| Abstract: | Large-scale fast pyrolysis of biomass to produce bio-oil will be an important technology to solve the problem of liquid fuel shortage.This paper starts with a summary of the feedstock pretreatment requirements for pyrolysis.Next,the recent applications of various pyrolysis reactors are reviewed,the autothermal pyrolysis technique by utilizing the byproducts(char and fuel gas)and the key problems involved are discussed,followed by a discussion on the best autothermal techniques based on three well developed pyrolysis reactors.The techniques associated with solid separation from the pyrolysis vapor and condensation of bio-oil are presented.In the end,the environment/health issues related to bio-oil production,storage and transportation are discussed. |
