NOVELTY - Composite biomass pellet fuel comprises 95.6-96% fuel matrix, 0.6-0.8% graphene and 3.2-3.8% coconut shell powder. The fuel matrix comprises 30-40 pts. wt. wheat straw, 20-30 pts. wt. sawdust, 20-30 pts. wt. corncob, 20-25 pts. wt. peanut shell, 20-25 pts. wt. straw, 15-20 pts. wt. husk, 15-20 pts. wt. oil tea shell and 15-20 pts. wt. cottonseed hull. USE - Composite biomass pellet fuel used as biofuel product (claimed). ADVANTAGE - The fuel has high combustion efficiency, moderate combustion speed, long combustion duration and ability to gently release combustion heat and continuous heating. DETAILED DESCRIPTION - Composite biomass pellet fuel comprises 95.6-96% fuel matrix, 0.6-0.8% graphene and 3.2-3.8% coconut shell powder. The fuel matrix comprises 30-40 pts. wt. wheat straw, 20-30 pts. wt. sawdust, 20-30 pts. wt. corncob, 20-25 pts. wt. peanut shell, 20-25 pts. wt. straw, 15-20 pts. wt. husk, 15-20 pts. wt. oil tea shell and 15-20 pts. wt. cottonseed hull. The preparation comprises drying wheat straw, sawdust, corn cob, peanut shells, straw, rice husk, tea oil shell and cotton seed shell, crushing, sieving to 40 mesh, mixing to obtain fuel matrix, adding graphene and coconut shell powder to fuel matrix, mixing, adding water, mixing, extruding and cooling to room temperature.
