Abstract

The invention relates to the field of biological energy, particularly to a process for producing fuel oil and chemical industry raw materials by using biomass. The slurry preparation steps comprises:sequentially carrying out drying, primary crushing, compressing and secondary crushing on vegetable oil residue, mixing the obtained material, a first catalyst and a vulcanizing agent to obtain a mixture, adding the mixture to an oil product, and carrying out grinding and slurry preparing to prepare the biomass slurry with the vegetable oil residue concentration of 50-65 wt%. According to the present invention, the vegetable oil residue is sequentially subjected to compressing and secondary crushing, wherein the loose vegetable oil residue is sequentially subjected to re-disposition, mechanical degeneration and other stages by compressing the biomass, such that the density and the specific gravity of the vegetable oil residue are increased so as to easily disperse in the oil product and improve the content in the oil product, increase the concentration of the reaction material, increase the biomass conveying amount of the pump per unit time, and ensure the smooth operation and transportation of the pump.

Description

technical field [0001] The invention relates to the field of biological energy, in particular to a process for producing fuel oil and chemical raw materials from biomass. Background technique [0002] Biomass in a broad sense refers to all organic substances formed directly or indirectly by photosynthesis of green plants, including plants, animals, microorganisms and their excretion and metabolites; biomass in a narrow sense includes vegetable oil residues such as palm oil residues and rice straw, etc. Plant straw. Biomass is renewable, low-pollution and widely distributed. Therefore, from the perspective of energy security and environmental protection, the development and utilization of biomass has become the strategic focus of the current development of renewable energy. [0003] Biomass liquefaction technology is an important part of the utilization of biomass resources. The liquefaction mechanism of biomass is as follows: biomass is first cracked into oligomers, and the...
