Embodiment 1
[0028] Step 1. Mix the Shenmu coal, the catalyst and the co-catalyst evenly, and then crush the mixture until the particle size is no more than 200 mesh, so as to obtain the coal powder loaded with the catalyst; the catalyst is a nanometer iron-based catalyst, and the amount of the catalyst is 1 / 2 of the weight of the raw coal 3%; the co-catalyst is elemental sulfur, and the consumption of the co-catalyst is 5% of the raw coal weight; the nano-iron series catalyst is prepared by the following method: in the ferrous sulfate solution whose mass concentration is 10%, add A dispersant and a precipitating agent are stirred and reacted at room temperature for 3 hours to obtain a nano-iron catalyst with a colloidal particle size not greater than 20nm; the dispersant is sodium dodecylbenzenesulfonate, and the amount of the dispersant is ferrous sulfate solution 0.1% of the mass; the precipitating agent is urea, and the addition of the precipitating agent is 2% of the ferrous sulfate so...
Embodiment 2
[0035] Step 1. Mix the Shenmu coal, the catalyst and the co-catalyst evenly, and then crush the mixture until the particle size is no more than 200 mesh, so as to obtain the coal powder loaded with the catalyst; the catalyst is a nanometer iron-based catalyst, and the amount of the catalyst is 1 / 2 of the weight of the raw coal 1.5%; the cocatalyst is elemental sulfur, and the consumption of the cocatalyst is 3% of the raw coal weight; the nano-iron series catalyst is prepared by the following method: adding A dispersant and a precipitating agent are stirred and reacted at room temperature for 8 hours to obtain a nano-iron catalyst with a colloidal particle size not greater than 20nm; the dispersant is sodium dodecylbenzenesulfonate, and the amount of the dispersant is ferrous sulfate solution 0.2% of the mass; the precipitating agent is urea, and the addition of the precipitating agent is 4% of the ferrous sulfate solution quality;
