Abstract

The invention relates to the field of biological energy, in particular to a method for producing light oil from biomass through liquefaction. Biomass slurry is prepared through specific steps as follows: plant oil residues are subjected to drying, primary smashing, compressing and secondary smashing in sequence and then mixed with a hydrogenation catalyst and a vulcanizing agent, a mixture is obtained and added to solvent oil to be ground into slurry, and the biomass slurry with plant oil residue concentration being 50wt%-65wt% is prepared. The plant oil residues are subjected to first compression and later secondary smashing initiatively with the treatment technology, the loose plant oil residues are subjected to re-arrangement, mechanical deformation and other stages successively by means of compression of biomass, so that density and specific gravity of the plant oil residues are increased, dispersion of the plant oil residues into the oil product is facilitated, content of the plant oil residues in the oil product can be increased, concentration of reaction materials is increased, delivery amount of the biomass in unit time by a pump is increased, and stable operation and delivery of the pump are guaranteed.

Description

technical field [0001] The invention belongs to the technical field of biomass liquefaction, and in particular relates to a method for producing light oil through biomass liquefaction. Background technique [0002] All organic matter that can grow is collectively referred to as biomass. In a broad sense, biomass refers to all plants, microorganisms, and animals that feed on plants and microorganisms and their waste; in a narrow sense, biomass is mainly Refers to vegetable oil residues such as soybean oil residues other than grains and fruits in the process of agricultural and forestry production, lignocellulose such as trees (referred to as lignin), leftovers from agricultural product processing, agricultural and forestry waste, and poultry manure and animal manure in the process of animal husbandry production. waste, etc. Common representative biomass includes crops, crop waste, wood, wood waste, and animal manure. There is interdependence and interaction between various ...
