A Comparison of Bioethanol and Biochar Production from Various Algal Biomass Samples and Sweet Sorghum Energy Crop

Year 2018, Volume: 1 Issue: 1, 43 - 50, 01.01.2018

Abstract



In this study, bioethanol and
biochar production from various algal biomass samples (
Chlorella minutissima,
Chlorella vulgaris, Nannochloropsis oculata
microalgae and Laminaria digitata, Codium fragile, Ulva
lactuca
macroalgae) and an energy
crop sample (sweet sorghum bagasse
) were investigated. In bioethanol production, acid
pre-treatments were performed with 2 N H
2SO4 solution at
the temperature of 100°C, and pre-treatment time of 60 minutes. Fermentation
was carried out in erlenmeyer flasks which were placed in a shaking incubator
set to the 150 rpm at the temperature of 30°C for 48 hours. The highest
bioethanol yield was obtained as 44% by utilizing sweet sorghum.
  Biochar
production was carried out at a heating rate of 20°C/min, 250 ml/min nitrogen
flow rate and temperature of 400°C in a carbonization retort. The characterization
of biomass samples were performed, and all biofuel yields were compared.
Although sweet sorghum as an energy crop has higher bioethanol
production potential than micro and macroalgae sources, especially macroalgae can
be a remarkable solution of waste utilization as a new generation feedstock of biosorbent
and biochar production.
