Lignocellulosic biomass could be used as a feedstock for second generation biofuel production where it is subjected to hydrolysis into sugar after which it can be converted into bioethanol through fermentation process. The advantages of using second generation biofue1s such as bioethanol includes efficient waste management and environmentally friendly fuel supply. Banana pseudo-stem a residue from the banana plantation is also a potential raw material for bioethanol production. In this study the matured banana pseudo-stem is used as the feedstock for bioethanol production. The objective of this research is to study the effects of different chemical treatments on the sugar yield from banana pseudo-stem. Pre-treatment of the banana fibre were carried out in two conditions. For the first set banana fibre was stirred with sulphuric acid of concentrations 0.5 M 0.75 M and 1.0 M at 75C for 90 minutes. While in the second set of chemical treatments 1 of 0.1 M of hydrogen peroxide was added to the sulphuric acid solution. The pre-treated fibre then was analysed with Fourier Transform Infrared FTIR for chemical compositional analysis while the hydrolysate was analysed for sugar contents with a total soluble solid TTS pocket refractometer. Then dried pre-treated fibre was subjected to acid hydrolysis using 0.75 M 1.25 M and 1.75 M of sulphuric acid at 90C for 1 hour. The highest sugar yielded was 9.4 which was obtained from fibre treated with 1.0 M H2S04. A 9.8 yield was obtained from fibre treated with 0.75 M H2S04added with 0.1 M H202. For acid hydrolysis treatment both types of pre-treated fibre hydrolysed most with 1.75 M H2S04. With the results obtained it can be concluded that banana pseudo-stem can be one of the raw material for bio-ethanol production. Also by utilizing this material also can add value to the banana plantation waste.

Abstract

Lignocellulosic biomass could be used as a feedstock for second generation biofuel production where it is subjected to hydrolysis into sugar after which it can be converted into bioethanol through fermentation process. The advantages of using second generation biofue1s such as bioethanol includes efficient waste management and environmentally friendly fuel supply. Banana pseudo-stem a residue from the banana plantation is also a potential raw material for bioethanol production. In this study the matured banana pseudo-stem is used as the feedstock for bioethanol production. The objective of this research is to study the effects of different chemical treatments on the sugar yield from banana pseudo-stem. Pre-treatment of the banana fibre were carried out in two conditions. For the first set banana fibre was stirred with sulphuric acid of concentrations 0.5 M 0.75 M and 1.0 M at 75C for 90 minutes. While in the second set of chemical treatments 1 of 0.1 M of hydrogen peroxide was added to the sulphuric acid solution. The pre-treated fibre then was analysed with Fourier Transform Infrared FTIR for chemical compositional analysis while the hydrolysate was analysed for sugar contents with a total soluble solid TTS pocket refractometer. Then dried pre-treated fibre was subjected to acid hydrolysis using 0.75 M 1.25 M and 1.75 M of sulphuric acid at 90C for 1 hour. The highest sugar yielded was 9.4 which was obtained from fibre treated with 1.0 M H2S04. A 9.8 yield was obtained from fibre treated with 0.75 M H2S04added with 0.1 M H202. For acid hydrolysis treatment both types of pre-treated fibre hydrolysed most with 1.75 M H2S04. With the results obtained it can be concluded that banana pseudo-stem can be one of the raw material for bio-ethanol production. Also by utilizing this material also can add value to the banana plantation waste.
