Production of Third Generation Bioethanol via Hydrolysis of Macroalgae (Seaweed) \nUsing Heterogeneous Catalyst

Year: 2013

Type: book

Abstract: The efficacy of red macroalgae Eucheuma cottonii (EC) as feedstock for third-generation bioethanol \nproduction was evaluated. Dowex (TM) Dr-G8 was explored as a potential solid catalyst to hydrolyzed \ncarbohydrates from EC or macroalgae extract (ME) and pretreatment of macroalgae cellulosic residue \n(MCR), to fermentable sugars prior to fermentation process. The highest total sugars were produced at \n98.7 g/L when 16% of the ME was treated under the optimum conditions of solid acid hydrolysis (8% \n(w/v) Dowex (TM) Dr-G8. 120 "C, 1 h) and 2% pretreated MCR (P-MCR) treated by enzymatic hydrolysis \n(pH 4.8. 50 ®C, 30 h). Atwo-stream process resulted in 11.6 g/L of bioethanol from the fermentation of \nME hydrolysates and 11.7 g/L from prehydrolysis and simultaneous saccharification and fermentation of \nP-MCR. The fixed price of bioethanol obtained from the EC is competitive with that obtained from other \nfeedstocks.
