Embodiment 1
[0069] A joint hydrolysis and hydrogenation process of coal and biomass, comprising the following steps:
[0070] Lignite was taken, dried and dehydrated, crushed to a median particle size of 100 μm, and then sent to a briquetting machine for extrusion molding at a molding pressure of 15 MPa to obtain a lignite compressed material. The compressed lignite material is sent to a hammer mill for pulverization to obtain a pulverized lignite material with a particle size of 30 μm. The above-mentioned pulverized lignite material and the amorphous ferric oxyhydroxide after sulfidation treatment in the reactor are added to the mixture of feces and water to form a biomass coal-water slurry, and hydrogen gas is passed into the biomass coal-water slurry to generate react, and control the reaction pressure to 16 MPa, the reaction temperature to 420° C., and react for 35 minutes to finally obtain bio-oil.
Embodiment 2
[0072] A joint hydrolysis and hydrogenation process of coal and biomass, comprising the following steps:
[0073] Straw pretreatment:
[0074] (1) Take the straw, dry and dehydrate it, crush it to a median particle size of 100 μm, and then send it to a briquetting machine or a plodder for extrusion molding at a molding pressure of 2 MPa to obtain a compressed straw material.
[0075] (2) Send the compressed straw material into a hammer mill for crushing to obtain crushed straw material with a median particle size of 30 μm, which is ready for use.
[0076] Pretreatment of coal raw materials:
[0077] (1) Take lignite, dry and dehydrate it, pulverize to a median particle size of 100 μm, and then send it to a briquetting machine for extrusion molding at a molding pressure of 5 MPa to obtain lignite compressed material.
[0078] (2) Send the compressed lignite material into a ball mill for pulverization to obtain a pulverized lignite material with a median particle size of 10...
Embodiment 3
[0088] A joint hydrolysis and hydrogenation process of coal and biomass, comprising the following steps:
[0089] Pretreatment of biomass raw materials:
[0090] (1) Get the reed, dry and dehydrate it, and then send it to the jet mill for crushing to obtain the primary crushed material of the reed, with a particle size of D 50 is 200 μm.
[0091](2) Send the reed primary pulverized material into a briquetting machine or a plodder for extrusion molding with a molding pressure of 3 MPa to obtain a reed compressed material.
[0092] (3) The reed compressed material is sent into the jet mill, and secondary pulverization is carried out to obtain the reed secondary pulverization material, particle size D 50 40 μm, set aside.
[0093] Pretreatment of coal raw materials:
[0094] (1) Take Shendong long-flame coal, dry and dehydrate it, and then send it to a ball mill for crushing to obtain primary crushed material of Shendong long-flame coal, particle size D 50 is 80 μm.
