The invention discloses a process for preparing liquid biological energy of tung oil cake, which comprises the following steps: first, processing tung oil cake into powder for 20 orders-80 orders, second, directly thermally cracking tung oil cake powder under the oxygen-free condition, the temperature of thermal cracking is 180 DEG C-890 DEG C, cooling thermal cracking air at room temperature, then obtaining pyrolytic oil of tung oil cake, third, obtaining liquid biological energy of tung oil cake after separating and evaporating pyrolytic oil of tung oil cake and cooling evaporant under the vacuum condition with the temperature of 9-116 DEG C and 0-0.96MPa, remains are solid energy, and conversion rate is more than 56%. The liquid biological energy of tung oil cake is friendly to the environment, which has wide application prospect in the renewable energy field of forests. The method which is provided by the invention has relatively simple operating technology, low cost, excellent controllability and easy in
