Influence of alkali catalysts on product yield and Si-containing products from hydrothermal liquefaction of corn stover.

This study investigated the effects of different alkali catalysts (KCO, KOH, NaOH, and NaCO) on the yield and composition of biocrude oil and aqueous products obtained from hydrothermal liquefaction (HTL) of corn stover. HTL was performed in a laboratory-scale tubular reactor at 320 °C for 90 min and catalyst loading of 5.0 and 7.
