Toxicological assessment of green petroleum coke.
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 of the study provided evidence for dust acc...
متن کاملActivated Petroleum Coke for Natural Gas Storage
Carvões ativados (CA) são caracterizados por elevadas áreas superficiais específicas e elevados volumes de poros. Os principais processos de obtenção destes materiais consistem na ativação de precursores com elevado teor de carbono, como por exemplo, o coque de petróleo (CP). Neste trabalho CP foi ativado quimicamente com hidróxido de potássio (KOH). O produto foi caracterizado por meio de adso...
متن کاملsuppression of coke formation in thermal cracking by coke inhibitors
the main purpose of this research was to:1.develop a coking model for thermal cracking of naphtha.2.study coke inhibition methods using different coke inhibitors.developing a coking model in naphtha cracking reactors requires a suitable model of the thermal cracking reactor based on a reliable kinetic model.to obtain reliable results all these models shall be solved simultaneously.for this pu...
15 صفحه اولSimulation of Char Dust Combustion inside a Pyroscrubber Downstream of a Petroleum Coke Calcining Kiln
A pyroscrubber is a furnace used in the petroleum coke calcining industry to recover energy from the carbonaceous contents, including char dust and hydrocarbon volatiles of the exhaust gas from the calcination kiln. The combusted hot gases are used to generate steam and produce electricity, so it is important to optimize the pyroscrubber performance to produce high-grade combusted gases to gene...
متن کاملOzonation of naphthalenetrisulphonic acid in the presence of activated carbons prepared from petroleum coke
The objective of this work was to analyze the activity of petroleum coke and of activated carbons prepared from this material in the ozonation of aromatic contaminants of low biodegradability. 1,3,6-Naphthalenetrisulphonic acid (NTS) was selected as model compound for the study. The presence of the original coke during 1,3,6-naphthalenetrisulphonic acid ozonation produced a slight increase in t...
