Bioenergy is now accepted as having the potential to provide the major part of the projected renewable energy provisions of the future. Fast pyrolysis is one of the three main thermal routes, with gasification and combustion, to providing a useful and valuable biofuel. It is strongly believed that the product of the Pyrolysis can be further enhanced by using microwave as a decomposition method. Microwave has a better and cleaner heating distribution during heating as what is explained in the literature review section. The power consumed by the microwave effects the decomposition rate of the biomass. Different decomposition rate will affect in changes in the product distribution. Thus, the objective of this project is to study the characteristic of bio-oil produced by microwave induced Pyrolysis and the results will be compared within the different sizes, power input and also with those from thermal decomposition. Literature reviews on similar experimental works, equipments and devices and simulations are reviewed for better understanding and to improve current ideas on this project. A lot of the experiments conducted previously involve the decomposition of biomass using other form of thermal decomposition are also reviewed. The methodology, which keeps track of the project work, shows the project is completed on time. Experiment setup shows how the microwave reactor is adjusted and reoriented to better distribute the results of the decomposition. The project proceeds with data analysis, where the CHNS analysis, calorific value analysis and also the ash content analysis will be carried out using the CHNS equipment, Bomb Calorie Meter and also Muffle Furnace. Trends are constructed to compare the characteristic of the bio-oil using different input powers and different sizes of biomass. From the results, it is clear that Pyrolysis through microwave is more effective compared to conventional heating, with lower Pyrolysis temperature and higher Bio-oil Quality (Higher calorific value and carbon content). With the best microwave reactor operating condition of 1kW of power input and maintains the temperature at 350oC.
