Özet
<p>Previously, water hyacinth (<em>Eichornia crassipes</em>) was anaerobically digested with anaerobic sludge in batch system at varying total solid (TS) contents of 3.3 and 4.3% and at 35°C. In this study, high organic content of the digested biomass was evaluated in hydrothermal gasification in batch reactor system at different temperatures (200-500°C) to produce biofuels and biochemicals. Hydrothermal gasification was performed in sub- and super-critical water (Tc=374°C, Pc=221 bar) conditions. Prevailing products are biochemicals (glycolic acid, formic acid, acetic acid, furfural, 5-methyl furfural, phenols etc.) at lower temperatures (200-300°C) while biofuels (especially hydrogen and methane) are produced at higher temperatures (400-500°C). Nearly 63% of the feed was converted to gas and aqueous products at 500°C.</p>
