In HTL processing of complex biomass feeds, the product distribution, composition,
and properties are highly dependent on the process parameters and on the
composition of the processed biomass. Since a broad variety of biomasses are accepted
by the HTL process, the parameter space is immense and far from fully
explored. Based on experimental results reported in literature, this section aims
on providing insight into a selection of process parameters and their influence in
hydrothermal conversion of biomass.
