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...

“…Some studies on the utilization of cassava residues for the bio-oil production by pyrolysis process have been reported (Pattiya, 2011;Pattiya et al, 2012). Pattiya and co-workers used rhizome and stalk of cassava as feedstocks to obtain bio-oil by fast pyrolysis process in two reactors: fluidized bed reactor (Pattiya, 2011) and free fall reactor .…”

“…Weerachanchai et al (2011) carried out slow pyrolysis from cassava pulp residues and palm kernel cake and their formed products, included solids, liquids and gases. Pattiya et al (2012) used the fast pyrolysis of agricultural residues, i.e. cassava plantations, in free fall reactor of laboratory scale to investigate effects of this biomass and the pyrolysis conditions, such as reactor temperatures, condensation, nitrogen flow rate and execution duration in the distribution from pyrolysis products.…”

“…Pyrolysis is considered an industrially realized process for biomass conversion (Truman et al, 2004;IITA, 2005). This process can be divided into three subclasses, that is slow, flash and fast pyrolysis (Karan et al, 2011;Pattiya et al, 2012). According Zabaniotou and Ioannidou (2008) the slow pyrolysis occurs under a low heating rate, which obtain more charcoal yield, while the flash pyrolysis is a rapid heating rate process occurring at moderate temperatures (400 to 600°C), obtaining maximized volatile products at short residence time and occurs at high temperature and longer residence times, increasing the biomass conversion and returning more gas product.…”

Bioenergy production from biomass and agricultural wastes has gained significant interest due to rising fossil fuel prices and their decrease in air pollutant emissions. This review paper evaluates the state-of-art for the several applications from cassava harvest residues and their use in bioenergy industry, using different thermochemical and biochemical processes. Regarding the great available literature for this biomass, several pretreatment techniques, including mechanical, chemical, biological, thermal, ultrasonic and wet explosion were observed. The use of cassava harvest residues for the biochemical pretreatments, for example, hydrolysis, fermentation and thermochemical processes, such as direct combustion, gasification, pyrolysis, fast pyrolysis and oxy-fuel combustion was also discussed. Therefore, studies are necessary in order to understand that the use of cassava residues in thermal processes can increase the viability of this feedstock for biofuels production and/or in power co-firing units. After extensive study, it was observed that informations are still lacking about the use of cassava harvest residues in other conversion processes, thus, new studies to discover more on the use of this biomass, in order to extend their application in the bioenergy market is encouraged.

Microbial, vegetal or animal organic matter, which has potential to be transformed into energy, is considered biomass. Among the various alternative energy sources, biomass is the only one with the possibility of generating a class of substances of interest for fine chemistry (ketones, aldehydes, alcohols, phenols, etc.). From biomass, it is possible to produce bio-oil using pyrolysis, a thermodegradation process. The quality of the bio-oil depends on the process conditions (pyrolysis temperature, heating temperature, etc.) and biomass used. In this paper, the pyrolysis (using a fixed bed reactor) of three biomasses (coconut fiber, coffee grounds and sugar cane straw) is studied. The results indicated that the bio-oil yields for all biomass were similar, approximately 37%. The chemical profile obtained by gas chromatography coupled with mass spectrometry (GC/qMS) showed high amounts of fatty acids in the coffee grounds bio-oil and aliphatic and aromatic hydrocarbons in coconut fiber bio-oil, whereas guaiacols were the predominant components of the sugar cane straw bio-oil.
