A review of the mechanism of bonding in densified biomass pellets

The production of durable biomass pellets have always been challenged by several factors including the lack understanding mechanism involved in how particles combine to form under standard conditions pellet press. This is because contributing span molecular, microscopic, and even nanoscopic levels as undergoes pelleting. characteristics bonds formed between combining their relevance quality remains vague, no matter defined. However, though few researchers attempted explain bonding densified using different theories, none hypotheses supports particle from a structural chemistry perspective. There are still clear explanations which consider role molecular structure interactions substances milled undergo In view these arguments therefore, this review presents an in-depth analysis perspective use additives helps identify research areas needed facilitate better pellets. status current pelleting, types materials suitable characteristics, well technical specifications also discussed.
