Studies on influence of process parameters on hydrothermal catalytic liquefaction of microalgae (Chlorella vulgaris) biomass grown in wastewater.

In this study, liquefaction of Chlorella vulgaris biomass grown in photo-bioreactor using wastewater as source of nutrition was studied and influence of process parameters on the yield of bio-oil was analysed. Different biomass to water ratio (5g/200ml, 10g/200ml, 15g/200ml, and 20g/200ml) was taken and bio-oil yield at various temperatures ranging from 220 to 340°C was studied. Catalyst loading of the range 2.
