The conversion of pine seeds into pyrolytic oil by fixed bed reactor has been taken into consideration in this study. A fixed bed pyrolysis system has been designed and fabricated for obtaining liquid fuel from biomass solid wastes. The major components of the system are: fixed bed reactor, liquid condenser and liquid collectors. The reactor is heated by means of a cylindrical biomass source heater. Rice husk, cow dung and charcoal are used as the energy source. The products are oil, char and gas. The aim of the study was to compare the pyrolysis oil with fossil oil and to come up a decision about usage of pyrolysis oil as an alternative to fossil oil. By the experiment it is found that the pyrolysis oil can be used as fossil oil after some treatments.
