— Petroleum coke and petcoke are all designations that belong to a by-product of the oil refining process. It is a carbon-rich solid. Petroleum coke can be used for various industrial and commercial applications, not to mention as an energy source. Given the importance of these uses, petroleum coke is an essential part of the global energy …
Physical-Chemical Properties: Because petroleum coke (both green coke and calcined coke) is the substance remaining from treating heavy petroleum feedstocks with high temperature and pressure, many of the physical-chemical properties are not meaningful at ambient environmental conditions. At ambient
Petroleum coke, or petcoke, is a product produced from all types of oil (light/heavy crudes) during the oil refining process. Many different products are extracted from a barrel of crude oil in addition to gasoline, diesel and jet fuels. Petroleum coke just one of the many. Petroleum coke is not a new product and has been produced since the 1930s.
— Petroleum coke, also known as petcoke, is a byproduct of the oil refining process. It is made from heavy crude oil that has been distilled to remove lighter …
— Carbon anodes used in Hall–Héroult electrolysis cells are involved in both electrical and chemical processes of the cell. Electrical resistivity of anodes depends on electrical properties of its constituents, of which carbon coke aggregates are the most prevalent. Electrical resistivity of coke aggregates is usually characterized according to …
Petroleum coke becomes the preferred substitute when the discount to coal is higher than 15% in the European region. The outlook for Q1 of FY22 is likely to reflect the market sentiments of North America which is the main source of Europe's imports for petroleum coke. ... Physical and chemical properties of pet coke are dependent on quality ...
The said Green or Raw Petroleum Coke calcined at a temperature 12000 centigrade to 13000 centigrade is known as Calcined Petroleum Coke. Calcined Petroleum Coke is extensively used for melting purpose of Alumina in Aluminium industry, as a carbon raiser while making Special High Carbon Steel in Foundries, as a conductive backfill in ground ...
Generally, the physical properties of petroleum coke depend on the composition and characteristics of the feedstock [11]. Works have been performed to obtain the thermal properties of petroleum coke [7,11,12]. The thermo-physical properties of petroleum coke vary in different calcining temperature, especially at different heating rates.
— The properties of the petroleum cokes were analyzed according to the methods in SH/T 0313-1992. ... m was the quality of the coke and v was the volume of the coke. In Eq., when the mass of the sample is fixed, different sample volume leads to different real density. As the calcination temperature increased, there is big difference of …

Volatile matter (VM) analysis of green petroleum coke is an important measurement for determining the calcination behavior and properties of calcined coke. Green cokes with high VM (>12%) are more difficult to calcine and result in a higher porosity and lower bulk...
— Petroleum coke is a granular, columnar or needle-like carbon substance composed of tiny graphite crystals, including green coke, calcined coke and needle-like coke. 1–3 It is used as a raw material for various industries, including prebaked anodes, industrial silicon, negative materials for new energy lithium batteries and so on. 4–6 The ...
Petcoke is a co-product of several processes used during petroleum refining to upgrade "residuum" into gasoline and middle distillate-range fuels. Residuum (or resid) is the substance that remains after refineries initially distill heavy crude oils.
petroleum coke The solid carbonaceous material produced from a coker after cracking and distillation from petroleum refining operations. This coke is also termed "green" coke or "fuel grade" coke. 3.3 roadway Any road used for repeated travel by car, truck, or off-road mobile heavy equipment but does not mean any part of a
— 1. Introduction Petroleum coke is a granular, columnar or needle-like carbon substance composed of tiny graphite crystals, including green coke, calcined coke and needle-like coke. 1–3 It is used as a raw material for various industries, including prebaked anodes, industrial silicon, negative materials for new energy lithium batteries and so on. …
The calcined petroleum cokes are used in production of aluminum anode-grade, graphite electrode, needle-grade, titanium dioxide pigments. Petroleum coke (green and calcined) is produced by the high pressure thermal decomposition of heavy petroleum process streams and residues. Green coke undergoes additional thermal processing to produce calcined …
