“…The heating value of bio-oil produced from this conversion process is lower than petroleum diesel and higher heating than other lignocellulosic feedstock, which defines its suitability for fuel oil use [67]. The microwave enhanced pyrolysis (MEP) was further recommended by Zhang, et al [94] as a quick and efficient method for bio-oil production, due to the ability to ameliorate the environment while producing biofuels and chemicals at the same time. Some of the aforementioned technical challenges associated with this conversion process could eradicated, by reducing the oxygen and nitrogen content before its application as a transport fuel [64].…”

An algal feedstock or biomass may contain a very high oil fraction, and thus could be used for the production of advanced biofuels via different conversion processes. Its major advantage apart from its large oil fraction is the ability to convert almost all the energy from the feedstock into different varieties of useful products. In the research to displace fossil fuels, algae feedstock has emerged as a suitable candidate not only because of its renewable and sustainable features but also for its economic credibility based on the potential to match up with the global demand for transportation fuels. Cultivating this feedstock is very easy and could be developed with little or even no supervision, with the aid of wastewater not suitable for human consumption while absorbing CO2 from the atmosphere. The overall potential for algae applications generally shows that this feedstock is still an untapped resource, and it could be of huge commercial benefits to the global economy at large because algae exist in millions compared to terrestrial plants. Algae applications are evident for everyday consumption via foods products, non-foods products, fuel, and energy. Biofuels derived from algae have no impact on the environment and the food supply unlike biofuels produced from crops. However, any cultivation method employed could control the operating cost and the technicalities involved, which will also influence the production rate and strain. The scope of this paper is to review the current status of algae as a potential feedstock with diverse benefit for the resolution of the global energy demand, and environmental pollution control of GHG.

“…The green alga C. reinhardtii is usually cultured in laboratories at a PPFD of 100 µmol m -2 s -1 or less (Roach et al 2017, Xing et al 2017, Andrade et al 2018, Lin et al 2018, Yang et al 2018, and earlier growth tests suggest that wild-type C. reinhardtii does not grow rapidly in strong, oversaturating light (Schierenbeck et al 2015, Lin et al 2018. However, spontaneous mutations improving the ability to withstand high light occur frequently (Förster et al 2005).…”

The volumetric productivity of the highlight tolerant strain hit2 of Chlamydomonas reinhardtii was found to be higher than that of the parental strain CC124 during continuous growth at PPFD from 200 to 1,500 µmol m-2 s-1. At PPFD of 1,250 µmol m-2 s-1 , hit2 produced 2.53 ± 0.18 and CC124 produced 2.05 ± 0.12 g(biomass) dm-3 d-1. The rate constant of photoinhibition of hit2 was less than half of that of CC124, suggesting that hit2 produces more biomass than CC124 because hit2 does not need to allocate as much resources for PSII repair as CC124. Growth in high light triggered similar loss of chlorophyll, increase in the carotenoid-to-chlorophyll ratio, and decrease in PSI fluorescence in both strains. Thermoluminescence B band was shifted toward the Q band in hit2, suggesting that low redox potential of the QB/QBpair contributes to the photoinhibition tolerance of hit2.

“…The comparison between the results of test 13 (without catalyst) and test 14 (highest catalyst percentage and with the other variables at the same values as those test 13), shows that the use of the catalyst led to an increase in the oxygenated compounds for the solar pyrolysis performed with Chlamydomonas . This increase can be attributed to the fact most of oxygenated compound content in Chlamydomonas comes from catalytically facilitated degradation of the lipid fraction lipid, which is the compound of greatest thermal stability in microalgae . Regarding the hydrocarbon presence, the bio‐oil produced from the pyrolysis of Chlamydomonas reinhardtii in test 14 presented a hydrocarbon content close to that obtained in test 13 (without catalyst); however, test 15, which was performed with an intermediate percentage of catalyst, showed a significant increase in the hydrocarbon content (over 40%).…”

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.
