Embodiment 1
[0073] The method for direct liquefaction of biomass provided by the embodiments of the present invention comprises the following steps:
[0074] (1) The biomass 1 enters the biomass pretreatment device 2 to be dried and pulverized sequentially to obtain pulverized materials with a particle size of 10 μm, wherein the pulverized materials are wheat straw particles;
[0075] (2) The hydrogenation catalyst raw material 3 enters the hydrogenation catalyst preparation device 4 for loading, and obtains a hydrogenation catalyst (its particle size is 20 μm, and the loading capacity is 15 wt %) loaded with Mo oxide and Ni oxide on the amorphous alumina. , mixing the hydrogenation catalyst, the pulverized material and sulfur in the biomass slurry preparation device 5 at a mass ratio of 3:100:0.3 to obtain the mixed material;
[0076] (3) mixing the mixture with a hydrogen-donating solvent to obtain a biomass slurry with a solid content of 25 wt%, wherein the hydrogen-donating solvent is...
Embodiment 2
[0085] The method for direct liquefaction of biomass provided by the embodiments of the present invention comprises the following steps:
