PROBLEM TO BE SOLVED: To provide a method of producing a chemical-carrying active carbon which can enhance the removal performance for bad smells, e.g. tobacco smell, a chemical-carrying active carbon and a filter using the active carbon.SOLUTION: A chemical-carrying carbon 30 can be obtained by a production method comprising an active carbon production step P1 of producing an active carbon 10 having a large number of mesopores and a chemical carrying process P2 of causing the active carbon 10 to carry a chemical 20 for removal of bad smell causative substances. The active carbon production step P1 comprises, as illustrate, a carbonization process S1 of carbonizing a raw material 1 of the active carbon and a gas activation process S2 of carrying out gas activation. As the raw material 1 of the active carbon, generally available are a wide variety of tree branches, including pruned apple tree branches and other branches of Rosaceae fruit trees, produced in large amounts during management of apple orchards, and branches of broad- and needle-leaved trees. |
