The History of coal coconut!

People have been making charcoal since about 4000 BC in China and West Asia. When naturally occurring ores of copper, zinc, and tin oxides are heated with charcoal, the carbon strips away the oxygen, leaving the pure metal behind. Alloying copper with tin forms bronze. The Bronze Age was followed by the Iron Age, characterized by the smelting of iron from iron oxide with charcoal. That same technology is still used today. But it wasn’t only through the smelting of metals that charcoal had an impact on history.

Sometime in the 9th century, a Chinese alchemist discovered that blending charcoal with saltpeter (potassium nitrate) and sulfur resulted in a mixture that would combust readily. “Gunpowder” would eventually be used to create explosives that gave access to coal and minerals, making huge engineering achievements possible. Of course, gunpowder also made possible the easier destruction of life, casting a dark shadow on charcoal.

North and South American people, Africans, and Europeans also made and used charcoal. People generally made charcoal by piling wood up and covering it with dampened dirt and then lighting the wood on fire to burn very slowly without much oxygen. The best charcoal comes from burning hardwood like oak or beech. The result is mainly carbon, like coal.

 Charcoal briquettes are made from the sawdust of scrap wood and were invented in 1919 (including resinous softwoods and composite woods). It was combined with chemical binders and filler (including coal dust) and manually compressed into their characteristic pillow shapes. Slower to light, often requiring lighter fluid.

The important raw material of charcoal briquette is coconut shell. And coconut shell charcoal has wide applications in many fields because of its features and advantages. Due to their high carbon content and hardness, coconut shells are an excellent raw material source to produce activated carbon. Activated carbon manufactured from coconut shells is considered superior to those obtained from other sources. They typically have a tighter, more microporous pore structure and tend to be harder, more resistant to abrasion, and lower in ash than similar grades of coal-based carbons.
