Abstract

Fast pyrolysis of rice husk was carried out in a fixed-bed reactor for bio oil production. In this work rice husk was characterized for proximate and ultimate analysis and the result shows volatile matter of rice husk to be 70.66% with elemental compositions of carbon and oxygen as 42.68% and 42.414% respectively. Design expert software was used in planning and optimized experimental results. The experimental runs were conducted using o retention time of 6omin and the optimum conditions for fast pyrolysis of rice husk with maximum bio-oil yield of 62.8% were at the rcr4peraturc of 600oC, N2 gas flow rate of 5 L/min and particle size of 1.7 mm. Particle size, temperature and bio oil yield of 64.7%. The bio oil obtained at optimal conditions was analyzed using GC-MS to identify its compounds. GC-MS peak area percentage showed that the bio oil exhibited a variety of chemical groups and it was determined that the dominant chemical group was Phenol
