Abstract
The present study represents the conversion of biomass solid waste in the form of pine seed into bio-oil by solvent
extraction method. Hexane is used as solvent in this process which forms miscella (mixture of solvent and oil).
Solvent is recovered by distillation from miscella. The oil obtained was analyzed for their properties as an
alternative fuel and was compared with petroleum product and other biomass derived oil. The fuel properties
compared were higher calorific value, density and viscosity.
