UTILIZATION OF WASTE GLYCEROL FROM BIODIESEL PRODUCTION AS CATALYST FOR SUPERCRITICAL WATER GASIFICATION

摘要

In this study, waste glycerol from biodiesel pretreatment was tested as catalyst for the supercritical water gasification. Hydrogen fermentation solid residue of food waste (FW-HFSR) was gasified in the supercritical water gasification reactor with and without FW-HFSR. The FW-HFSR showed good catalytic effect. Considering reagent glycerol does not show any catalytic effect, KOH in waste glycerol should have worked as catalyst. Based on this finding, first-order rate equation has been developed, and good agreement with experimental result.
