Pyrolysis and Steam Gasification of Biomass Waste for Hydrogen Production

Through promising thermochemical technologies, hydrogen, the unavoidable future fuel, can be produced from biomass. Fast pyrolysis followed by steam reforming of bio-oil, supercritical water gasification, and steam gasification are examples of modern thermochemical hydrogen-generating technologies. Apart from the aforementioned approaches, a new process combining slow pyrolysis and steam gasification can be used to produce hydrogen with higher yield and purity. This chapter gives an insight into the combined slow pyrolysis and steam gasification process for hydrogen production and the numerous factors that influence the integrated slow pyrolysis and steam gasification process. It also discusses the products of pyrolysis and gasification.
