Catalytic slurry production of needle coke technology realizes industrialization

Product indicators meet the requirements of needle coke for ultra-high power graphite electrodes

Sinochem News.
com News from Sinopec Jinling Petrochemical Branch's high-end graphite equipment produced needle coke products recently completed the preliminary application performance evaluation
.

At the beginning of 2019, the technology for producing high-quality needle coke from THTD catalytic oil slurry of Dalian Research Institute passed the technical feasibility demonstration organized by the Science and Technology Department of Sinopec Group; at the end of 2020, the first set of 150,000 tons/year high-end graphite material equipment constructed with THTD technology was established in Jinling, Sinopec.
Petrochemical branch of China Commodity; In January 2021, the plant will be put into operation and continuous and stable production will be realized
.

The project team leader Chu Renqing said that in order to meet the different performance requirements of the downstream graphite electrode companies for needle coke, the thermal expansion coefficient (CTE value) of needle coke products produced by Jinling Petrochemical’s high-end graphite plant is 1.
0~1.
3×10-6 It can be adjusted between /℃, which can meet the requirements of various indexes of needle coke products for graphite electrodes required by GB/T37308-2019
.

It is understood that needle coke is an irreplaceable high-temperature conductive heating material for electric arc furnace steelmaking and a high-quality raw material for preparing high-end lithium battery anode materials.
It has a wide range of applications, but at present, China's high-quality oil-based needle coke relies on imports
.

Aiming at the unstable production process of traditional needle coke production with variable temperature, variable pressure, and variable raw materials, the THTD catalytic slurry with independent intellectual property rights developed by Dalian Research Institute produces high-quality needle coke technology, while achieving the production of high-quality needle coke products.
, Improve the stability of the operation of industrial equipment, and ensure the stability of the quality of high-end needle coke products
.

　　The start of production of the high-end graphite device of the Jinling Petrochemical Branch has achieved a breakthrough in Sinopec's continuous and stable production of high-end needle coke products, which is of great significance to the promotion of the high-end transformation and upgrading of China's refining business
