“…Thus, virtually all of the bio-oil produced in this work met this requirement. When compared with the water content of bio-oil produced from the same biomass feedstock (cassava rhizome), the water content of the bio-oil produced with the moving-bed granular filter (24.3-31.3 wt.%) was somewhat higher than that of the bio-oil produced with the glass wool filter (18.0 wt.%) (Pattiya and Suttibak, 2012b). This could be owing to the lower thermal cracking of the pyrolysis vapour when passing the glass wool in comparison to the silica sand.…”

ResumenIntroducción− La pirólisis de residuos agroindustriales es una alternativa para generar combustibles líquidos de segunda generación. Objetivo− Determinar la cinética de la pirólisis de residuos industriales de yuca y de formación de productos. Metodología− Se estudió la pirólisis de residuos provenientes de la industria del almidón de yuca utilizando termogravimetría acoplada a espectrometría de masas. Los datos termogravimétricos fueron ajustados al modelo cinético de distribución de energías de activación, siendo necesario el uso de solo un pseudocomponente. Resultados− La pirólisis de las muestras calentadas a velocidades inferiores a 30 K/min mostró valores de los paráme-tros cinéticos diferentes a los de la pirólisis de las muestras calentadas a velocidades superiores a 50 K/min, lo cual sugiere un cambio de mecanismo con la velocidad de calentamiento. Los valores obtenidos de los parámetros cinéticos de la pirólisis de los residuos estudiados se encuentran en el rango reportado por la literatura para otros tipos de biomasa. Se identificaron 23 relaciones m/z en los gases desprendidos de la muestra con suficiente relación señal/ruido. Las señales de espectrometría de masas seleccionadas fueron ajustadas con el modelo DAEM utilizando los parámetros cinéticos obtenidos con los datos termogravimétricos. Conclusiones− Se lograron buenos resultados de ajuste con el modelo DAEM de un solo pseudocomponente para la mayoría de las relaciones m/z. La falta de ajuste para algunas relaciones m/z se puede atribuir a reacciones secundarias en fase gaseosa. Palabras clave− Análisis termogravimétrico; cinética; espectrometría de masas; pirólisis; biomasa Abstract Introduction− The pyrolysis of agro-industrial waste is an alternative to produce second generation liquid fuels. Objective−Determine the kinetics in the pyrolysis process of cassava industrial waste as well as of evolved product formation. Methodology− Pyrolysis of waste from cassava starch processing was studied via thermogravimetric analysis coupled to mass spectrometry. Thermogravimetric data were adjusted to the distributed activation energy model with one pseudocomponent. Results− Pyrolysis of samples heated at ramps below 30 K/min showed kinetics parameters with different values from the ones obtained for the samples heated at ramps above 50 K/min. This suggests a change in the pyrolysis reaction mechanism linked to heating rate. The kinetics parameters obtained in this work are in agreement with values reported for other biomass in literature. From the evolved gases, 23 m/z signals were identified with enough signal/noise ratio. Mass spectrometry signals were also adjusted with the distributed activation energy model using the kinetics parameters obtained from thermogravimetric data. Conclusions− Satisfactory results were achieved with the DAEM model with one pseudocomponent for most of m/z ratio. The lack of adjustment in some m/z ratio can be attributed to secondary reactions in the gas phase. Keywords− Thermogravimetric analysis; kinetics; mass s...

AbstractThe upgrading of pyrolysis oil to bio-fuel was investigated using sub-and supercritical water at 410 and 450 o C, with a high mass ratio of water to pyrolysis oil to ascertain the maximum yields that could be achieved. The results indicate that conversions increased with increasing pyrolysis oil to water mass ratio at high water ratio under supercritical water conditions at 410 o C, gave the highest products conversion of ~91 wt. %, with 28 wt. % heavy oil recovered, ~23 wt. % gas yield, 27 wt. % water generated and approximately 13-14 wt. % of light oil produced. Similar product conversion was obtained using biomass as a feedstock with slightly higher water mass ratio added into the reactor (R1:15), and slightly lower heavy oil yield was recovered (21 wt. %). Gas generation was observed to % of water generated. The oxygen contents of the heavy oil recovered were ~15-16 % (for 410 and 450 o C), with H/C atomic ratios of 1.1. Similar overall conversions were achieved using tetralin with much lower solvent to oil ratios were needed and the liquid products had a slightly lower oxygen 2 content (14 %). The estimated hydrogen from water was estimated as ca. 0.3 % at 410 and 450 o C in high conversions of pyrolysis oil experiments, and experiments with tetralin/1-methyl naphthalene provide evidence that a small amount of hydrogen was sufficient to achieve high product conversion, giving an increase of H element content from 7.0 % to 7.3 %.
