Aforesaid method, optimized technical scheme is: when selecting algae, fresh water waterplant or their mixture for use, also add account for the heavy 0.1-8% of raw material metal-salt as catalyzer, this metal-salt is mainly yellow soda ash, salt of wormwood, magnesium chloride, calcium chloride, bariumchloride, magnesiumcarbonate, lime carbonate, barium carbonate or their mixing.More preferred selection is: the consumption of described metal salt catalyst is to account for the heavy 2-5% of raw material.
Aforesaid method, optimized technical scheme is: when selecting for use exsiccant algae and/or waterplant to be raw material, add entry or alcohol as heat-transfer medium, make algae and/or waterplant material content account for the 0.5-20% of material gross weight in the reactor.When adopting alcohol as heat-transfer medium, selected alcohol is mainly short carbon chain alcohol, for example methyl alcohol and ethanol.When algae and/or waterplant raw material are wet feed or have just collected from water and when not carrying out the exsiccant material, do not need additionally to add heat-transfer medium.
Aforesaid method, optimized technical scheme is: place closed reactor also to need before algae and/or waterplant are pulverized algae and/or waterplant.Disintegrating apparatus can be selected the conventional equipment of tissue mashing machine, plant pulverizer and so on for use.
The present invention is the method for feedstock production fuel with algae and/or waterplant, and described algae can be selected macro, is meant marine algae and algae or their mixing that all can provide bio-energy.Described marine algae comprises: all marine algas of phaeophyta, Chlorophyta and rhodophyta.Described fresh water algae comprises all algae that are born in the fresh water.
The present invention is the method for feedstock production fuel with algae and/or waterplant, and described waterplant comprises all plants of orthobiosis in water for a long time, comprises emergent, floatingleaved plant, submerged plant and free-floating plant.For example: lotus, calamus, Scirpus tabernaemontani, cattail, reed, water lily, Wang Lian, water chestnut, floating heart, field word apple, black algae, hornwort, eel grass, water caltrop, watermifoil, Herba Eichhorniae, float greatly, waterplant such as frogbit, Herba azollae imbricatae, Chinese scholartree Ye Ping.
The present invention is the method for feedstock production fuel with algae and/or waterplant, after reaction is finished, collects the gas that is produced, and this gas is combustible gas, mainly consists of methane, hydrogen, carbon monoxide, and content is about 30-80%.Collect remaining product liquid and distill, the cut between 45-450 ℃ is the liquid fuel that main component is alkane, naphthenic hydrocarbon and aromatic hydrocarbon, and output reaches 10-30%.
In addition, technical superiority of the present invention also is embodied in:
1, technology of the present invention is simple, but coproduction prepares liquids and gases fuel.
2, algae of the present invention and waterplant can not need extra drying, have saved the extra energy, have simplified technology, are particularly suitable for water content than higher biomass material.
3, algae and waterplant have advantages such as biomass is big, growth cycle weak point, fast growth, utilize present method process gas and liquid fuel no matter from point of view of environment protection still from the angle of power supply, all have very important significance.
