A kind of biomass fuel slurry and preparation method thereof

Abstract

The present invention provides a biomass fuel slurry and a preparation method thereof, which is characterized by comprising the following steps: 1) biomass heating and drying, pulverizing into biomass powder; 2) adding acid solution to biomass powder for heating treatment, and then adding alkali 3) Add water to the biomass dispersion and stir evenly, and heat it by hydrothermal method in an oven at 80°C for 2 hours; 4) Then add formaldehyde, sodium sulfite, linoleic acid, alkyl Phosphorus carboxylate, after stirring evenly, keep the temperature and continue the reaction to obtain the biomass fuel slurry. The biomass fuel slurry prepared by the preparation method has good fluidity and stability.

Description

technical field [0001] The invention relates to a fuel slurry prepared by using biomass as a main raw material and a preparation method thereof. Background technique [0002] Coal accounts for about 72% of my country's total energy consumption as primary energy consumption. For a long time, my country's energy consumption structure will still be dominated by coal. With the improvement of environmental requirements, there is an urgent need for a clean fuel. [0003] my country is a large agricultural country with rich forest resources, which produce a large amount of agricultural and forestry waste such as fruit shells, straw, and sawdust. Using these renewable biological wastes as fuel is an effective green energy model. [0004] Biomass is a hydrophobic substance after drying and pulverization, and the particle size is very fine, with a large specific surface area, and it is difficult to be closely combined with water to form a slurry. And because of its density differenc...
