Compared to needle coke, honeyco coke has a lower coefficient of thermal expansion and a lower electrical conductivity. Production Process of Petcoke Petroleum coke can either be fuel grade (high in sulfur and metals) or anode grade (low in sulfur and metals).
Is petroleum coke hazardous - Answers
According to the MSDS petroleum coke is considered hazardous under 29 CFR 1910.1200 (Hazard Communiion). For a more in depth analysis, see below: The following is a
Calcined Petroleum Coke
Calcined Petroleum Coke is a critical ingredient in the production of aluminum. It is created by placing high quality raw "green" petroleum coke into rotary kilns, where it is heated to temperatures between 1200 to 1350 degrees C (2192 to 2460 F).

Corus coke 5 - 10 mm and Corus coke 15 - 20 mm was used, respectively. By comparison, the bulk resistivity of the dry coke bed at 1600 C was measured as 4.2 mW·m and 3.9 mW·m, for the Corus coke 5 - 10 mm and 15 - 20 mm size fractions, respectively
Calcined petroleum coke (CPC) is created from green petroleum coke (GPC), a by-product of refining crude oil. While CPC can be created using a nuer of processes -- including rotary kiln, hearth and vertical shaft technologies -- the high-temperature conversion from green coke to calcined coke alters the material in key three ways:

Romantic Ralings: What is Needle Coke?
Needle coke is made from petroleum, so all needle coke IS petcoke. However, NOT all petcoke is needle coke! Just about every gasoline refinery has a coker unit that makes a form of petcoke. Most of that is sponge coke, or shot coke, of some other form of
Delayed coker - Wikipedia
A delayed coker is a type of coker whose process consists of heating a residual oil feed to its thermal cracking temperature in a furnace with multiple parallel passes. This cracks the heavy, long chain hydrocarbon molecules of the residual oil into coker gas oil and petroleum coke. Delayed coking is one of the unit processes used in
