Syngas Production from Biomass: A Review

Biomass is a promising energy resource, due to it is renewable and potentially zero carbon dioxide emissions. Biomass gasification is a major technical option to produce syngas, syngas can be further used as feedstock to product heat and power or bio-gasoline. A lot of research works have been made in biomass-derived syngas production for many years.
