One-pot liquefaction process of biomass

Abstract

The invention relates to the field of biological energy sources, in particular to a one-pot liquefaction process of biomass. The process comprises the following steps: firstly, preparing slurry containing a catalyst, a vulcanizing agent and biomass, and then introducing hydrogen into the slurry for carrying out a reaction. The slurry is prepared by the steps of sequentially carrying out drying, primary crushing, compressing and secondary crushing on plant oil residue, and then mixing the product with the catalyst and the vulcanizing agent to obtain a mixture; adding the obtained mixture into an oil product, and grinding to prepare slurry, wherein the prepared slurry is biomass slurry with a plant oil residue concentration of 50-65wt%. According to the one-pot liquefaction process of the biomass, a treatment process of first compressing and then secondary crushing is carried out on the plant oil residue for the first time, so that the volume of the plant oil residue is greatly reduced,the plant oil residue is more easily dispersed in the oil product, the content of the plant oil residue in the oil product is increased, and the concentration of a reaction material is increased; theone-pot liquefaction process increases the biomass conveying capacity of a pump within unit time, and guarantees the smooth operation and transportation of the pump.

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. In a broad sense, biomass refers to all directly or indirectly available green plants formed by photosynthesis. Biomass in the narrow sense includes plant oil residues such as palm oil residues and plant straws such as ric...
