Effects of biomass particle size on yield and composition of pyrolysis bio-oil derived from Chinese tallow tree (Triadica Sebifera L.) and energy cane (Saccharum complex) in an inductively heated reactor

In the face of fluctuating petroleum costs and a growing demand for energy, the need for an alternative and sustainable energy source has increased. A viable solution for this problem can be attained by using thermochemical conversion, pyrolysis, of existing biomass sources for the production of liquid fuels. This study focuses on the effect that biomass particle size has on the conversion of biomass into liquid pyrolysis oil. Energy cane and Chinese tallow tree biomass were pyrolyzed at 550 ℃. The particle size ranges studied were < 0.5, 0.5 to 1.4, 1.4 to 2.4 and, 2.4 to 4.4 mm. The results indicate that the range from 0.5-1.4 mm is a better range for optimizing bio-oil production while keeping water content low.
