Embodiment 1
[0025] Embodiment 1: The hydrogenation liquefaction method of this high-content inert component coal is carried out according to the following steps:
[0026] The first step of swelling treatment: N-methylpyrrolidone (NMP), N,N-dimethylformamide (DMF) and carbon disulfide (CS 2 ) mixed with Wucaiwan coal at a ratio of 2:1 while stirring, sealed and left to swell for 0.5 hours at room temperature, vacuum filtered and dried to obtain swelled coal; wherein, N-methylpyrrolidone (NMP) , N, N-dimethylformamide (DMF) and carbon disulfide (CS 2 ) to form a mixed solution with a volume ratio of 1:0:1, and the ratio unit of the above mixed solution to Wucaiwan coal is ml / g;
[0027] The second step of hydrogenation liquefaction reaction: the required amount of the above-mentioned swelling coal, catalyst ferric oxide, cocatalyst elemental sulfur and hydrogen-donating solvent tetrahydronaphthalene are mixed evenly and poured into the reactor, and the reactor is sealed and poured into the...
Embodiment 2
[0029] Embodiment 2: the hydrogenation liquefaction method of this high-content inert component coal is characterized in that it is carried out according to the following steps:
[0030] The first step of swelling treatment: N-methylpyrrolidone (NMP), N,N-dimethylformamide (DMF) and carbon disulfide (CS 2 ) mixed with Wucaiwan coal at a ratio of 10:1 while stirring, sealed and left to swell for 24 hours at room temperature, vacuum filtered and dried to obtain swollen coal; wherein, N-methylpyrrolidone (NMP) , N, N-dimethylformamide (DMF) and carbon disulfide (CS 2 ) to form a mixed solution with a volume ratio of 2:0 to 1:1, and the unit of the ratio of the above mixed solution to Wucaiwan coal is ml / g;
[0031] The second step of hydrogenation liquefaction reaction: the required amount of the above-mentioned swelling coal, catalyst ferric oxide, cocatalyst elemental sulfur and hydrogen-donating solvent tetrahydronaphthalene are mixed evenly and poured into the reactor, and t...
Embodiment 3
[0033] Embodiment 3: the hydroliquefaction method of this high-content inert component coal is carried out according to the following steps:
[0034] The first step of swelling treatment: N-methylpyrrolidone (NMP), N,N-dimethylformamide (DMF) and carbon disulfide (CS 2 ) mixed with Wucaiwan coal at a ratio of 2 to 10:1 while stirring, then sealed and left to swell for 0.5 to 24 hours at room temperature, vacuum filtered and dried to obtain swollen coal; wherein, N-formazol Nylpyrrolidone (NMP), N, N-dimethylformamide (DMF) and carbon disulfide (CS 2 ) to form a mixed solution with a volume ratio of 1 to 2:0 to 1:1, and the ratio of the above mixed solution to Wucaiwan coal is in ml / g;
[0035] The second step of hydrogenation liquefaction reaction: the required amount of the above-mentioned swelling coal, catalyst ferric oxide, cocatalyst elemental sulfur and hydrogen-donating solvent tetrahydronaphthalene are mixed evenly and poured into the reactor, and the reactor is seale...
