“…In all these studies, thermogravimetric analysis (TGA) is the most commonly applied technique and through it, the continuous mass loss characteristics of samples could be obtained to clarify their pyrolysis or gasification behavior. Due to the limited sample mass on TGA, studies on pyrolysis behavior or its impact factors were also conducted on fixed bed reactor with more mass of samples [3,[12][13][14][15][16][17][18][19][20][21]. However, the investigation on the latter normally was based on batch experiments and focused on products characteristics and their impact factors, while could not be compared directly to that on TGA because of lack of real-time data on the same base.…”

In recent years, algal bioethanol production comes into prominence as a trend towards sustainable development. Due to being sustainable energy source and environmental friendly, bioethanol production from algae is becoming increasingly popular all over the world. However, yield of bioethanol production from algae is lower than first generation feedstock's currently, and needs to be improved. In order to increase bioethanol yield, pre-treatments should be performed as cell disruption process on algal biomass. For this reason, researchers investigate the most appropriate pre-treatment method and its parameters for high yield bioethanol production from algae. In this study, cultivated Chlorella minutissima was utilized for bioethanol production. Effects of pre-treatment method (dilute acid and alkaline), chemical concentration, pre-treatment temperature and pre-treatment time on bioethanol yield were investigated. It was found that, the highest bioethanol yield was obtained as 18.52% with acid pre-treatment at pre-treatment temperature of 100 °C and pre-treatment time of 60 minutes.

“…Hemicellulose and cellulose of the raw material, the main components of biomass start to decompose at 240.3 • C. The temperature at which the maximum decomposition occurs is determined as 335.8 • C. All of the components (hemicellulose, cellulose and lignin) of the raw material decompose very rapidly at this temperature reaching a maximum weight loss. The maximum weight loss (69.2%) of the raw material was occurred between 240.3 and 351 • C. At 351 • C, rate of decomposition gradually decreases and gets a minimum approximately at 535 • C. After 535 • C, difference in weight loss gets smaller and becomes almost zero at 800 • C [43][44][45]. The high amount of substances left behind (25%) after 850 • C is related to the content of fixed carbon and inorganic materials (ash) in raw material which were not decomposed at this temperature.…”
