Elementary and X-Ray Fluorescence analysis were used to investigate the elemental component of Kraft lignin. Kraft lignin was valorized in water-ethanol mixture (v（water）:v（ethanol）=50:50) with 2 MPa initial H2 pressure. FT-IR was used for the analysis of the structure of Kraft lignin before and after reaction, and the results showed that ether bond decreased while C-H bond increased in the products. The monomer products were qualitative and quantitative analyzed with GC-MS and GC-FID, respectively. The total yield of monophenols was 4.57 wt% without catalyst. The introduction of Ni2P doubled the monophenols yield. When MoP was used as the catalyst, the yield of monophenols is similar to that obtained through Ni2P catalyzed process. However, benzyl alcohols and considerable amount of linear oxygen-containing organics were observed, leading to decrease of monophenols selectivity.
