Abstract

<p>Currently, carbon-neutral biomass fuels are attracting attention as an alternative fuel to fossil fuels from the perspective of combating global warming and realizing a sustainable society. However, biomass fuels have the problems of low energy density and high transportation costs. Therefore, we focused on biomass gasification technology. In this study, H2O gasification experiments were conducted with four different grain size samples using an electrically heated vertical batch furnace to investigate the effect of char grain size on the H2O gasification behavior of woody biomass char. As a result, there was almost no effect of char particle size on the reaction rate because the reaction proceeds by diffusion of the gasifier into the porous structure of the wood.</p>
