Diversifying the biomass feedstock for gasification is crucial to ensure the long-term development of this technology. In this context, rice husk is a promising feedstock thanks to its availability worldwide. In the first part of this book, we established an updated state-of-the-art of rice husk gasification, from domestics and industrial applications to research studies. In the second part, the gasification of rice husk char has been specifically investigated using a macro-thermogravimetric reactor, entirely designed and set up as part of this work. Results of this study could help researchers and engineers in the design, modeling, or optimization of a new efficient rice husk gasifier. Future research studies are highly recommended in both two directions: academic fundamental research at a laboratory scale and applied research at a pilot scale.
