Kinetic studies on combustion of microalgae under different oxygen concentrations

Abstract: In this paper, the combustion behavior of Chlorella vulgaris (a genus of unicellular green microalgae) was investigated in a thermogravimetric analyzer (TGA) from room temperature to 800°°C in O 2 /N 2 atmospheres. The effects of different oxygen concentrations (20, 50, 60, 80 vol.%) in the heating rates 20°C·min -1 on the combustion processes of Chlorella vulgaris had been studied. The results indicated that the combustion processes of Chlorella vulgaris could be divided into three stages. The oxygen concentr… Show more

“…The thermal behavior of SP and the various mixtures containing additives are presented in the TG-DTG curves of Figure 1. Stage I, which occurred at the temperature range of 30-165 o C, relates to the elimination of moisture and light volatile evaporation, as discussed in various studies (Shuping et al, 2010;Xu et al, 2013). Stage II, which began at around 165-500 o C, was the main combustion zone associated with the intense thermal decomposition and burning of organic components.…”
