Description

A kind of composite biomass liquid fuel
Technical field
The present invention relates to new energy fuel field, particularly a kind of environment friendly and pollution-free composite biomass liquid fuel.
Background technology
At present, along with the appearance of energy dilemma in world wide and the day by day serious environmental problem owing to using mineral fuel to bring in a large number, the exploitation to biomass energy are more and more paid attention in countries in the world.
Biomass liquid fuel is a kind of Land use systems of biomass energy, and its raw materials for production are forestry " three surplus things " (wood machining residues, forest harvesting residuum, producing material residuum), various wooden tankage, wood wastes, agricultural crop straw and shrub etc.Production process be quality is loosened, can the little biomass material of force density, through the operation such as super-dry, pulverizing, then after high-temperature pressure thermo-cracking, obtain biomass liquid fuel.Biomass liquid fuel energy density is large, and combustion heat value is large, and conveniently, not having sulfur dioxide emissions, is a kind of environment friendly and pollution-free ecological fuel for transport and storage.
No. 201010517711.8th, Chinese patent application discloses a kind of biomass liquid fuel, it obtains a kind of biomass liquid fuel after carrying out thermo-cracking to biomass material, but this fuel combustion value is relatively low, the boiler oil such as kerosene, heavy oil cannot be replaced completely, and due to composition single, transport and use time easily there is fuel knock phenomenon.
Summary of the invention
For the defect existed in prior art, invention has been improvement, a kind of composite biomass liquid fuel provided, combustion heat value is high, pollution-free, good stability, storage transportation safety is convenient, can be used as clean energy and substitutes the mineral fuel such as existing kerosene, heavy oil.
Technical scheme of the present invention is summarized as follows:
A kind of composite biomass liquid fuel, it is obtained by material normal temperature mix and blend under 0.5Mpa ~ 1.0Mpa pressure of following mass percentage for 6 hours:
Wherein, described biomass pyrolysis liquid is obtained by following methods: after biomass material drying, pulverizing, in rapid pyrolysis reactor, carry out heat scission reaction, collect the liquid of condensation, obtain biomass pyrolysis liquid;
The wood chip that described biomass material is selected from wooden tankage, wooden waste products, wood working produce, wheat stalk, maize straw, broomcorn straw, cotton stem, rice straw, beans stalk, Pericarppium arachidis hypogaeae or its combination;
Described stopper is selected from cuprous chloride, iron trichloride, Resorcinol, Meta-dinitrobenzene, 2,5 di tert butyl hydroquinone or its combination;
Described emulsifying agent is selected from polyoxyethylene nonylphenol ether, Ben-zylphenol Polyoxyethyl Ether, octadecane alcohol radical Soxylat A 25-7, polyoxylethylene abietate, Glycerol dimer polypropylene glycol ether, di-isopropyl sodium naphthalene sulfonate, xenol Soxylat A 25-7 formaldehyde condensation products, Dodecyl trimethyl ammonium chloride or its combination;
Described octane promoter is made up of following material: the methyl cyclopentadiene three carboxyl manganese of 5wt%, the mono methyl aniline 99.5004323A8urity of 25wt%, the isobutyl acetate of 30wt%, the methyl tertiary butyl ether of 40wt%.
Preferably, described composite biomass liquid fuel, the described alkane mixed solution containing 6 ~ 8 carbon atoms is the normal alkane mixed solution containing 6 ~ 8 carbon atoms.
Preferably, described composite biomass liquid fuel, biomass material being dried to water ratio is 10wt% ~ 16wt%.
The invention has the beneficial effects as follows: the calorific value being added this liquid fuel by interpolation alkane and alcohol, the introducing of octane promoter effectively prevent the generation of fuel knock phenomenon, composite biomass liquid fuel calorific value mentioned by the present invention is high, pollution-free, good stability, storage transportation safety is convenient, can be used as clean energy and substitutes the mineral fuel such as existing kerosene, heavy oil, gasoline, diesel oil, for multiple fields such as generating, urban heat supplying, motor-driven vehicle goings.
Embodiment
Below in conjunction with embodiment, the present invention is described in further detail, can implement according to this with reference to specification sheets word to make those skilled in the art.
A kind of composite biomass liquid fuel, it is obtained by material normal temperature mix and blend under 0.5Mpa ~ 1.0Mpa pressure of following mass percentage for 6 hours:
Wherein, the alkane mixed solution containing 6 ~ 8 carbon atoms is preferably the normal alkane mixed solution containing 6 ~ 8 carbon atoms.Alkane mixed solution containing 6 ~ 8 carbon atoms can select oneself alkane, heptane, octane or its combination, the combustionproperty of three is close, so can with arbitrarily than mixing, whether also do not limit alkane used in this case must be normal alkane, the structure of this type of alkane is limited on combustionproperty impact, therefore only need containing the alkane containing 6 ~ 8 carbon atoms in this case.Same, the monohydroxy-alcohol mixed solution containing 2 ~ 4 carbon atoms is not also particularly limited the structure of alcohol, and it can be selected from ethanol, propyl alcohol, butanols or its combination, and can any combination.
The object inserting alkane mixed solution and alcohol mixed solution in biomass pyrolysis liquid is the energy density in order to improve this liquid fuel, increases its combustion heat value, to expanding the Application Areas of this fuel further.
Biomass pyrolysis liquid is obtained by following methods: be after 10wt% ~ 16wt%, pulverizing by biomass material drying to water ratio, carry out heat scission reaction, collect the liquid of condensation, obtain biomass pyrolysis liquid in rapid pyrolysis reactor;
The wood chip that biomass material is selected from wooden tankage, wooden waste products, wood working produce, wheat stalk, maize straw, broomcorn straw, cotton stem, rice straw, beans stalk, Pericarppium arachidis hypogaeae or its combination;
Stopper is selected from cuprous chloride, iron trichloride, Resorcinol, Meta-dinitrobenzene, 2,5 di tert butyl hydroquinone or its combination;
Emulsifying agent is selected from polyoxyethylene nonylphenol ether, Ben-zylphenol Polyoxyethyl Ether, octadecane alcohol radical Soxylat A 25-7, polyoxylethylene abietate, Glycerol dimer polypropylene glycol ether, di-isopropyl sodium naphthalene sulfonate, xenol Soxylat A 25-7 formaldehyde condensation products, Dodecyl trimethyl ammonium chloride or its combination;
Octane promoter is made up of following material: the methyl cyclopentadiene three carboxyl manganese of 5wt%, the mono methyl aniline 99.5004323A8urity of 25wt%, the isobutyl acetate of 30wt%, the methyl tertiary butyl ether of 40wt%.
Owing to containing a large amount of unsaturated materials in biomass pyrolysis oil, can be polymerized gradually in heating or storage process and lose flowability, impact is normal to be used, this case with the addition of stopper and emulsifying agent in technical recipe for this reason, they effectively can improve stability in storage and the mobility of biomass pyrolysis oil, the stable storing time is long, and pour point is low.
After biomass pyrolysis liquid mixes with alkane, alcohol, after long-term transport or storage, can produce more active superoxide, easily there is phenomenon of detonation in fuel, effectively can avoid problems by adding a small amount of octane promoter.
The calorific value of obtained composite biomass liquid fuel is at 8000 ~ 9600Kcal/kg.
