Embodiment 1
[0027] A preparation method of metal silicon reducing agent, it comprises the steps:
[0028] ①. Preparation of ultra-low ash coal: first make the pretreatment tank and coal slurry, then add the coal slurry into the pretreatment tank, and at the same time continuously inject 10% six Sodium metaphosphate solution, then put the obtained coal slurry device in the treatment cylinder, and add the mixed solution of heavy octanol and kerosene with a mass ratio of 1:9 to the water line with a diameter of less than 1mm, and then send the obtained liquid into the flotation machine In the process, the floating material is added to the filter press to obtain ultra-low ash coal after pressure filtration;
[0029] ②, pulping, with the mass fraction being 20 parts of cassava flour, 75 parts of water and 3 parts of NaOH, react in the reactor to prepare slurry, and control the temperature in the reactor to be 60°C;
[0030] ③, mixing materials, mixing biomass materials, sawdust, pig manure ex...
