In bright, the mass ratio of the active carbon and maceration extract is preferably 1:(2.5~3).
In the present invention, maceration extract is imported into reaction kettle and carries out impregnation, specifically will be in normal pressure using pressure difference
Under the conditions of maceration extract import in reaction kettle, restore normal pressure in reaction kettle later, carry out impregnation.In the present invention, described
The time of impregnation is preferably 50~60min, the time of the impregnation imported in reaction kettle completely with maceration extract after open
Beginning timing；The impregnation carries out (i.e. true without additional heating, cooling or pressurization, pumping preferably under room temperature, condition of normal pressure
It is empty), more preferably carried out under 24~26 DEG C, condition of normal pressure；In the present invention, during the impregnation, preferably often
30~60s is stirred every 8~10min；The stirring is preferably realized by reaction kettle unitary rotation, specifically by reaction kettle entirety edge
Clockwise, with 15~20rpm rotational speed, it is advantageously implemented the homogeneous impregnation of maceration extract in this way, guarantees that maceration extract is uniform
Load on the activated carbon, and is that agitating paddle is arranged in reaction kettle in common process, is stirred easy presence by agitating paddle
Dead angle is not easy to realize the homogeneous impregnation of maceration extract, and product quality homogeneity is poor.The present invention is impregnated by pressure difference enhancement activated carbon
Mass transport process in facilitating impregnation liquid on active component uniform adsorption to the adsorption site of activated carbon surface, can improve active carbon
The performance of the load capacity of middle active component, gained carried active carbon is good.
After completing the impregnation, gained system is preferably separated by solid-liquid separation by the present invention, and gained load is had dipping
The active carbon of liquid is dried, and obtains carried active carbon.The present invention does not have the mode of the separation of solid and liquid special limit
It is fixed, it is specific as filtered using solid-liquid separation method well known to those skilled in the art.In the present invention, the drying
Temperature is preferably 100~110 DEG C；The present invention can enhance activity by the dry solvent for removing maceration extract in active carbon
