Abstract

The invention provides a one-pot liquefaction process of biomass. The slurry preparation steps comprise: sequentially carrying out drying, primary crushing, compressing and secondary crushing on vegetable oil residue, mixing the obtained vegetable oil residue, a catalyst and a vulcanizing agent to obtain a mixture, and adding the mixture to water to obtain the slurry with the vegetable oil residueconcentration of 40-50 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 so as to substantially reduce the volume of the vegetable oil residue, such that the density and the specific gravity can be increased, the vegetable oil residue can be easily dispersed in the water, the vegetable oil residue content in the water can be increased, the biomass conveying amount of the pump per unit time can be increased so as to improve the efficiency of the whole biomass liquefaction process and reduce the industrial cost and the energy consumption, and the smooth operation and transportation of the pump can be achieved.

Description

technical field [0001] The invention relates to the technical field of bioenergy conversion, in particular to a one-pot liquefaction process of biomass. Background technique [0002] Coal, crude oil, natural gas, oil shale and other fossil non-renewable energy sources are becoming increasingly exhausted with the rapid development of social economy, and the CO produced after their combustion 2 , SO 2 , NO x The increasingly serious environmental pollution caused by such pollutants has forced human beings to seriously consider ways to obtain energy and methods to improve the environment. Biomass is a kind of renewable energy, which has huge potential and advantages in meeting energy demand, reducing environmental pollution, and improving energy structure. Biomass refers to all organic substances formed by photosynthesis of green plants that can be directly or indirectly used , including plants, animals, microorganisms and their excretion and metabolites, which are renewable...
