P-14 Effect of feedstock concentration on supercritical water gasification of shochu residue with acetic acid addition

Abstract

The main objective of this research is to study the effect of feedstock concentration on supercritical water gasification of shochu residue with addition of acetic acid. It was reported in previous study that yield of char or tar decreased in the presence of acetic acid. However, the effect of feedstock concentration is still unclear. In this study. the experiment was conducted at 600 ℃, 25 MPa, changing concentrations of shochu residue between 0.1 and 0.5 wt%. The liquid product was analyzed using total organic carbon (TOC) analyzer, while gas product was analyzed using gas chromatography (GC). In the result, the tendency with changing concentrations of shochu residue.
