The invention relates to a carya cathayensis hull biomass particle. The carya cathayensis hull biomass particle comprises the following raw materials in parts by weight: 70 to 85 parts of carya cathayensis hull, 24 to 35 parts of coconut shell, 20 to 28 parts of oil palm residue, 21 to 30 parts of peanut cake, 18 to 28 parts of tea oil cake, 15 to 21 parts of carya cathayensis dead leaf meal, 6 to10 parts of turf, 12 to 19 parts of pine tree dead leaves, 11 to 16 parts of coal meal, 5 to 8 parts of sodium nitrate, 10 to 15 parts of dry cow dung, 8 to 14 parts of dry sheep manure, 6 to 10 parts of silkworm excrement, 16 to 25 parts of glycerinum, 8 to 13 parts of an ethanol water solution, 20 to 32 parts of carya cathayensis residue and 2 to 4 parts of a combustion adjuvant. According to the carya cathayensis hull biomass particle disclosed by the invention, a biomass energy fuel is prepared from the carya cathayensis hull, so that the pollution of carya cathayensis hull to the environment is governed, and the ecological environment is protected from the source; and moreover, the waste materials are changed into valuable things, the industry chain of carya cathayensis is extended,the profit of local farmers is increased, and the materials of the fuel are wide and variable in sources.
