| Abstract | In this study, cassava rhizome was converted to alternative biofuels including biocrude oil (BO) and hydrochar (HC) using catalytic hydrothermal liquefaction (C-HTL) at 250 and 300?Cfor 15 min using 4.0 wt.% of K2CO3as a catalyst. BO and HC properties were investigated regardingthe parametersof elemental composition, chemical functional groups, chemical compositions, and surface morphology. The maximum energy recovery efficiency (ERE) of sum product (83.98 wt.%) was derived at 300?C.Therefore, 300?Cwas suggested as a promising C-HTL temperature. This condition derived a yield of BO and HC at33.70 and 33.29 wt.%,with their Higher heating value(HHV)at26.45and 18.81MJ/kg, respectively.Gas chromatography -mass spectroscopy (GC-MS)analysis results indicated that BO principally contains phenols, aldehydes and ketones, hydrocarbons and alcohols which can be fractionated and upgraded into the biofuels and various valuable chemicals. The hydrogen/carbon (H/C)and oxygen/carbon (O/C)atomic ratios of BO and HC were similarto those of fossil fuel, indicating their high potential as fossil fuel substituting materials. |
