Embodiment 1
[0048] A biomass hydrolysis hydrogenation process, comprising the steps of:
[0049] Biomass Pretreatment
[0050] Put rice straw and reed straw into a drier and dry at 50°C for 5 hours until the water content is lower than 2wt%, and then send them into an ultrafine pulverizer for primary crushing. The median particle size after primary crushing is 100 μm, and then the primary The crushed rice straw and reed straw were fed into a briquetting machine for compression extrusion molding at a temperature of 30°C and a pressure of 3 MPa, and then secondary crushing was carried out. The median particle size after secondary crushing was 30 μm. The bulk density after the first crushing is 500kg / m 3 ,spare.
[0051] Catalyst preparation
[0052] (1) take biochar as biochar carrier;
[0053] (2) loading iron oxide on the above-mentioned biomass charcoal carrier, and performing sulfuration treatment to prepare the catalyst.
[0054] The concrete method that iron oxide is loaded on...
Embodiment 2
[0063] A biomass hydrolysis hydrogenation process, comprising the steps of:
[0064] Biomass Pretreatment
[0065] Put the wheat straw and corn straw into the dryer and dry at 70°C for 3 hours until the water content is lower than 2wt%, and then send them into the superfine pulverizer for primary crushing, the median particle size after primary crushing is 300 μm, and then the primary crushing The crushed wheat straw and corn straw are fed into a briquetting machine for compression extrusion molding at a temperature of 60°C and a pressure of 0.5 MPa, and then secondary crushing is carried out. The median particle size after secondary crushing is 50 μm. The bulk density after secondary crushing is 400kg / m 3 ,spare.

Embodiment 3
[0078] A biomass hydrolysis hydrogenation process, comprising the steps of:
[0079] Biomass Pretreatment
[0080] Cotton stalks are dried, and the cotton stalks are sent into a drier and dried at 60°C for 4 hours until the water content is lower than 2wt%, and then sent to an ultrafine pulverizer for primary crushing. The median particle size after primary crushing is 200 μm, and then The cotton stalks after the primary crushing are sent to the plodder for compression extrusion molding at a temperature of 40°C and a pressure of 2 MPa, and then secondary crushing is carried out. The median particle size after the secondary crushing is 40 μm. The final bulk density is 450kg / m 3 ,spare.
[0081] Catalyst preparation
[0082] (1) take biochar as biochar carrier;
[0083] (2) Ferric hydroxide and ferric oxyhydroxide are supported on the above-mentioned biomass charcoal carrier, and sulfurized to prepare the catalyst.
