Digested water hyacinth with activated sludge as
inoculum were obtained after anaerobic digestion at 35 and 45°C.
High organic content of digested biomass were evaluated through gasification at
supercritical conditions of water in the absence and presence of catalysts
(KOH, NaOH, LiOH and K2CO3)
with 10 wt.% of volatile solid in feed.
Supercritical water gasification of digested biomass was performed in batch
reactor system at temperature and pressure ranges of 500–600°C
and 350–450
bar, respectively. The highest
carbon gasification efficiency, hydrogen and methane yields were reached at 600°C
(with samples 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 12.5 (mol CH4%),
respectively. High organic content of digested biomass was converted by
supercritical water gasification to hydrogen and methane 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.
