Embodiment 1
[0033]Step 1. First place the bituminous coal in a pulverizer to crush it into coal particles, and then place it in a planetary ball mill for ball milling to obtain a particle size D 90 ≤20μm coal powder;
[0034] Step 2: Carry out deashing treatment to the pulverized coal described in step 1. The specific process is: get 100mL acid solution and pour it into a plastic beaker, wherein the acid solution consists of 50mL deionized water, 30mL hydrochloric acid (37% by mass percentage) and 20mL acid solution. Hydrofluoric acid (mass percentage concentration 45%) is mixed evenly, and then 10g of coal powder is added to the acid solution according to the mass ratio of 1:10 and mixed evenly, and the temperature is continuously magnetically stirred for 0.5 h, then use a Buchner funnel to carry out suction filtration, and fully wash with deionized water until there is no chlorine ion remaining in the coal powder (the method of dripping silver nitrate solution can be used for inspection...
Embodiment 2
[0038] The difference between this example and Example 1 is that in step one, the coal rock components are obtained from the bituminous coal by the method of manual stripping, and then the coal rock components are first placed in a pulverizer to be crushed into coal particles, and then Place it in a planetary ball mill for ball milling to obtain a particle size D 90 Coal powder ≤ 20 μm, the coal rock component is vitrinite.
Embodiment 3
[0040] The difference between this example and Example 1 is that in step one, the coal rock components are obtained from the bituminous coal by the method of manual stripping, and then the coal rock components are first placed in a pulverizer to be crushed into coal particles, and then Place it in a planetary ball mill for ball milling to obtain a particle size D 90 Coal powder ≤ 20 μm, the coal rock component is silk group.
