Embodiment 1
[0022] Embodiment 1, preparation and application of asphalt modifier
[0023] 1. Preparation of asphalt modifier
[0024] Add 1 mass part of coal and 1.5 mass parts of catalytic cracking oil slurry into the reactor, add ferrous sulfate to react, in terms of metal elements, the quality of ferrous sulfate accounts for 1% of the total mass of coal; the reaction conditions are: nitrogen The pressure was 4 MPa, and the reaction was carried out at 450° C. for 5 hours. After the light products are separated, the heavy residue is bitumen modifier, and the by-products are light oil and hydrocarbon-rich gas.
[0025] After the reaction is completed, the total mass of all products obtained is taken as 100%, including 73.2% of asphalt modifier, 23.7% of light oil and hydrocarbon-rich gas, and 3.1% of water.
[0026] 2. Application of road asphalt modifier
[0027] Grinding the asphalt modifier prepared in step 1 to a size below 5 microns. 15 parts by mass of the pulverized asphalt mod...
Embodiment 2
[0029] Embodiment 2, preparation and application of asphalt modifier
[0030] 1. Preparation of asphalt modifier
[0031] Put 0.5 parts by mass of coal and 1 part by mass of catalytic cracking oil slurry into the reactor, add molybdenum sulfide to react, and the mass of molybdenum sulfide accounts for 0.4% of the total mass of coal in terms of metal elements; the reaction conditions are: nitrogen pressure 10MPa , 400°C for 0.5 hours. After the light products are separated, the heavy residue is bitumen modifier, and the by-products are light oil and hydrocarbon-rich gas.
[0032] After the reaction is completed, the total mass of all products obtained is taken as 100%, including 62.7% of asphalt modifier, 35.8% of light oil and hydrocarbon-rich gas, and 1.5% of water.
[0033] 2. Application of asphalt modifier
[0034] Grinding the asphalt modifier prepared in step 1 to a size below 5 microns. 25 parts by mass of the pulverized asphalt modifier and 75 parts by mass of 90# ...
Embodiment 3
[0036] Embodiment 3, preparation and application of asphalt modifier
[0037] 1. Preparation of asphalt modifier
[0038] Add 1 mass part of coal and 1 mass part of catalytic cracking oil slurry into the reactor, and add pyrite to react. In terms of metal elements, the quality of pyrite accounts for 2% of the total mass of coal; the reaction conditions are: nitrogen The pressure was 8 MPa, and the reaction was carried out at 425°C for 2 hours. After the light products are separated, the heavy residue is bitumen modifier, and the by-products are light oil and hydrocarbon-rich gas.
[0039] After the reaction is completed, the total mass of all products obtained is taken as 100%, including 63.8% of asphalt modifier, 33.4% of light oil and hydrocarbon-rich gas, and 2.8% of water.
[0040] 2. Application of asphalt modifier
[0041] Grinding the asphalt modifier prepared in step 1 to a size below 5 microns. 20 parts by mass of the pulverized asphalt modifier and 80 parts by ma...
