ated with HGI (hardness). Although petcoke produced from different refineries has its own characteristics, a general rule that applies to most petcokes is that as the volatile content falls, the material gets harder and the HGI test result is lower. As HGI is an important test for most pet-coke consumers, a poor sample affects the HGI result.

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 ...

Analysis and Characterization of High-Volatile Petroleum Coke

an important indication of coke quality and properties. Green coke volatility levels can be qualitatively related to calcined coke quality [11]. Low-volatile coke is a more concentrated sulphur-bearing coke. Cokes of low volatile matter content are in general easier to remove from the coke …

Petroleum Coke - an overview | ScienceDirect Topics

A. A Boateng, in Rotary Kilns (Second Edition), 2016. Abstract. Petroleum coke is a by-product of the coker process in the oil industry. In its raw form, it is also called "green coke" or green petroleum coke. Calcined petroleum coke is an important industrial commodity that links the oil and the metallurgical industries as it provides a source of carbon for various metallurgical ...

controlled to insure adequate hardness of the green coke produced by the Coker. An "optimal" reside yield for a refiner more concerned about downstream catalytic units may not necessarily be optimal for eventual calcined coke properties [1]. Petroleum cokes are produced at refineries using three

PET Plastic (Polyethylene Terephthalate): Uses, Properties ...

Recycled PET can be converted to fibers, fabrics, sheets for packaging and manufacturing automotive parts. Chemically, Polyethylene terephthalate is very much similar to Polybutylene Terephthalate. PET is highly flexible, colorless and semi-crystalline resin in its natural state.Depending upon how it is processed, it can be semi-rigid to rigid.

samples A and C. Therefore, coke A and C can be used in production of anodes for the aluminum or as carburizer in the foundries. Due to the high content of the ash and metallic content, coke B, can be recommended as burning agent. Key words: aluminum anode-grade, petroleum coke, moisture, volatile carbon matter, metals. 1.

Blast Furnace Coke Hardness - Mineral Processing & Metallurgy

Changes in coke hardness affect the working of the blast furnace, for soft coke is an obstacle to proper furnace operation. Soft coke is due to a low hydrogen-oxygen ratio in the coal charged; increasing this ratio increases the hardness of the coke. The best means of determining the hardness of coke is the combined tumbler and ball-mill.
