Carbonization Experimental runs on carbonization of the biomass material were performed in a batch carbonizer, as shown in Figure 1. The carbonization reactor was cylindrical shaped with 1.2 m high and inside diameter of 0.6 m. It was made of a used oil drum, surrounded on the inside by thick insulating wool and a 3 mm thick steel sheet. It had a centrally located pyrolysis gas burner inside the cylinder. The burner tube had six radial fins attached to it to provide large heat transfer surface. Two tangential air ports were connected to the bottom end of the gas burner. There was a fixed grate near the bottom with other two air ports connected underneath the combustion chamber. The samples were cut into size range of 30 – 50
