Abstract
The present invention discloses a preparation method of biological oil. It uses the biomass hydrolyzed residue as raw material, in the pressure ange of (gauge pressure) 0.01-0.1 MPa and temp. range of 400-600 deg.c the raw material is placed in reactor, and its residence time is 0.5-10 sec., and under the condition of that the non-condensable gas produced by cracking reaction is used as fluidizing gas and carrier gas a quickly-cracking mode is used to obtain the invented biological oil. The liquid yield rate can be up to 70%, and said biological oil is low in oxygen content, stable in oil quality, and is easily refined.
Description
Technical field
The present invention relates to a kind of preparation method of bio oil, relating to a kind of specifically is the method for feedstock production bio oil with the biomass by hydrolyzation residue.
Background technology
The energy and and environmental problem become the focus that the whole world is paid close attention to.Along with industrialized progress, the mankind have consumed a large amount of fossil class energy, cause petering out of these resources, have brought the serious environmental pollution on the other hand again, and a large amount of dischargings of carbonic acid gas have caused Greenhouse effect.People begin to seek substitute energy for this reason, and biomass cause people's interest just day by day as a kind of important renewable energy.
Biomass typically refer to based on terrestrial plant of xylogen, Mierocrystalline cellulose, hemicellulose and other organic matters (timber, yule logs, stalk etc.) and waterplant etc., are a kind of stable renewable energy source resources.It is compared with fossil energies such as oil with coal, not only sulphur, nitrogen content low (S, 0.1-1.5%; N, 0.5-3%), ash low (0.1-3%), and the source is abundant, only China's agricultural crop straw output is about 700,000,000 tons every year, and the stock number that can be used as the energy is hundred million tons of 2.8-3.5; The year rational exploitation amount of yule logs is about 1.58 hundred million tons, also has a large amount of waterplant in addition.Therefore biomass are called the green energy resource of instant utilization, account for 14% of world energy sources consumption at present.
It is raw material production fuel alcohol and bio oil that the development and utilization of biomass mainly concentrates on biomass.Hemicellulose and cellulose hydrolysis obtain monose when producing fuel alcohol, and xylogen stays as residue.With biomass is that the bio oil that raw material makes mainly exists oxygen level height (40%) and poor heat stability (being heated to 120 ℃ is that coking becomes the sponge coke body) defective, thereby cause it can not be directly as motor spirit, in addition, because the cause of raw material (biomass) makes prepared bio oil also polycondensation can take place, thereby cause its storage and transportation difficulty.
Summary of the invention
The technical issues that need to address of the present invention provide a kind of preparation method of bio oil and the treatment process of biomass by hydrolyzation residue, solve the defective that prior art exists with this.
Design of the present invention
Different biomass kinds, the content of each component can be different.As mainly containing components such as Mierocrystalline cellulose, hemicellulose and xylogen in the xylophytas such as wood chip.General hemicellulose accounts for 20-35%, cellulose comprises 40-55%, and xylogen accounts for 20-30%; And hemicellulose level is 19-25% in the herbaceous plant such as wheat straw, and Mierocrystalline cellulose is 38-43%, and xylogen is 16-21%, ash 12-14%.Mierocrystalline cellulose in the biomass and hemicellulose can obtain reductive monosaccharide, furfural, hydroxymethylfurfural and levulinic acid etc. through hydrolysis.Reductive monosaccharide can obtain alcohol through fermentation, and furfural etc. also are important chemical material.And in hydrolytic process, xylogen does not react substantially.The energy density of xylogen (27MJ/kg) is than Mierocrystalline cellulose (17MJ/kg) height.Behind the biomass by hydrolyzation, reduced more hemicellulose and the Mierocrystalline cellulose of hydroxyl, if be cracking stock with the biomass by hydrolyzation residue, oxygen level in the cracked oil that obtains is low, improve the stability of bio oil, reduced the aqueous portion in the bio oil, thereby improved the quality of bio oil.
Technical scheme
Bio oil preparation method's of the present invention key step is:
Raw material is placed the cracking reactor cracking, and cracking temperature is 400-600 ℃, and cracking pressure is the residence time of 0.01-0.1MPa raw material in cracking reactor to be preferably 0.5-10 second, and split product obtains bio oil after condensation.
Wherein said raw material is biomass, comprises agricultural wastes, as: stalk, shell, fruit stone, the waste of agricultural byproducts such as corn cob; Forestry waste, as: fuel wood, fallen leaves, bark, tree root and forestry processing waste; Waterplant, as: algae, duckweed, Herba Eichhorniae, jacinthe etc.; Energy crop is as: oil crops be rich in the plant etc. of hydrocarbon polymer and other growth remaining residue after acid hydrolysis or enzymic hydrolysis of biomass.Its method for hydrolysis is referring to Yan Yongjie, Ren Zhengwei.The research of Mierocrystalline cellulose continuous catalysis hydrolysis.Solar energy journal.1999，20(1)：55-58。
