Embodiment 1
[0029] Example 1 This example provides a method for bio-heavy oil from corn stalks
[0030] 1) The contents of cellulose, hemicellulose, lignin and ash in corn stalks are 32wt%, 15wt%, 18wt% and 35wt%, respectively. The specific steps of biomass liquefaction are: collect 10kg of corn stalks, and its moisture content is 10wt %, after mechanical treatment, the particles are less than 20mm, and they are put into the reactor by vacuum feeding to ensure that the oxygen volume content is lower than 1%; the mass ratio of water and ethanol in 50kg of water supply solvent is 1:2, and the mass of sulfuric acid is 1.3% of the water co-solvent mass is 0.663kg98% concentrated sulfuric acid, the ratio of straw to liquid is 1:5, react at 160°C for 20 minutes, the cellulose, hemicellulose and lignin in the corn straw are all liquefied, The solid residue is 35wt% ash in the biomass, adding 1kg of 50% calcium hydroxide slurry to neutralize the sulfuric acid in the solution, and filtering to obt...
Embodiment 2
[0039]Embodiment 2 pine wood
[0040] This embodiment provides a method for liquefaction of pine wood to produce heavy biological oil. The cellulose in pine wood, hemicellulose, lignin and ash content are 32wt%, 25wt%, 18wt% and 5wt%, respectively. Biomass liquefaction, specifically The steps are: collect 10kg of pine wood chips with a moisture content of 5wt%, after mechanical treatment, the particle size is less than 20mm, and put them into the reaction kettle by vacuum feeding, and add 70kg of water co-solvent, the mass ratio of wood chips to liquid is 1: 7. The mass ratio of water and furan in the water co-solvent is 1:2, the mass of sulfuric acid is 2.0% of the mass of the water co-solvent, that is, 1.663kg of 98% concentrated sulfuric acid, and react at 200°C for 30 minutes. The cellulose, hemicellulose and lignin of pine wood chips were all liquefied, and the solid residue was 5wt% ash. Add 2.4kg50% calcium hydroxide slurry to neutralize the sulfuric acid in the soluti...
