Abstract

The invention belongs to the technical field of fuel preparing, and particularly relates to a lignin-containing biomass fuel and a preparing method thereof. The lignin-containing biomass fuel is prepared from straw-light-ash-containing biomass sludge, straw light ash, lignin and cellulose mud. According to the biomass fuel, organic waste obtained through biomass resource treatment is fully used, and enormous economic benefits and enormous environment-protection benefits are achieved. In addition, plant materials such as the straw light ash are added into non-dewatered sludge, and the heat value of dewatered sludge can be increased; as plant fibers such as the straw light ash are mixed into the sludge, the frictional force of pre-dewatered sludge in a screw squeezing dewatering machine is improved, the running frequency of the screw squeezing dewatering machine can be further increased, and the running efficiency and the mud-discharging dryness degree of the machine are effectively increased.

Description

technical field [0001] The invention belongs to the technical field of fuel preparation, and in particular relates to a biomass fuel containing lignin and a preparation method thereof. Background technique [0002] One of the important research directions for the comprehensive utilization of biomass resources is to obtain cellulose, hemicellulose and lignin from biomass resources through separation technology, and the three are collectively referred to as "three elements". Lignin is an aggregate with a variety of polar groups in the structure, resulting in strong intramolecular and intermolecular hydrogen bonds, so lignin is originally insoluble in water and any solvent. There are a variety of functional groups in the molecular structure of lignin, such as aromatic groups, phenolic hydroxyl groups, alcoholic hydroxyl groups, carbonyl groups, methoxyl groups, carboxyl groups, conjugated double bonds, etc., so they can undergo redox, hydrolysis, acidolysis, photolysis, and bio...
