Pyrolysis of biomass

Abstract

Pyrolysis of biomass is considered to be a green technology since it has no impacts or emissions to the environment. Pyrolysis of biomass is the initial stage in the gasification process and is defined as the thermal decomposition of biomass into valuable products such as char, tar, and gas. In this study, a pyrolysis reactor was designed and constructed, and experimental tests were performed to study the pyrolysis products, especially the gas compositions. An extensive literature study has been carried out on the pyrolysis of biomass along with the effects of different operational conditions on the product yields. Further, computational particle fluid dynamic (CPFD) simulations were performed to study the composition of the synthesis gas obtained from the gasification of wood pellets.
