Petroleum Coke

Product Description

Petroleum Coke is a carbon-rich solid substance derived from petroleum refining and is a type of coke fuel. Petroleum coke is a type of coke obtained from the final cracking process in a unit called a coker. In short, petroleum coke is "the carbonized product of the high-boiling hydrocarbon fraction (heavy residue) obtained during petroleum processing." Petroleum coke, also known as petroleum coke, is a carbon-rich solid material produced during the refining of crude oil. It is usually a by-product of the refining process, produced when heavy crude oil is processed into gasoline, diesel and other refined products.

Specification

Calcination technology

The calcination process of petroleum coke is divided into three steps: drying, desliming and densification. The calcination process of coke is a function of time-temperature and takes place in an anoxic environment. The important control variables are the heating rate, the air addition rate and the final calcination temperature. To obtain the calcined carbonization properties required by the carbon and graphite industries, coke must withstand temperatures of 1150-1350 degrees Celsius or higher to achieve density and electrical conductivity. The final quality of calcined char is directly related to the specific characteristics and quality of the coke fed into the calciner. While calcination does not improve some of the quality limitations inherent in coke production, improper calcination may result in a loss of potential quality.

Application

In aluminium production,petroleum coke is essential in aluminium production. It is used in the manufacture of anodes, which are essential for the electrolysis process that separates aluminium from its oxides. In addition to this, petroleum coke is used in the production of titanium dioxide, as a component of brake pads and clutches and in the manufacture of lithium-ion batterie.
