Petroleum Coke

What is Sponge Coke?

Sponge Coke is a type of petroleum coke produced through the deep thermal cracking process (Delayed Coking) in oil refineries. It is characterized by being:

  • Solid Carbon Product
  • Spongy/Porous Surface
  • Mainly used in metallurgical and electrical industries

Named "Sponge Coke" because its surface is porous and resembles a sponge under a microscope. This porosity aids in thermal reactions within industrial furnaces.

Technical Specifications of Sponge Coke

Property Typical Value
Fixed Carbon ≥ 85%
Sulfur 0.5% – 6.5% (depending on the source)
Ash ≤ 0.5%
Moisture ≤ 0.5%
Form Rough, irregular black pieces
True Density 2.1 – 2.3 g/cm³
Apparent density 0.7 – 0.9 g/cm³
Thermal Activity Highly Reactive

Industrial Uses of Sponge Coke

  • Aluminum Industry: Used in the production of carbon anodes in electrolytic cells
  • Iron and Alloy Industry: Carbon source in electric arc furnaces or cupola furnaces
  • Conversion to Calcined Coke: Used as an intermediate stage to improve purity and density
  • Energy and Industrial Fuel Industries: Used as an alternative solid fuel

Differences Between Types of Petroleum Coke

Type Form Use
Sponge Coke Spongy Porous Aluminum and Metal Industries
Needle Coke Granular/Needle Graphite Electrode Industry
Shot Coke Small Spheres Industrial Fuel (Low Quality)
Honeycomb Coke Regularly Porous Limited Use

Packaging and Export of Sponge Coke

Form Details
Bulk Shipping Via open ships or containers
Jumbo Bags 1 ton per bag
Barrels (Rare) Only in test shipments

What is Calcined Petroleum Coke (CPC)?

Calcined Petroleum Coke (CPC) is a high-purity solid carbon product obtained by heating raw petroleum coke (Green Petroleum Coke) to high temperatures (approximately 1200 – 1400°C) in specialized furnaces to remove volatile materials and improve physical and chemical properties.

Technical Specifications of Calcined Coke

Property Typical Value
Fixed Carbon ≥ 98.5%
Ash content ≤ 0.5%
Sulfur 0.5% – 3.0% (depending on the source)
Moisture ≤ 0.5%
True Density 2.03 – 2.10 g/cm³
Apparent density 0.80 – 0.95 g/cm³
Form Black pieces or granular powder
Thermal Activity High
Electrical conductivity Excellent (required in the electrode industry)

Industrial Uses of Calcined Coke

  • Aluminum Industry: Used in the production of carbon anodes for electrolytic cells
  • Industrial Graphite Industry: As a raw material for producing electrical graphite electrodes used in steel manufacturing
  • Iron and Alloy Industries: Pure carbon source for smelting and casting operations
  • Refractory Materials Industry: Used in furnace bricks and thermal pipes

Difference Between Green Coke and Calcined Coke

Item Green Coke (Raw) Calcined Coke (Calcined)
Carbon Content 80 – 85% ≥ 98.5%
Moisture Relatively High Almost Nonexistent
Volatile Materials 10 – 20% ≤ 0.5%
Direct use No Yes

Packaging of Calcined Coke

Form Use
Bulk Shipping Via tankers or containers
Jumbo Bags 1 ton per bag
Small Bags For small factories or testing
