Conventionally, porous carbon molded products have generally been produced by heat-treating coke and binder pitch as raw materials. The bonding force between the particles constituting the material is weak, the bending strength is reduced, and the bending strength is at most 20~s o
Only about kg/crl can be obtained. Also,
Since the pores of a carbon molded article are irregular in shape and distribution, it is necessary to arrange the pores to have a uniform diameter when used as a filtration or diffusion filter, for example.

The contact between the hydrochloric acid-formaldehyde-containing aqueous solution and the phenol is such that the phenol is added to the aqueous solution to first form a transparent solution, then to form a white turbidity, and then to form at least a pink granular or powdery solid. It is preferable to carry out the process in such a way that a solid substance is formed, since a granular or powdery solid substance with a small average particle size can be obtained. At this time, before adding phenols to the aqueous solution to generate cloudiness,
The aqueous solution is stirred so that the added phenols and the aqueous solution form a transparent solution as uniform as possible, and
It is preferable not to apply mechanical shearing force, such as stirring, to the reaction solution from the time when cloudiness occurs until a pale pink solid is formed.
