Needle coke is
a premium grade petroleum coke,
which is used in manufacturing of graphite electrodes for arc
furnaces in steel industry. A good quality of needle
coke
is
hard and dense mass formed with a structure of carbon threads
or needles
oriented
in a single direction
-
There are
various grades of Needle coke depending on its properties/
specifications.
-
Production of Needle Coke requires specific feedstocks, coking
conditions and calcination conditions. The hardware employed is
similar
to that of Delayed Coker unit. Heavier streams available in the
refinery of lower sulfur content can be considered as the
feeddepending on the type of hydrocarbon
molecules present. The optimum set ofprocess conditions are
decided by thecharacteristics of the feedstock through
pilotplant experiments.
- Coal-based needle coke is
made from coal tar which appears during coke production
- Needle cokes are used as
a primary material for graphite electrodes in electric furnace.
Coal-based needle coke is produced from coal tar that appears
during coke production. Compared to petroleum-based needle coke,
coal-based needle coke has excellent physical properties, such
as low co-efficient of thermal expansion and low electric
resistance, along with less spalling and less breakage.
- Compared to the
conventional oil-based needle coke, the coal-based needle coke
has certain distinguishing characteristics, such as high heat
durability and world's lowest thermal expansion rate
- The rapid development of
the lithium-ion battery industry, the market for lithium battery
anode materials in China has grown significantly. A large number
of manufacturers have begun to use needle coke to produce anode
materials because of their low
cost, high gram capacity and overall stable performance. And the
annual consumption volume has been increasing year by year.
- But due to the late
industrialization of needle coke, China is 30 years later than
Japan and 60 years later than
the United States in the development of needle coke production
technology. There is a big gap in Needle Cokeproduction
technology and NC quality between imported needle coke and
domestically-made needle coke.
