Pet Coke Consulting for Buyers and Sellers of Petroleum Coke
challenges, global demand for Calcined Petroleum Coke (CPC) has finally bloomed, thanks to the steady demand for aluminium, one of the key CPC users. However, CPC prices declined ~25% during CY14‐ 16 owing to weak Green Petroleum Coke (GPC) prices. With growing use of light‐weight materials across key industries, we expect
Alcoa spokesman Jim Beck said by email the facility would start processing green petroleum coke in June and supply some of the company's aluminum smelters with calcined petcoke, ... At the time of the outage, the calciner produced about 250,000 mt/year of CPC for Alcoa's smelters, and sourced green coke from various oil refineries.
Ash ratio of calcined to green coke significantly varies from 10% loss to 46% gain, showing analytical - errors associated with low ash content of cokes studied (0.05-0.36 wt %). Sulfur content of petroleum cokes analyzed for this study varies in the range of 0.46 to 3.21 wt %.
strict in the tightening market. Trends in petroleum crude refining have also deteriorated the quality of Green Petroleum Coke (GPC). In addition to the quality of GPC, the anode grade CPC quality is also determined by the calcination process. Different calcination technologies have …
Thermal Desulfurization of Petroleum Coke for Anode Use
Calcined coke is a high quality carbon material produced by calcining green petroleum coke. Calcining is the process of heating green petroleum coke in a kiln to remove excess moisture, extract all remaining hydrocarbons and modify the crystalline structure of the coke, resulting in a denser more electrically conductive product.

Green petroleum coke is generated by delayed coking during the conversion of crude oil into liquid fuels such as gasoline and jet fuels. Green coke quality is derived mainly from the quality of crude oil that a refinery consumes.
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, ... Green coke with this low metal content is called anode-grade coke.
Calcined petroleum coke is the major raw material required for the production of carbon anodes used in the aluminium smelting process. Green coke (raw coke) is the product of the coker unit in a crude oil refinery and must possess sufficiently low metal content in order to be used as anode material.
Green coke with this low metals content is referred to as anode grade coke. The green coke with too high metals content will not be calcined and is used for burning. This green coke is called fuel grade coke. Approximately 23 percent of worldwide petroleum coke production is marked for calcined petroleum coke.

Anode-Grade Green Coke Availability. The supply of green petroleum coke is trending towards diminishing availability from U.S. Gulf Coast refineries and increasing trade movements of calciner feedstocks from different parts of the world (e.g. China, Kuwait) to the U.S. Gulf Coast.
Tesoro's Wilmington, California calciner is located near the Port of Long Beach and produces approximately 350,000 metric tons per year of calcined coke product. We also market the green coke production for the following sites: BP Toledo refinery and the BP Whiting refinery.

The feedstock anode grade green petroleum coke is a valuable by-product of the coke process in oil refineries available in different grades of quality Thermal processing of green petroleum coke to calcined petroleum coke by: removing associated moisture and volatile combustion matter
CPC is produced by heating or calcining green petroleum coke (GPC) at temperatures greater than 1200°C. The production of GPC has remained essentially the same since 1929 when the modern delayed coking process was born.
Petroleum coke calcining. Petroleum coke calcining is thermal treatment of green petroleum coke to beneficiate the material by removing moisture and volatile matter, while increasing density and decreasing electrical resistivity.
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).
