Example Embodiment
[0018] Example 1.
[0019] Step 1. The bagasse is crushed to a particle size of less than 5 cm; the red soil clay particles are passed through a sieve of more than 40 mesh for use.
[0020] Step 2. Dissolve 5 parts of phosphoric acid and 0.5 part of sulfuric acid in 200 parts of water to obtain an acidic mixed solution. Spray the acidic mixed solution evenly into 100 parts of bagasse raw material treated in step 1, mix and stir evenly, and then to the wet bagasse Sprinkle 100 parts of the red soil clay treated in step 1 into the raw material and stir evenly to obtain the pretreated bagasse raw material.
[0021] Step 3. Take the bagasse raw material pretreated in Step 2, and crack it in a screw-propelled continuous biomass microwave cracking device. Continuously push to the reaction part with a screw pushing device, set the energy-saving state of the microwave cracking temperature and power of 450 ℃ ± 10 ℃, the total reaction time of bagasse after the reaction part is 40 minutes, an...

[0023] Example 2.
[0024] Step 1. The straw is crushed to a particle size of less than 5 cm; the montmorillonite is passed through a sieve of 40 mesh or more for use.
[0025] Step 2. Dissolve 7 parts of phosphoric acid and 0.2 part of sulfuric acid in 200 parts of water to obtain an acidic mixed solution. Spray the acidic mixed solution evenly into 100 parts of the straw material treated in step 1, mix and stir evenly, and then to the wet straw Sprinkle 150 parts of the montmorillonite treated in step 1 into the raw material, and stir evenly to obtain the pretreated straw raw material.
[0026] Step 3. Take the straw raw material pretreated in step 2 and crack it in a screw-propelled continuous biomass microwave cracking device. Continuously push to the reaction part with a screw pushing device, set the energy-saving state of microwave pyrolysis temperature and power of 480℃±10℃, the total reaction time of rice straw passing through the reaction part is 35min, and collect liquid p...
Example Embodiment
[0028] Example 3.
[0029] Step 1. The bamboo waste is crushed to a particle size of less than 5 cm; the kaolin is passed through a sieve of more than 40 mesh for use. Step 2. Dissolve 10 parts of phosphoric acid and 0.5 part of sulfuric acid in 200 parts of water to obtain an acidic mixed solution. Spray the acidic mixed solution evenly into 100 parts of the bamboo waste material treated in step 1, mix and stir evenly, and then moisten it. Sprinkle 200 parts of the kaolin processed in step 1 into the bamboo waste raw material, and stir evenly to obtain the pretreated bamboo waste raw material.
[0030] Step 3. Take the bamboo waste material pretreated in Step 2, and crack it in a screw-propelled continuous biomass microwave cracking device. Continuously push to the reaction part with a screw pushing device, set the energy-saving state of microwave cracking temperature and power of 500℃±10℃, the total reaction time of bamboo waste after the reaction part is 35min, and collect liqu...
