“…The locations of adsorption peaks for the two microalgae are identical, suggesting the types of functionalities of the two microalgae does not make too much differences. The prominent adsorption peaks at 1800-1500 cm À1 suggest the presence of proteins (Phukan et al, 2011), consistent with the relative high content of proteins for the two microalgae. The carbonyl stretching C@O appeared at 1647 cm À1 is related to amide-I bonds while the CAN stretching and NAH bending at 1533 cm À1 are ascribed to amide-II bonds.…”

h i g h l i g h t sCombustion of low-lipid microalgae C. pyrenoidosa and S. platensis were studied. Chemical functional groups present in two microalgae were investigated via FTIR. Apparent activation energies for combustion of the two microalgae were calculated. C. pyrenoidosa has a higher reactivity compared to S. platensis during combustion. a r t i c l e i n f o t r a c tThermogravimetric analysis and differential thermal analysis were employed to investigate combustion characteristics of two low-lipid microalgae, Chlorella pyrenoidosa (CP) and Spirulina platensis (SP) and isoconversional Starink approach was used to calculate the kinetic parameters in the present study. The results showed that three stages of mass loss, including dehydration, devolatilization and char oxidation, were observed during combustion of both of two low-lipid microalgae. The whole weight loss of combustion of two microalgae was both shifted to higher temperature zones with increased heating rates from 10 to 40 K/min. In the 0.1-0.9 conversion range, the apparent activation energy of CP increased first from 51.96 to 79.53 kJ/mol, then decreased to 55.59 kJ/mol. Finally, it slightly increased to 67.27 kJ/mol. In the case of SP, the apparent activation energy gradually increased from 68.51 to 91.06 kJ/mol.

“…A model of microalgae oil was developed, containing 9 fatty acids and 9 triglycerides. Protein content was of 40% (Kay, 1991;Phukan, Chutia, Konwar & Kataki, 2011). For carbohydrates, the literature reports about 25%, including carbohydrates such as cellulose and hemicellulose (Ververis et al, 2007).…”

“…and Chlorella sp. (Phukan et al, 2011;Wang et al, 2013). Microalgae harvesting remain a major hurdle to industrial scale processing, and it was estimated to account for 20-30% of the total biomass production cost (Molina Grima et al, 2003).…”
