Abstract: “Biomass in the form of saw-dust widely available in Brunei Darussalam from different timber industries is characterized in order to be used as feedstock for its conversion into bio-oil by the emerging thermochemical process, known as pyrolysis. It has dual effects. In one way, it reduces too much dependency on fossil fuel sources with a diversion of attention towards renewable sources of energy. On the other hand, it contributes to the reduction of pollution and disposal problems which are at present a major concern of every nation along with the whole world. For this purpose, locally available saw-dust solid waste is collected, prepared and characterized for its thermal behavior by means of thermo-gravimetric analysis (TGA). From the study it is realized that the solid saw-dust particles can be used as a feedstock material for its pyrolytic conversion into bio-oil with sufficient percentage of liquid and solid product yields. The study indicates that the pyrolysis reactor bed temperat”
