On August 4, 2021, Maoming Petrochemical's 100,000 tons/year high-end carbon material complex successfully produced qualified needle coke (green coke) products
.
Needle coke has a series of advantages such as low thermal expansion coefficient, low sulfur, low ash, low metal content and easy graphitization.
It is mainly used as graphite electrode and lithium battery anode material, and is widely used in defense, metallurgy and new energy industries
.
Needle coke has a series of advantages such as low thermal expansion coefficient, low sulfur, low ash, low metal content and easy graphitization.
Guided by the industrial pattern of "one base, two wings and three new innovations", Sinopec seizes development opportunities, makes use of its mature technology research and development advantages and abundant catalytic slurry resources, and is committed to developing the "technology for producing high-quality needle coke from inferior oil slurry", and builds Put into production of industrial application devices, and further promote the development of high-end carbon materials
.
The device uses catalytic oil slurry as raw material to produce high-quality needle coke products, and by-products dry gas, wax oil, diesel oil, gasoline,
etc.
For the first time, the device adopts a sequential control system for decoking operation, which eliminates manual accidental operation and has good safety performance; high production automation can greatly improve labor efficiency; decoking, water treatment, dust removal and other links are all airtight, which can effectively reduce Exhaust emissions, to achieve green production
.
The installation started construction in November 2019
.
After the plant is put into operation, the structure of Maoming Petrochemical's refining products has been further optimized, which is of exemplary significance for improving the technical level of needle coke production in China and expanding production, promoting the processing and transformation of domestic new energy battery raw materials, and the development of the electric furnace steelmaking industry
.
