The hardness number is the most popular test method, followed by the abrasion number. The hardness number (DSTM 20) gauges how well AC's external integrity holds up to wear along the edges and breaking of small points. After shaking granules under specific circumstances, it is stated as a percentage of loss on a specific …
It tends to be more isotropic, or fine granular in texture and is hard with a low porosity and high density which makes it difficult to crush. Coking severity decreases from bottom to top in the drum so bottom coke is …
