“…Azizi et al stated that proteins produce large amounts of nitrogen heterocycles, pyrroles, and indoles; lipids led to fatty acid formation, and the carbohydrates result in ketones, phenols, and other oxygenated compounds. Studies also revealed that a high lipid content produces a bio‐oil with a higher amount of fatty acids and a lower amount of nitrogenated compounds . The pyrolysis reactions result in crude oil with undesirable characteristics, including a low higher heating value (HHV), a high viscosity, and an instability that limit its direct use as a transportation fuel in current systems .…”

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.

“…Além disso, a utilização do catalisador na configuração ex situ melhorou a seletividade para a formação de hidrocarbonetos alifáticos e aromáticos para as temperaturas estudadas, sendo mais pronunciado na temperatura de 550ºC e menos pronunciado na temperatura de 750ºC. Segundo Na et al (2015) a formação de hidrocarbonetos de cadeia longa bem como de ácidos e ésteres está associada à degradação de lipídeos constituintes do bio-óleo. Wang et al (2014b) que também estudaram a pirólise catalítica ex situ, observaram que os hidrocarbonetos aromáticos produzidos foram enriquecidos e se tornaram os compostos mais abundantes, com a presença do catalisador.…”
