Abstract
•Oil shale catalytic pyrolysis decreased oil yield and increased AHs production.•ZSM-5 (25) and ZSM-5 (38) are suitable catalysts for AHs formation.•ZSM-5 (25) catalysis produced more PAHs and fewer MAHs.•Cracking of aliphatic hydrocarbons followed by aromatization is the main pathway.•Regulation and matching of cracking and aromatization is important to produce AHs.
