preparation example Construction

[0035] The present invention also provides a method for preparing a composition for biomass oil, the method comprising mixing biomass with liquid oil to obtain a mixed liquid; wherein, based on the weight of biomass, the biomass has a water content of 3-18wt% , preferably, the biomass has a moisture content of 5-10 wt%. Preferably, based on 100 parts by weight of the total weight of the composition for biomass oil, the biomass accounts for 10-40 parts by weight, preferably 30-40 parts by weight, and the biomass is mixed with the liquid oil.

[0036] Before the biomass is mixed with liquid oil, the biomass is subjected to a pretreatment process, which is to dry the biomass so that the water content in the biomass meets the above requirements, and then crush the dried biomass to obtain the volume particle size Distribute the solid biomass particles within the range of 1 μm-5000 μm, preferably 20 μm-200 μm, and finally carry out ash removal treatment on the solid biomass particle...

Embodiment 1

[0042] Drying the wheat straw so that the water content in the wheat straw is 18wt%, and then pulverizing the dried wheat straw to obtain wheat straw particles with a volume particle size distribution range of 20 μm-200 μm, and finally deashing the wheat straw particles deal with.

[0043] According to 100 parts by weight of the total weight of the composition for biomass oil, 5 parts by weight of a hydrocracking catalyst (commercially available amorphous iron oxyhydroxide) is mixed with the wheat straw particles after deashing, and at the same time, 0.4 parts by weight of sulfur is added as a vulcanizing agent. Then, the obtained mixture is mixed with commercially available peanut oil based on 100 parts by weight of the total weight of the composition for biomass oil, and wheat straw particles account for 35 parts by weight, and the mixture is mixed with peanut oil to obtain a mixed slurry.

Embodiment 2-5

[0045] Embodiment 2-5 has adopted the processing step identical with embodiment 1, and difference is as shown in table 1:

[0046] Table 1

[0047]

[0048] It should be noted that the biomass oil used in Example 5 is the biomass oil 4# obtained in the subsequent hydrohydrolysis of Example 4.

Abstract

The invention provides a biomass oil composition and a preparation method and application thereof. The composition includes biomass and liquid oil; the biomass has a water content of 3 to 18 wt% basedon the weight of the biomass. The biomass and the liquid oil are mixed to obtain a mixed liquid, namely the biomass oil composition. The application is the application of the biomass oil compositionin the preparation of biomass oil, water in the biomass can be used for high pressure and high temperature hydrolysis, and under the joint action of hydrogen and a catalyst, the coke condensation is avoided, the coke yield is reduced, and the yield of the biomass oil is improved.

Description

technical field [0001] The invention belongs to the technical field of bioenergy, and relates to a composition for biomass oil, its preparation method and its application in the preparation of biomass oil, in particular to a composition containing biomass with a certain water content, and its preparation by hydrolysis and hydrogenation Application of bio-oil. Background technique [0002] At present, petrochemical non-renewable energy sources such as coal, crude oil, natural gas, and oil shale are becoming increasingly exhausted with the development of society, and the CO produced after their combustion 2 , SO 2 , NO x Such pollutants have caused increasingly serious environmental pollution, which forces people to seriously consider ways to obtain energy and methods to improve the environment. [0003] Biomass refers to all organic substances formed directly or indirectly by photosynthesis of green plants, including plants, animals, microorganisms and their excretion and ...
