Application Details
♦ Suitable Products
In the chemical industry, calcined petroleum coke is the core raw material, while all-graphite petroleum coke and semi-graphite petroleum coke are used in small quantities only in specific niche applications.
♦ Application Scenarios
1. Calcined petroleum coke (primary raw material, applicable to multiple scenarios)
• Silicon carbide (SiC) production
Silicon carbide is produced by reacting silica sand (SiO₂) with silica sand as a carbon source in a high-temperature electric arc furnace. Silicon carbide is a key raw material for abrasives, refractory materials, and semiconductor devices. This process requires medium-to-high purity calcined petroleum coke to prevent impurities from affecting the silicon carbide crystal structure.
Common specifications for this application：
► Fixed carbon ≥ 96% ► Sulfur ≤ 0.5%
► Ash content ≤ 1.0% ► Volatile matter ≤0.5%
• Carbon disulfide (CS₂) synthesis
Carbon disulfide is prepared by reacting calcined petroleum coke with sulfur at high temperatures. Carbon disulfide is a basic raw material for rubber vulcanizing agents and organic solvents.
This process requires low-sulfur calcined petroleum coke to prevent excessive sulfur content in the raw material from reducing product purity.
Common specifications for this application：
► Fixed carbon ≥ 96% ► Sulfur ≤ 0.3%
► Ash content ≤ 1.0% ► Volatile matter ≤0.5%
• Chemical kiln fuel
As a low-volatile, high-calorific-value fuel, it is used in chemical rotary kilns and roasting furnaces to replace some coal or heavy oil, reducing sulfur and dust emissions in flue gas. It is suitable for chemical heating processes with high fuel purity requirements.
Common specifications for this application：
► Fixed carbon ≥ 92% ► Sulfur ≤ 1.0%
► Ash content ≤ 2.0% ► Volatile matter ≤1.0%
• Carbon-based catalyst support
High-purity calcined petroleum coke, after being crushed and activated, can be used as a catalyst support for organic synthesis reactions (such as hydrogenation and dehydrogenation reactions), utilizing its porous structure to support the active components of the catalyst.
Common specifications for this application：
► Fixed carbon ≥ 98% ► Sulfur ≤ 0.05%
► Ash content ≤ 0.3% ► Specific surface area ≥500m²/g
2. All-graphite petroleum coke (niche raw material, high-end niche application)
• High-end Chemical Reactor Liners
Utilizing their high graphitization and resistance to acid and alkali corrosion, graphite linings or pipe fittings are manufactured for use in chemical reaction equipment involving strong acids, strong alkalis, and high temperatures and pressures (such as hydrochloric acid synthesis furnaces and hydrogen fluoride reactors), replacing metal linings and extending equipment lifespan.
• Conductive Fillers
As conductive additives, they are added to polymer materials (such as plastics and rubber) to prepare antistatic or conductive chemical products (such as antistatic coatings for chemical pipelines and conductive seals), relying on their low resistivity and good dispersibility.
• Key Technical Parameters
► Fixed carbon ≥ 99% ► Sulfur ≤ 0.03%
► Ash content ≤ 0.3% ► Volatile matter ≤0.3%
► Graphitization ≥95% ► Resistivity ≤15μΩ・m
3. Semi-graphite petroleum coke (auxiliary raw material, low-cost application)
• Production of Ordinary Chemical Carbon Bricks
Used as a filler raw material and mixed with a binder, these are pressed and fired to produce carbon bricks for chemical kilns or storage tanks. They are used for corrosion protection and insulation layers, with lower performance requirements and a focus on cost advantage.
• Low-End Adsorption Materials
After simple crushing and activation, these are used for primary adsorption treatment of industrial wastewater and exhaust gases (such as adsorbing heavy metal ions in water and organic pollutants in exhaust gases). Suitable for applications where high adsorption efficiency is not required.
• Key Technical Parameters
► Fixed carbon ≥ 95% ► Sulfur ≤ 0.3%, ash content ≤ 2.0%
► Volatile matter ≤ 1.0% ► Graphitization degree ≥ 50%
