The Acid Hydrolysis of Sugarcane Leaves as a Biofeedstook for Bioethanol Production

Abstract:

The sugarcane is the one of economic agricultural product in Thailand. The sugarcane leaf is a residual waste from post-harvest process. Conversion of the residual waste to a value material is quite a challenge. The aim of this research work is to extract sugar from the sugarcane leaf by the acid hydrolysis reaction. The hydrolysis conditions were varied in terms of sulfuric acid (H₂SO₄) concentration (04%, v/v), reaction time (15180 minutes), amount of sugar cane leaves (50-125g/l) with constant incubation temperature at 122 °C. The identification and quantitation analysis of hydrolysed sample was performed by high performance liquid chromatography (HPLC). The result was shown the best hydrolysis condition was at 1% v/v of H₂SO₄, reaction time 60 min and the sugarcane leaves 100 g / L with ca 17 g/L of xylose, ca 3 g/L of glucose and ca 2 g/L of arabinose. Also, the Scanning Electron Microscopy (SEM) was analysed the morphology of untreated and treated sugarcane leaf which the surface of treated sample showed the broken fibril.
