5 Surprising Uses for Coal Besides Power Generation
When we think of coal, the first thing that comes to mind is power generation. Coal has been used for centuries as a source of energy to generate electricity, but did you know that it has many other uses as well? In this blog post, we will explore five surprising ways in which coal is used beyond power generation.
1. Activated Carbon
Activated carbon, also known as activated charcoal, is a highly porous form of carbon that is produced by heating coal to a high temperature with a gas such as steam. Activated carbon has a wide range of uses, including water filtration, air purification, and soil remediation. It is also used in the production of medicines, cosmetics, and food additives.
2. Carbon Fiber
Carbon fiber is a lightweight and strong material that is used in a variety of products, from aerospace to sports equipment. It is made by heating coal tar or petroleum pitch at high temperatures to produce fibers, which are then woven into a fabric. Carbon fiber is known for its exceptional strength-to-weight ratio and has replaced traditional materials such as steel and aluminum in many applications.
3. Silicon Metal
Silicon metal is an important component in the production of electronics, solar panels, and many other products. It is made by heating coal and silica together in an electric arc furnace to produce a material that is over 95% pure silicon. Silicon metal is used in the production of semiconductors, which form the basis of modern electronics.
4. Carbon Black
Carbon black is a fine powder that is made by burning coal or oil in a controlled environment. It is used as a pigment in inks, paints, and plastics, as well as a reinforcing agent in tires and other rubber products. Carbon black is known for its ability to absorb ultraviolet light, making it useful in sunscreens and other protective coatings.
5. Coal Tar
Coal tar is a viscous liquid that is produced by heating coal to high temperatures in the absence of air. It is a byproduct of coke production, which is used in the production of steel. Coal tar is used in a variety of industrial applications, including the production of pavement sealants, roofing materials, and pesticides. It is also used in the production of medicines, including treatments for psoriasis and eczema.
In conclusion, coal has many surprising uses beyond power generation. From activated carbon to carbon fiber, silicon metal to carbon black, and coal tar, coal has proven to be a versatile material with a wide range of applications. As technology continues to advance, it will be interesting to see what other surprising uses for coal are discovered.
