petroleum coke and cadmium
Petroleum Coke - an overview ScienceDirect Topics
Petroleum coke is a chunky powdered carbon product derived from petroleum. If petroleum coke is heated to a high temperature, it may emit volatiles such as polynuclear aromatic hydrocarbons, which could be suspect carcinogens. ... cadmium, cobalt, etc.). The coke is first heated to drive off volatile matter and then ground and mixed with a coal ...

Petroleum coke - Wikipedia
Petroleum coke, abbreviated coke or petcoke, is a final carbon-rich solid material that derives from oil refining, and is one type of the group of fuels referred to as cokes.Petcoke is the coke that, in particular, derives from a final cracking process—a thermo-based chemical engineering process that splits long chain hydrocarbons of petroleum into shorter chains—that takes place in units ...

Sep 06, 2017 The effects of permanent poisons cannot be overstated. Blockages of the porosity, removal of active metal sites and agglomeration of the active metal by poisons often lead to an increase of in the relative rate of coke formation and carbon deposition. This can lead to severe process problems caused by poisoned petroleum refining catalysts.
