Pyrolytic Oil of Banana (Musa spp.) Pseudo-stem via Fast Process

This study was an attempt to produce bio-oil from banana pseudo-stem, a waste of banana cultivation, using fast pyrolysis technology. The compositions were determined and the thermal degradation behaviour of the raw material was analyzed using Perkin-Elmer Simultaneous Thermal Analyzer.(STA) 6000. A 300 g/h fluidized bed bench scale fast pyrolysis unit, assembled with double screw feeders and cyclones, operating at atmospheric pressure, was used to obtain the pyrolysis liquid. The study involves the impact of the following key variables; the reactor temperature in the range of 450-650 degrees C, and the residence time in the range of 1.00-3.00s. The particle size was set at 224-400 mu m. The properties of the liquid product were analyzed for calorific heating value, pH value, conductivity, water and char content. The basic functional groups of the compositions were also determined using FTIR. The properties of the liquid product were compared with other wood derived bio-oil. The pyrolysis liquids derived from banana pseudo-stem were found to be in an aqueous phase.
