Embodiment 1

[0026] like figure 1 As shown, the present invention provides a method for utilizing biomass to produce liquid fuel, and the method for utilizing biomass to produce liquid fuel includes the following steps:

[0027] Step 1, pretreatment of biomass raw materials;

[0028] Step 2, microbial fermentation;

[0029] Step 3, separation and purification;

[0030] Step four, purification.

[0031] In this embodiment, the biomass raw materials are firstly pretreated to ensure that the subsequent processing process is not affected, and then the biomass raw materials are decomposed and transformed by microorganisms to convert them into usable liquid fuels, and then separated and purified. The by-products and impurities in the production process of liquid fuel are separated, and finally, the liquid fuel is separated from components with different carbon content through purification, so as to improve the utilization efficiency of liquid fuel.

Embodiment 2

[0033] like figure 1 As shown, on the basis of Example 1, the present invention provides a technical solution: preferably, the step 1 further includes, the biomass raw materials are sugar cane, corn and other sugar- or starch-containing food biomass or fast-growing It is composed of lignocellulosic biomass such as forest wood and discarded crop straw. The above biomass raw materials are concentrated and washed with high pressure to remove soil and ash on the biomass raw materials, and then the bulk solid impurities in the biomass raw materials are removed by flotation. , put the cleaned and flotated biomass raw materials into the crusher for crushing and mixing, crush them into suitable particles according to actual needs, and then dry the crushed biomass raw materials through a drying device to remove moisture. .

[0034] In this embodiment, the biomass raw materials are first cleaned and flotated to facilitate the removal of soil, ash and bulk solid impurities that cannot b...

Embodiment 3

[0036] like figure 1 As shown, on the basis of Example 1, the present invention provides a technical solution: preferably, the step 2 further includes: putting the pretreated biomass raw materials into the reactor, and putting the microorganisms into the reactor according to the proportion At the same time, keep the pressure in the reaction kettle at normal pressure and the temperature at 30 to 45 degrees Celsius. After standing for 6 hours, the reaction kettle is stirred by the stirring device, so that the biomass raw materials and the microbial starter are fully mixed and repeated. Two to three times of the above process, a large amount of gas will be generated during the fermentation of biomass raw materials. The gas contains combustible organic gas components and non-combustible gas components. The gas is continuously exported and collected through the pipeline to maintain the internal pressure balance of the reactor.

[0037] In this embodiment, during the fermentation pr...

Abstract

The invention discloses a method for producing liquid fuel by using biomass, and relates to the technical field of clean energy production, the method for producing liquid fuel by using biomass comprises the following steps: step 1, biomass raw material pretreatment, step 2, microbial fermentation, step 3, separation and purification, and step 4, purification. Biomass raw material residues, a microbial fermentation agent, liquid fuel, water, other incombustible micromolecular organic matter liquid and the like are fully fermented in a reaction kettle, and solid impurities and the liquid are separated through simple physical filtering operation; liquid fuel, water and non-combustible organic liquid are still contained in liquid obtained after solid-liquid separation, and then the liquid fuel, the water and the non-combustible organic liquid are separated through comprehensive utilization of physical and chemical separation and purification methods, so that the purity of the liquid fuel is improved, and the problem that the combustion process is insufficient due to the fact that the liquid fuel contains many impurities is solved.

Description

technical field [0001] The invention relates to a method for producing liquid fuel, and relates to the technical field of clean energy production, in particular to a method for producing liquid fuel by utilizing biomass. Background technique [0002] Traditional fuels are particularly prone to incomplete combustion during combustion, and the exhaust gas contains high levels of particulate matter, nitrogen oxides and hydrocarbons, causing great pollution and harm to the environment. Therefore, in order to cope with the shortage of oil resources and reduce environmental pollution, the development of low-carbon and environmentally friendly renewable energy has become a top priority. Biomass liquid fuel is a renewable energy that has attracted much attention in recent years. It is a clean and sustainable energy type. Therefore, there is still a lot of room for improvement in the use of biomass to produce liquid fuel. [0003] The following problems exist for the prior art: [...
