The aim of this study was to investigate the essence of deoxy-liquefaction technology by the comprehensive analysis of several aquatic plants鈥?(AP) deoxy-liquefaction from the element and energy points of view. Accompanied by the oxygen removal in the form of CO2 and H2O, a great amount of hydrogen and carbon was shifted into water and char, leading to the low yield of liquid oil (LO) (11.23鈥?6.70%). However, the residue carbon and hydrogen were adjusted to form mainly gasoline/diesel oil fractions and phenols. The deoxy-liquefaction was a similar miniature of the underground evolution from biomass to petroleum and coals during hundred thousands of years. The energy lost in the system was 5.6% and 19.9% based on the elemental balance of Nelumbo nucifera leaves (AP1) and Arundo donax (AP6). The closed system with the pressure of 8鈥?0 MPa and the temperature of 350鈥?00 掳C made the decomposition pathway different from the traditional thermal conversion.
