Embodiment 1
[0108] A process for producing fuel oil and chemical raw materials from biomass, comprising the steps of:
[0109] Biomass Pretreatment
[0110] Put the rice straw into the dryer and dry at 60°C for 4 hours until the water content is lower than 2wt%, and then send it into the superfine pulverizer for primary crushing, the median particle size after primary crushing is 200 μm, and then the primary crushed The rice straw is fed into the plodder to be compressed and extruded at a temperature of 50°C and a pressure of 2 MPa, and then subjected to secondary crushing treatment. The median particle size after secondary crushing is 40 μm, and the rice straw after secondary crushing is Straw bulk density is 440kg / m 3 ,spare.
[0111] Preparation of the first catalyst
[0112] (1) selecting biochar as the first biochar carrier;
[0113] (2) Loading iron oxide on the above-mentioned first biomass charcoal carrier to prepare the first catalyst.
[0114] The concrete method that ir...
Embodiment 2
[0131] A process for producing fuel oil and chemical raw materials from biomass, comprising the steps of:
[0132] Biomass Pretreatment
[0133] Put the wheat straw and reed straw into the drier and dry at 62°C for 4.5h 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 220 μm, and then The primary crushed wheat straw and reed straw are sent to the briquetting machine for compression extrusion molding at a temperature of 50°C and a pressure of 1MPa, and then undergo secondary crushing.

Embodiment 3
[0153] A process for producing fuel oil and chemical raw materials from biomass, comprising the steps of:
[0154] Biomass Pretreatment
[0155] Put cotton stalks and corn stalks into a dryer and dry them 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 pulverized cotton stalks and corn stalks were fed into a plodder for compression extrusion molding at a temperature of 30°C and a pressure of 3 MPa, and then secondary pulverization. The median particle size after secondary pulverization was 30 μm. The bulk density of cotton stalks and corn stalks after secondary crushing is 500kg / m 3 ,spare.
