“…The medium is locally available and cheap in cost. Though cassava peel which is an abundant agro waste in the processing of cassava to various products has been used in several biotechnological processes to produce enzymes (Sani et al, 1992;Lateef et al, 2008;, bio-oil (Ki et al, 2013), carriers for biofertilizer production (Ogbo and Odo, 2011), bio-ethanol (Sivamani and Baskar, 2015), and animal feeds (Olafadehan et al, 2011;Ruqayyah et al, 2014), there is limited utilization/evaluation of the waste for the production of citric acid (Ogunka-Nnoka et al, 2011).…”

“…Varios estudios de la pirólisis de residuos industriales de yuca se han publicado, incluyendo el uso de reactores tubulares de lecho fijo [9], [17], reactores de lecho fluidizado [18], [19], reactores de caída libre [20] y balanza termogravimétrica [7], [21]; sin embargo, se cuenta con muy poca información que analice los gases producidos en la pirolisis de los residuos industriales de yuca.…”

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...

The use of fossil fuels produces carbon dioxide (CO2). Carbon dioxide is one of the greenhouse gasses that contributes to global climate change. Due to this issue, there is increasing the requirement for the use of renewable materials and development of the additional sustainable process. Agricultural waste that has the property of fast growth, is an alternative renewable energy. In this work the slow pyrolysis of selected agricultural wastes mixture (cassava peel-rice straw, rice straw-rice husk, and cassava peel-rice husk) were studied to determine thermal degradation behavior of the biomass. The process was conducted in a fixed bed reactor at temperatures 325 °C, at 10 °C/min heating rate and at 10 min holding time. Results revealed that the moisture content of agricultural wastes were 4.40 % (cassava peel-rice husk), 5.48 % (rice straw-rice husk) and 8.12 % (cassava peelrice straw). The devolatilization process of the biomass was taken place in the temperature range from 189 o C to 325 o C. The volatile matter of each sample was 61.5% for cassava peel-rice husk, 58.5 % for rice straw-rice husk and 52.5 % for cassava peel-rice straw.
