Abstract

The invention belongs to the technical field of new energy, and in particular relates to a preparation method of biomass liquefied fuel oil. According to the preparation method, the raw materials arefirstly processed: the raw materials are firstly mixed with an additive, and steam blasting is performed, the looseness of the raw materials is improved by treating with the steam explosion, and the porosity of the raw materials is improved by the effect of the additive; and then the raw materials are soaked with acetic acid, so that micropores and cracks can be formed inside the raw materials bysoaking in acetic acid; next the raw materials are mixed with iron sulfate and an auxiliary agent, so that the metal ions in the system can be sedimented by the effect of the mixed liquor to fill thepores in the raw materials, thereby forming a state of the iron-manganese-nickel three elements wrapping raw materials, and improving the catalytic efficiency of the raw material; meanwhile, the addedsucrose can effectively increase the carbon content of the raw materials and promote the liquefaction efficiency; and finally, in the liquefaction process, preheating can be performed to firstly improve the activity of the raw materials, and the liquefied fuel oil is obtained after the liquefaction at high temperature and high pressure.

Description

technical field [0001] The invention belongs to the technical field of new energy, and in particular relates to a preparation method of biomass liquefied fuel. Background technique [0002] With the rapid development of science and technology, the development of biomass energy will rely on innovative technologies to achieve greater development. The new technology of biomass energy, especially the research on rapid liquefaction of atmospheric pressure to produce liquefied oil, once a breakthrough is made, will greatly promote the development and application of biomass energy, especially in remote rural areas. Liquefied into "biological crude oil" that is convenient for transportation and rich in industrial processing value, the long geochemical process is concentrated in tens of minutes. [0003] The advantage of the atmospheric pressure liquefaction method of biomass is that it can produce a thermochemical reaction of biomass resources with a solvent medium at a lower tempe...
