Influence of Solvents Used for Cassava Rhizome Pretreatment on Fast Pyrolysis Products

Main Article Content

อดิศักดิ์ ปัตติยะ


Three solvents including water, hexane and acetone were used to pretreat cassava rhizome. The pretreated biomass samples had lower extractives content compared to the non-extracted one. The pretreated samples together with the original biomass were fast pyrolysed in a fluidised bed reactor producing bio-oil, char and gas. The results showed that after extraction with water, hexane and acetone, the yields of total bio-oil, heavy bio-oil and gas increased at the expense of light bio-oil and char yields. A maximum total bio-oil yield of 54 wt% was achieved when using water as solvent. Based on the property analyses, all solvents hardly affect the pH, solids content, ash content and density of bio-oils. However, hexane and acetone could increase the bio-oil heating value. In addition, the flash point, fire point, hydrogen and oxygen contents were increased by the solvent extraction, whereas the carbon content of bio-oil reduced except when using acetone.
