What is pellet chemistry?

Pellets are small, cylindrical, or oval-shaped fuel made from organic materials such as wood, grass, and other biomass. The chemistry of pellets plays a significant role in how they perform as fuel. Generally, pellets must have low moisture content, consistently sized and shaped, and high-energy content.

The chemistry of pellets involves the use of bonding agents and additives to improve their properties. Some common bonding agents used in pellet production include lignin and starch. Lignin is a naturally occurring polymer in biomass that acts as a natural glue. Starch is a carbohydrate that can act as a glue to hold the pellets together.

Additives are also used in the pellet production process to improve the quality of pellets. Some common additives include anti-caking agents, lubricants, and desiccants. Anti-caking agents are used to prevent pellets from clumping and sticking together. Lubricants are used to reduce friction during the pellet production process and improve pellet flowability. Desiccants are used to reduce the moisture content of pellets, thereby improving their energy content.

In summary, the chemistry of pellets involves the use of bonding agents and additives to improve pellet quality and performance. Pellets with high-quality chemistry will have consistent size and shape, low moisture content, and high-energy content.
