Poplar low-temperature carbonization method and application method of derived carbon

The invention discloses a low-temperature carbonization method for poplar and an application method of derived carbon. The low-temperature carbonization method for poplar comprises the following steps: S1, dipping poplar with ammonium phosphate; s2, the poplar soaked in the step 1 is filtered and dried; s3, the poplar filtered and dried in the step 2 is subjected to carbonization treatment; according to the application method of the poplar derived carbon, the derived carbon obtained through a poplar low-temperature carbonization method serves as a pyrolysis raw material to be pyrolyzed, and the pyrolysis reaction temperature ranges from 500 DEG C to 900 DEG C; according to the method, the poplar is loaded with different dosages of ammonium phosphate by using an impregnation method, compared with a traditional low-temperature carbonization treatment mode, parameters such as the mass production rate of a solid-phase product and the calorific value of the poplar charcoal solid-phase product are better than those
