Experimental Observation on Downdraft Gasification for Different Biomass Feedstocks

Abstract

With the need for developing a more sustainable world, there is a desire to shift from fossil fuels to biofuels, produced using the concept of biorefineries. Within the last few decades, thermochemical conversion technologies have gained a great deal of attention for producing advanced biofuels. In this context, this chapter elaborates different aspects of biomass gasification technology, as a representative of thermochemical pathways, and suggested potential solutions to enhance the efficacy of the process. To fulfill this goal, different types of biomass feedstock are employed to examine the potential of each in bioenergy production through gasification process. The chapter is consisting of a series of dependent studies to investigate the path for advancements in the gasification process. The first study investigates the parametric effect of experimental conditions during gas ification of individual biomass feedstocks to select the best biomass feedstock for next study. It is also demonstrated that how the variation in the syngas composition inter acts with H 2 /CO ratio. The other study investigates the potential of composite feedstocks based on the results from the first study. The last study investigates the potential failure scenarios and the likelihood of their occurrence are explored.
