P-19　Design and performance evaluation of gasification process using co-gasification of charcoal and biomass

Abstract

In the pyrolysis gasification process, a solid residue of carbon called Char, which is generated in a pyrolysis furnace, is burned with off-gas in a combustion furnace to produce the necessary amount of heat, and heat is supplied by circulating in HC However, the amount of heat loss is large. Therefore, we focused on designing a process using the gasification of biomass Char, the introduction of charcoal for the purpose of promoting gasification and bottom-up of the calorific value of synthesis gas is considered. There is concern that CO₂ emissions will increase when charcoal is introduced, but it is thought that the amount of CO₂ emissions per unit of purified hydrogen can be reduced. In order to evaluate the performance of the process, in this study, the gasification reaction rate was measured using a thermogravimetric rate experiment and the gasification process was designed.
