Abstract

To make synthetic liquid fuel from biomass such as wood pellet, energy crop and so on, a biomass to liquid (BTL) process by using a biomass gasifier with Fisher-Tropsch (FT) reaction was developed. However $H_2S$, COS and $CO_2$ in syngas from biomass gasifiers resulted in a decrease of the conversion efficiency and the deactivation of the catalyst. To remove acid gases in syngas, a lab-scale methanol absorption tower was developed and the removal characteristics of acid gases were investigated. The methanol absorption tower efficiently removed $H_2S$ and COS with a removal of $CO_2$, so it could be useful process for the BTL process.
