Analytics for Recovery and Reuse of Solid Wastes from Refineries
Energies, 2022 Heavy fractions of petroleum have for long time been bypassed in favour of lighter fractions. Nowadays, in the framework of the “circular economy”, there is a growing interest in residual petroleum heavy fractions.

Toxicological Assessment of Green Petroleum Coke [PDF]
International Journal of Toxicology, 2013 Green petroleum coke is primarily inorganic carbon with some entrained volatile hydrocarbon material. As part of the petroleum industry response to the high production volume challenge program, the potential for reproductive effects was assessed in a subchronic toxicity/reproductive toxicity screening test in rats (OECD 421). The repeated-dose portion

Coke Decomposition Kinetic Model of Spent Hydrodesulfurization Catalysts [PDF]
Journal of Applied Sciences and NanotechnologyRecycling residue hydrodesulfurization (HDS) catalysts is essential due to frequent deactivation. Petroleum coke's high ignition temperature and complex combustion behavior stem from its graphite-like structure and low volatile matter.
