et al [11] and Khan et al [12], it is reported that palm oil wastes such as OPF and OPT are able to achieve the preexponential factor (A) in the range of 1.2×10 13 -1.1×10 17 min −1 and activation energy (E A ) in the range of 160 to 199 kJ mol −1 for pyrolysis process. The chemical composition for OPF in terms of hemicellulose, cellulose, and lignin content are reported to be 31.93%, 42.12%, and 26.05% respectively [13].…”

“…Este crecimiento trae aparejada la producción de grandes cantidades de residuos lignocelulósicos como los racimos de frutos vacíos de la palma aceitera (RFV) y el bagazo de caña de azúcar (BCA), que pueden originar problemas de tipo ambiental y de salud como la propagación de enfermedades en los cultivos [2]. Esta biomasa residual es una carga atractiva como fuente potencial de hidrocarburos y productos químicos con casi cero emisiones de dióxido de carbono [3].…”

“…La pirólisis es un proceso termoquímico donde la biomasa es sometida a calentamiento en ausencia de oxígeno y puede ser convertida en productos gaseosos, líquidos (tar) y sólidos (char), estos productos pueden ser usados como combustibles o precursores para la obtención de productos químicos, las ventajas de la pirólisis respecto a la gasificación y combustión es que tiene menores requerimientos de temperatura, que procede en ausencia de oxígeno y da productos líquidos de alta calidad [3], [4], [5], [6], pese a ello la transformación de la biomasa por pirólisis es altamente dependiente de la cinética de las reacciones de pirólisis, por eso es necesario conocer la cinética de la pirólisis de la biomasa para poder diseñar, modelar y optimizar adecuadamente el reactor, equipo clave en los procesos a escala industrial [7].…”

The kinetics of the catalytic pyrolysis of the empty fruit bunches of the oil palm (EFB) and the sugarcane bagasse (SCB) were investigated, using the non-isothermal thermogravimetric analysis. Two isoconversional methods were applied, the Friedman differential method and the Ozawa-Flynn-Wall integral method. Five catalysts were evaluated: Equilibrium catalyst of FCC (Z2), ZSM-5 in pellet (Z3), zeolite ZSM-5 in spherical pellet (Z4), Zeolite Y powder (Z5) and zeolite ZSM-5 powder (Z6). The activation energy in the pyrolysis of the biomass with and without catalyst was calculated. Biomass with a particle size between 177 to 250 µm was mixed with an equal amount of catalyst (particle size less than 250 µm). In the thermogravimetric analyzer, it was heated from 30 °C to 900 °C under non-isothermal conditions at four heating rates 5, 10, 15 and 20 °C/min respectively, using nitrogen at 60 cm3/min as inertizing gas. Regarding the SCB, it was obtained that the catalyst Z2 had the lowest activation energy of 123.26 kJ/mol (OFW) and 123.91 kJ/mol (Friedman) and the BCA without catalyst 139.57 kJ/ mol (OFW) and 147.88 kJ/mol (Friedman) which indicates that it is the most useful for catalytic pyrolysis of SCB. In the pyrolysis of the EFB, activation energy values of 158.19 kJ / mol (OFW) and 146.56 kJ / mol (Friedman) were obtained without catalyst and that catalyst Z2 had the lowest values of activation energy, 114.48 kJ/mol (OFW) and 102.55 kJ/mol (Friedman), which indicates that it is suitable for catalytic pyrolysis of EFB. The catalyst with the highest activation energy was Z5 for both biomass and both methods (OFW and Friedman). For the SCB, values of 168.47 kJ/mol (OFW) and 168.42 kJ/mol (Friedman) were obtained and for EFB 163.77 kJ / mol (OFW) and 189.27 kJ/mol (Friedman), this indicates that it is not suitable for catalytic pyrolysis of SCB and EFB.
