[0048] The preparation method is as follows: ①Heating, evaporating and concentrating the black liquor until the solid content is greater than 20%, and keeping the temperature at 80-90°C; ②Heating the furfural resin to 80-90°C for standby; Mix at 60-100°C, stir evenly, slowly add the rest of the ingredients during this period, stir while adding, control the feeding time at 1.5-2 hours, and react for 2.5-3 hours.
Embodiment 3
[0050] A binder for activated carbon molding prepared from papermaking black liquor, comprising the following components by weight percentage:
[0051] Black Liquor Concentrate 65%
[0052] Bitumen and coal tar mixture (bitumen: coal tar = 2:8) 15%
[0053] Starch 7%
[0054] Furfural residue 10%
[0055] Surfactant 3%;
[0056] The preparation method is as follows: ①Concentrate the black liquor by heating, evaporating and concentrating until the solid content is greater than 20%, and keep the temperature at 80-90°C; ②Stir the pitch and coal tar evenly at 80-90°C according to the ratio; The above-mentioned ratio is mixed at 60-100°C, and stirred evenly. During this period, the remaining ingredients are slowly added, and stirred while adding. The addition time is controlled at 2-2.5 hours, and the reaction is 3-3.5 hours.
