Product Details
1)Product introduction
Graphitized petroleum coke is also called graphitized recarburizer, artificial graphite, graphite powder, synthetic graphite and so on. The high carbon, low sulfur, low nitrogen graphitized petroleum coke produced by Xintan is based on calcined petroleum coke as raw material, after 3000 degrees of high temperature graphitization treatment, and then through crushing, screening, packaging to complete. According to customer requirements, graphitized petroleum coke products with different particle sizes of 0-50mm can be provided, and the conventional particle size is 1-5mm/0.5-5mm/2-5mm/0.2-1mm. Graphitized petroleum coke is widely used in gray and high-end ductile iron casting, steel production, automotive and brake pad production, cylinder liner and camshaft manufacturing. As the preferred material for high-end users in the casting industry, "Xintan" recarburizer has excellent characteristics such as high carbon content, high purity, good absorption rate and stable quality.

3)Product advantages
A)High carbon content. High degree of graphitization, excellent purity, carbon content of graphitized petroleum coke is more than 98.5%, used in iron and steel smelting, casting and forging processes, can improve the carbon content of castings, improve the mechanical properties of castings, improve hardness and wear resistance.
B)Low sulfur content. The sulfur content of high-quality graphitized petroleum coke recarburizer can be as low as 0.01-0.05%. If the sulfur content in the recarburizer is high, the strength of the steel will be greatly reduced, resulting in brittleness and cracking of the steel.
C)Low nitrogen content. Nitrogen content is stably controlled between 80PPM- 250PPM, is the most ideal auxiliary material for steel strand.
D)High absorption rate. The recarburizer has uniform particle size, large porosity and fast absorption rate. The general absorption rate is above 95%, and the absorption rate is better than that of similar recarburizers.
4)Applications
Graphitized petroleum coke/recarburizer/graphite powder/artificial graphite/ synthetic graphite is widely used in the following fields:
- Foundry: gray cast iron and high end ductile cast iron casting
- Steel plant: steel production
- Metallurgical plant
- Automotive and auto parts manufacturers: brake pads, cylinder liners, camshafts, etc
- Deep processing can be made into lithium ion battery cathode materials, graphene, etc
- Oil drilling platforms: used as bridging agents.
5)Remark:
Keep dry when storing to avoid moisture.

CO removal catalyst (Ceramic honeycomb)
CO removal catalyst (Honeycomb) uses cordierite honeycomb ceramic as a carrier and is a highly active catalyst prepared from a variety of rare earth metals. The CO removal catalyst (Honeycomb) produced by Hunan Xintan has the characteristics of high structural strength, strong surface coating adhesion, and is not easy to fall off. This catalyst can not only be used to treat carbon monoxide in flue gas, but also has high catalytic performance in chlorine-containing working conditions, and can be used for the treatment of chlorine-containing organic waste gas, and is widely used in the treatment ofsteel flue gas, lime kiln flue gas, waste incineration smoke and other smoke.
CO removal catalyst (Pt and Pd)
CO removal catalyst (pellet with Pt and Pd) is a precious metal palladium catalyst with alumina as a carrier. The carbon monoxide precious metal catalyst produced by Hunan Xintan is dark brown spherical particles with a diameter of 3-5mm, which is mainly used to remove H2 and CO at 20℃~300℃. The catalyst can convert CO to CO2 and H2 to H2O. It does not contain MnO2, CuO or S, so it can be safely used for CO purification in CO2. CO removal catalyst (pellet with Pt and Pd) have the characteristics of high catalytic efficiency, stable performance, safety, no energy consumption and long service life, and are widely used in the food industry.
CuO catalyst (for removing oxygen from Nitrogen)
CuO catalyst (for removing oxygen from Nitrogen) developed by Hunan Xintan is made of a high proportion of copper oxide (CuO) and inert metal oxides. It is a black cylindrical particle with a diameter of 5mm and a length of 5mm. The catalyst has the characteristics of high active component content, high packing density, low cost and long service life. It is a catalyst used to remove oxygen from nitrogen or inert gases such as helium and argon, which can efficiently convert oxygen to CuO without the need for additional energy. It does not contain any dangerous substances. The catalyst is widely used in gas treatment because of its high efficiency. The catalytic deoxidation reaction equation is as follows: CuO+H2=Cu+H2O 2Cu+O2=2CuO
