n order to suppress greenhouse gas emission and avoid global warming, utilization of biomass energy as a substitute for
fossil fuels has attracted attention in recent years due to its renewability and carbon neutrality. Biomass gasification and
pyrolysis has been investigated as one of the technologies for efficiently utilization of biomass energy. However, gasification
characteristics of biomass varies according to the types of that. It is necessary to clarify the gasification characteristics of
biomass due to practical use of various biomass. Here, the effects of various biomass on gasification behaviors are discussed.
In this study, pyrolysis and gasification experiments were carried out using a batch type tubular reactor. Cedar and cypress of
coniferous trees, eucalyptus of hardwood and bamboo of grass-type biomass were used as biomass feedstock. These biomass
were pulverized and sieved to 0.5 to 1 mm. The sample was put on the ceramics boat and installed in the reactor. The reaction
temperature was electrically controlled and set from 600 to 900
o
C. The reaction atmosphere was inert only or both inert
and steam, and the products were removed from the reactor by carrier gases. The experimental results showed that each
biomass species had a different characteristic of gasification. The yields of char produced from the broadleaf eucalyptus and
the grass-type biomass bamboo were higher than these of the coniferous wood. This tendency was common in all experimental
conditions. The gas yield of bamboo was the lowest result in all biomass feedstocks. For all biomass, on the other hand, the
gas yields increased and the tar yields decreased by the addition of steam. Especially improvement of the hydrogen yields was
remarkable. It was suggested that steam reforming of the tar was promoted under the atmosphere containing water vapor.
