In this study, the effect of extractive content on fuel properties of selected woody and non-woody biomass samples has been evaluated. The results show significant variation in the amount of extractives (15–70%) present in different biomass samples. There is significant decrease in ash content, fixed carbon content and calorific value in extractive-free samples. The elemental carbon reduces after extraction in woody biomass. There is no specific trend observed in the reduction of elemental carbon with removal of extractives in non-woody samples. In extractive-free samples, ash content decreases by 2–60%, fixed carbon content by 7–24% and calorific value by 1–17%. In conclusion, fuel properties of unextracted biomass are found to be better than extracted biomass.

Abstract


In this study, the effect of extractive content on fuel properties of selected woody and non-woody biomass samples has been evaluated. The results show significant variation in the amount of extractives (15–70%) present in different biomass samples. There is significant decrease in ash content, fixed carbon content and calorific value in extractive-free samples. The elemental carbon reduces after extraction in woody biomass. There is no specific trend observed in the reduction of elemental carbon with removal of extractives in non-woody samples. In extractive-free samples, ash content decreases by 2–60%, fixed carbon content by 7–24% and calorific value by 1–17%. In conclusion, fuel properties of unextracted biomass are found to be better than extracted biomass.
