1. ELECTRICITY RESOURCE

Coal is appointed as the primary supply of electricity in comparison to other electricity resources available. As much of the world lacks access to modern, clean energy, coal is still essential to alleviating worldwide energy poverty.

Coal-fired plants produce electricity by burning coal in a boiler to produce steam. The steam produced, under tremendous pressure, flows into a turbine, which spins a generator to create electricity. The steam is then cooled, condensed back into water and returned to the boiler to start the process over.

2. METAL PRODUCTION

The basic material to make steel is coke and metallurgical coal which is generally mine in Indonesia. 

Metallurgical (coking) coal is a key ingredient in steelmaking production- a non-ferrous metal known for its lightweight properties and widely used in cars, trains, and airplanes to reduce the weight of these vehicles and their energy consumption. 

Coal converted to coke is used to produce around 70% of the world’s steel. Coal is also widely used in the production of other metals including aluminium and copper.

3. CEMENT PRODUCTION

Cement is critical to the construction industry. To produce cement, energy is required. Coal is an important source of the energy needed. A high-temperature kiln, often fuelled by coal, heats the raw materials of calcium carbonate (generally in the form of limestone), silica, iron oxide and alumina to a partial melt at 1450°C, transforming them chemically and physically into a substance known as clinker. This grey pebble-like material comprises special compounds that give cement its binding properties. Clinker is mixed with gypsum and ground to a fine powder to make cement.

Coal combustion products (CCPs), such as Fly Ash also play an important role in cement manufacture and in the construction industry generally.

4. FUEL AND GAS PRODUCTION

Coal-derived fuels, as well as coal-based electricity, play a significant role in responding to the growing energy needs of the transport sector. Not only is coal an important raw material and source of primary energy for the manufacturing of materials used to build transport infrastructure, coal-based electricity has a role to play in supporting the electrification of the transport sector.

Liquid fuels from coal can provide a viable alternative to conventional oil products and can be used in the existing supply infrastructure. It is liquefied to make synthetic fuels similar to petroleum or diesel. 

5. CHEMICAL PRODUCTION

In modern gasifiers, coal is typically exposed to steam and carefully controlled amounts of air or oxygen under high temperatures and pressures. Under these conditions, molecules in coal break apart, initiating chemical reactions that typically produce synthesis gas (syngas), hydrogen, carbon monoxide and other gaseous compounds. 

The hydrogen can then be captured and stored. 20% of hydrogen production comes from coal-to-gas processes.

6. INDUSTRIAL NEED

Several chemical products can be produced from the by-products of coal in the coal-to-chemicals (CTC) industry. Refined coal tar is used in the manufacture of chemicals, such as creosote oil, naphthalene, phenol, and benzene. Ammonia gas recovered from coke ovens is used to manufacture ammonia salts, nitric acid and agricultural fertilisers. Thousands of different products have coal or coal by-products as components: soap, aspirins, solvents, dyes, plastics and fibres, such as rayon and nylon.

Our coal products are mainly coming from Indonesia and we offer four main calorific values. We can provide you until 300.000 Metric Tonne FOB Monthly.

And Indonesian coal is also famous for Steam Coal.

1. Lignite

Lignite is defined as non-agglomerating coal with a gross calorific value on moist ash free basis <4165 kcal/kg.

 GCV 3400 / 3600 

2. Sub-bituminous 

Coal is hard and brittle and black and shiny, moisture content is 20 – 40%, calorific value 4,000 kcal/kg to 5,800 kcal/kg

GCV 4.200 (Steam Coal)

3. Bituminous 

Coal is softer and shiny, moisture content is 8 -20% calorific value is 5,800 to 7,800 kcal/kg, crucible swelling number from 2 – 9+ possible for coking coals, volatile matter from 16% - 40%.

Coal can be categorized into different groups depending on the application. Thermal coal and coking coal are two such types of coal. The key difference between coking coal and thermal coal is that coking coal is mainly used to produce high quality coke, whereas thermal coke is important in producing electricity.

GCV 5.600 / 6.100 (Steam/Coking Coal)

GCV 7.200 / 7.500 (Coking Coal) 

4 Anthracite 

Coal is very shiny, repels moisture, calorific value 7,800 – 8,000 kcal/kg, no coking properties.

GCV 7.800 / 8.100 (Anthracite)
