Abstract

To investigate the effect of ammonium dihydrogen phosphate （MAP） on the quality of pyrolysis products of poplar and its derived charcoal, revealing the factors presented by MAP for improving poplar quality and catalytic tar cracking. Select MAP impregnation solutions of different concentrations for in-situ impregnation loading into poplar for low-temperature carbonization and derived carbon pyrolysis experiments. Study the influence of different MAP concentrations on the three-phase yield, biochar calorific value, and energy yield of poplar carbonization. Investigate the catalytic cracking phenomenon of derivative carbon pyrolysis with the addition of MAP compared with the direct pyrolysis of raw materials. The results indicate that low-temperature carbonization combined with the addition of MAP has a synergistic effect on the increase of poplar pyrolysis char and the decrease of tar, When the pyrolysis temperature is 500 ℃, Compared to the absence of derivative carbon, the addition of 1.975% MAP derivative carbon results in a 19.8% decrease in phenolic products and a 5.38% decrease in toluene products in the tar component. This study can provide a basis for the preparation and application of high-quality and relatively clean derived carbons.
