Operating parameters for bio-oil production in biomass pyrolysis: A review

摘要

The use of renewable energy sources is becoming increasingly necessary. Biomass is considered to have potential to be used as an alternative energy source. The bio-oil obtained of biomass pyrolysis is used as fuels and chemicals products. The yield and composition of pyrolysis oil depend on biomass composition and operating parameters of the process. This review was written with a focus on parameters that influence the process, such as temperature, reaction time, heating rate, gas flow rate, feed rate, particle size and biomass composition and discusses the effect of these parameters on the yield and quality of bio-oil. Besides that, a database with different types of biomass analyzed under different operating conditions that interfere with the pyrolysis process was obtained from 206 research on the pyrolysis process found in the literature. This database can be used for a better understanding of how the composition of the biomass and the parameters of the pyrolysis process interfere with the composition and yield of the obtained products.
