为了阐明煤抽提物（HyperCoal）对焦炭强度的影响机理，将煤抽提物模型化合物8种多环芳烃添加到混煤中。大环芳烃（晕苯、二萘嵌苯、萘并[2，3-a]芘）的加入大大提高了焦炭的强度，而三环芳烃（蒽、菲）的加入对焦炭的强度没有显著影响。由于大的多环芳烃化合物对煤分子具有更大的亲和力，因此它们与煤颗粒共融合。结果，抑制了焦化期间大孔的形成，导致焦炭强度增加。
Eight polyaromatic hydrocarbons that are model compounds of coal extract were added to coal blends to clarify the mechanism of the effects of coal extract (HyperCoal) on coke strength. Addition of large aromatic-ring compounds (coronene, perylene, naphtho[2,3-a]pyrene) greatly enhanced coke strength, whereas three-ring aromatics (anthracene, phenanthrene) had no significant effect on coke strength. Because large polyaromatic compounds have greater affinity for coal molecules, they co-fused with the coal particles. As a result, formation of large pores during coking was suppressed, leading to increased coke strength.
