“…GC‐MS analysis of this fraction identified 1,4:3,6‐di anhydro‐ α ‐ d ‐glucopyranose, palmitic acid methyl ester and hexadecanamide. Other studies have reported the presence of these compounds in A. platensis during biomass processing . The deamination of amino acids as a result of protein hydrolysis yields ammonia that can react with the hydroxyl groups of the fatty acids to produce amides such as hexadecanamide or alcohols formed by the reduction of amino acids after deamination.…”

The various extraction procedures investigated in the present study were effective in deodorizing the algae biomass. The most effective protocol was the removal of odoriferous compounds with ethanol. This particular procedure yielded an algae biomass with an improved sensorial traits. The results of the present study should help with the identification of odoriferous compounds derived from fatty acids, pigments and proteins associated with A. platensis. © 2017 Society of Chemical Industry.

“…For Spirulina , K/(Si + P) = 2.56, which indicates that the reactivity increases along with the conversion . Biomasses with this behavior, depending on the operating conditions, tend to undergo thermal decomposition with higher production of noncondensable gases and/or char; thus, this result indicates that Spirulina can be more suitable for the gasification process due to the high reactivity of its char. The high reactivity is associated with the minerals present in its ashes that are responsible for catalyzing reactions favorable for noncondensable gas formation; however, for the gasification process the temperatures should be higher than that used in this work.…”

“…These compounds are related to the presence of amines, nitriles, pyridine, and indole, which are commonly detected in the pyrolysis products of microalgae; however, the nitrogen content could diminish the bio‐oil quality, due especially to the liberation of NO x pollutants during bio‐oil combustion. Some authors have suggested that the use of a suitable catalyst can convert these nitrogenated compounds into hydrocarbons …”

“…The authors observed that the highest liquid product yield was reached using ZnCl 2 as the catalyst. Chagas et al studied the catalytic pyrolysis of Spirulina microalgae using different catalysts and temperatures. The authors found that the zeolite catalyst (H‐ZSM5 23) could increase the hydrocarbon yield from 0.45% for the uncatalyzed reaction to 6.45% for the catalyzed reaction using a 10:1 catalyst/biomass ratio, a consequent reduction of phenol by 84%.…”

A comparative study of the behavior of Chlamydomonas reinhardtii and Spirulina platensis in solar catalytic pyrolysis

Summary The aim of this study was to investigate the behavior of two distinct microalgae species during solar catalytic pyrolysis and the influence of their chemical composition and the process variables (biomass charge, reaction time, and catalyst percentage) on the product yields and bio‐oil composition. For this purpose, solar catalytic pyrolysis of Spirulina platensis and Chlamydomonas reinhardtii was performed using hydrotalcite‐derived mixed oxides as the catalyst. To gain more insight into the effect of composition on pyrolysis behavior, the biomasses were analyzed using various analytical techniques. The results indicated that a high percentage of catalyst (47.1%) culminated in liquid yields of 42.48% and 21.31% for Chlamydomonas pyrolysis and Spirulina pyrolysis, respectively. Additionally, Spirulina pyrolysis resulted in higher solid yields compared with Chlamydomonas pyrolysis. The results also showed that Spirulina bio‐oil was rich in oxygenated compounds, probably due to its high carbohydrate content, whereas Chlamydomonas bio‐oil was rich in nitrogenated compounds because of its higher protein content. The microalgae composition (lipids, protein, carbohydrates) exerted a large influence on the catalytic pathways and led to differences in yield and product distribution. A high percentage of catalysts preferentially promoted a deoxygenation of the bio‐oil obtained from Spirulina solar pyrolysis compared with that obtained from Chlamydomonas pyrolysis.

“…O uso de microalgas tem se mostrado como uma próspera alternativa, já que tem grandes vantagens em sua produção: seu crescimento é rápido e podem se desenvolver em ambientes hostis. Estudos recentes mostram que a pirólise de microalgas pode ser conveniente na Capítulo 1 -Introdução 3 produção de bio-óleos com melhores características, quando comparados com aqueles originados a partir de material lignocelulósico (HALLENBECK et al, 2016;CHAGAS et al, 2016).…”
