Abstract
Digested water hyacinth with waste sludge as inoculum were obtained after anaerobic digestion at 35 and 45°C. High organiccontent of digested biomass were evaluated through gasification at supercritical conditions of water in the absence andpresence of catalysts (KOH, NaOH, LiOH and K2CO3) with 10 wt.% of volatile solid in feed. Supercritical water gasificationof digested biomass was performed in batch reactor system at temperature and pressure ranges of 500–600°C and 35–45MPa, respectively. The highest carbon gasification efficiency, hydrogen and methane yields were reached at 600°C (withsamples digested at 45°C) in the absence of catalyst as 84.6 (g C in gaseous/g C in digestate), 53.0 (mol $H2%$) and 14.2 (mol$CH4%$), respectively. High organic content of digested biomass was converted by supercritical water gasification to methaneand hydrogen rich gas, and aqueous products (aliphatic hydrocarbons, phenol, substituted phenols, N-heterocyclic,substituted N-heterocyclics, and substituted benzene) that can be evaluated as platform chemicals.
