▎ 摘　　要

NOVELTY - Biomass energy fuel comprises 42-68 pts. wt. agricultural waste, 15-22 pts. wt. graphene, 10-25 pts. wt. crab shell, 5-15 pts. wt. calcium magnesium carbonate, 15-25 pts. wt. behenic acid, 10-20 pts. wt. plant oil slag, 10-18 pts. wt. feces, 6-15 pts. wt. xylo-oligosaccharide and 5-10 pts. wt. seaweed. USE - Biomass energy fuel. ADVANTAGE - The biomass energy fuel is cost effective and fit for large-scale popularization, and has good performance, burning time of high combustion heat and long and high degradation rate. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method for preparing biomass energy fuel, which involves: (A) weighing agricultural waste, graphene, crab, magnesium calcium carbonate, behenic acid, plant residue, excrement, xylo-oligosaccharide and seaweed powder; (B) crushing excrement after drying, calcining at 200-400 degrees C and cooling to obtain viable septic; (C) crushing agricultural waste, calcining at 120-200 degrees C and cooling to obtain agricultural waste ash; (D) adding graphene, seaweed meal, crab and magnesium calcium carbonate, putting at 78-90 degrees C and mixing for 1-2 hours, adding behenic and xylo-oligosaccharide, putting into 75-85 degrees C and mixing for 1-2 hours; and (E) placing product at 80-90 degrees c and activating waste, agricultural waste ash and plant residue, mixing uniformly to obtain biomass energy fuel.
