摘要:
A pelletized fuel composition is made from a mixture of coal fines, and cellulosic by-product from ethanol production. The coal fines range from about 50%-90% by weight and the cellulosic by-product ranges from about 10%-50% by weight of the composition. The cellulosic by-product is a syrup or a cake. The syrup binds the coal fines. The coal fine and syrup mixture is pelletized to produce a solid fuel product that is easily handled and transported.
摘要:
A pelletizing process and pelletized product is provided using non-food or limited-feed agricultural residue, such as corn stover and soybean stubble, and for various uses, including energy production, such as ethanol or electricity generation, fuel and feed. The agricultural plant material is harvested and baled. The bales are transported to the processing site for storage or immediate processing. The bale strings are first removed, and then the broken bales are shredded. The shredded plant material is then ground to a small size. The ground material is then pelletized without the use of binding additives, to produce densified pellets of the agricultural plant material. The pellets are cooled and then stored or transported to an end user. Chemical agents may be added to depolymerize lignin in the residue material. Nutritional supplements may be added to the material before pelletizing.
