  • the activation treatment in the preparation of the samples of Examples 1 to 4 described below is also the same as that of the flow activation furnace used for the activation treatment of the above-mentioned commercially available granular coconut shell activated carbon "Kuraray Coal (registered trademark) GGS-N28 / 70". I went with the equipment.
  • Example of Example 1 The coarsely crushed coconut shell charcoal, which is a raw material, was subjected to an activation treatment by a flow activation furnace, and the obtained granular coconut shell activated carbon was used as a sample.
  • the activation treatment is a more severe activation treatment than the activation treatment applied to the commercially available granular coconut shell activated carbon in order to make the acetone adsorption performance of the obtained granular coconut shell activated carbon about 28 mass%. Adjustments were mainly made to extend the activation treatment time.
  • Example of Example 2 The coarsely crushed coconut shell charcoal, which is a raw material, was subjected to an activation treatment by a flow activation furnace, and the obtained granular coconut shell activated carbon was used as a sample.
  • the activation treatment mainly extends the activation treatment time so that the activated adsorption treatment of the obtained granular coconut shell activated carbon is about 37 mass fraction% so that the activation treatment is more severe than the activation treatment of Example 1. Adjustments were made.
  • Sample of Example 3 The coarsely crushed coconut shell charcoal, which is a raw material, was subjected to an activation treatment by a flow activation furnace, and the obtained granular coconut shell activated carbon was used as a sample.
  • the activation treatment mainly extends the activation treatment time so that the activation treatment is more severe than the activation treatment of Example 2 in order to make the acetone adsorption performance of the obtained granular coconut shell activated carbon about 40 mass%. Adjustments were made.
  • Example of Example 4 The coarsely crushed coconut shell charcoal, which is a raw material, was subjected to an activation treatment by a flow activation furnace, and the obtained granular coconut shell activated carbon was used as a sample.
  • the conditions for the activation treatment are such that the acetone adsorption performance of the obtained granular coconut shell activated carbon is set to a value larger than that in Example 3 (if possible, about 45% by mass), compared to the activation treatment in Example 3.
  • adjustments were mainly made to extend the activation treatment time.
  • Example of Comparative Example 4 The coarsely crushed coconut shell charcoal as a raw material was subjected to activation treatment by a rotary kiln, and the obtained granular coconut shell activated carbon was used as a sample. The conditions for the activation treatment were adjusted so that the resulting granular coconut shell activated carbon had an acetone adsorption performance similar to that of Comparative Example 3.
  • Acetone adsorption performance measurement> The acetone adsorption performance of the granular activated carbon was measured according to JIS K 1474. Granular activated carbon is as described in ⁇ 2. The granular coconut shell activated carbon of the same lot except for Comparative Example 4 was used among those used in the measurement of lightness L * value, chromaticity a * value and chromaticity b * value, and calculation of color difference ⁇ E value>. Table 2 shows the measurement results of the acetone adsorption performance of the granular coconut shell activated carbons of Comparative Examples 1 to 3 and Examples 1 to 4.
  • the visual observation was performed by observing the enclosed granular coconut shell activated carbon through a transparent glass bottle, and then directly observing the activated carbon from the glass bottle on a desk. Based on the results of the above-mentioned visual observations, the panelist judged whether or not two different samples could be discriminated by brute force of the seven samples, and recorded the discriminable sample combinations. The records of the combinations of the identifiable samples are tabulated by visual observation by the panelists, and the results expressed in percentage are shown in Table 3.
  • the numerical values in Table 3 are% of the number of panelists judged to be distinguishable by visual observation.
  • Comparative Examples 1 to 3 could not be distinguished from each other. It was also found that Examples 2 to 4 could not be distinguished from each other.
  • Example 1 50% or more of the panelists were judged to be distinguishable from Comparative Examples 1 to 3, while less than 50% of panelists were judged to be distinguishable from Examples 2 to 4, so that According to the observation, it can be said that the granular coconut shell activated carbon is closer to the particles of Examples 2 to 4. Therefore, when the granular coconut shell activated carbon of Comparative Examples 1 to 3 is an illegal product and the granular coconut shell activated carbon of Examples 1 to 4 is an authentic product, both can be visually identified, and thus the authenticity judgment of smoking articles can be filtered. It can be carried out with the granular activated carbon contained in the part.
