Embodiment Construction
[0019] The invention provides a method for preparing activated carbon with low ash and high specific surface area, comprising S1, selecting coal with an ash content lower than 8% and pulverizing it to below 200 mesh; S2, selecting husk carbonized material, crushing and pulverizing it to below 200 mesh; S3, The coal in steps S1 and S2, the carbonized material of fruit shells and the binder are premixed according to the mass ratio of 100:10-100:20-60 to form a premix; S4, the premix is mixed at 45-120 Mix and knead evenly under the condition of ℃, and extrude under the condition of 10-20MPa, the diameter is 4mm-12mm, and dry; ℃, the carbonization time is 0.5-5h; S6, after strong carbonization, the material is activated with water vapor at 800-1100℃ for 0.5-5h to obtain low ash and high specific surface area activated carbon.
[0020] The activated carbon prepared according to the method for preparing activated carbon with low ash and high specific surface area of the present...
