Description
Technical field:
The present invention relates to a kind of new methods of biomass by hydro-thermal liquefaction bio oil processed, are reacted with aluminium-water production hydrogen for hydrogen supply
Source, collaboration biological material catalytic liquefaction prepare bio oil, quality of bio-oil can be improved；Belong to environmental protection and new energy technology
Field.
Background technique:
With the fossil fuel reserves such as petroleum increasingly reduce and problem of environmental pollution it is increasingly serious, research and develop stone
Oily alternative fuel new technology has alleviation China's oil energy crisis, the improvement serious situation of problem of environmental pollution strategic
Meaning.Biomass is can be uniquely converted into the renewable energy of liquid fuel, there is that yield is huge, can store and be able to achieve carbon and follow
The advantages such as ring.
Biomass economy mainly includes physical transformations technology, biochemical conversion technology, thermochemical study technology.Physical transformations
Technology mainly passes through addition additive and external force compression is fabricated directly into shaped fuel.Biochemical transformation technology is mainly benefit
With enzyme and microbial degradation biomass, such as ferment.Thermochemical study technology is the biomass degradation by way of heating, is such as pyrolyzed
And liquefaction.Pyrolysis is that organic matter is degraded into a kind of thermal transition technology of small-molecule substance under an inert atmosphere.Thermal decomposition product master
There are bio oil, charcoal, tar and cracking gas etc..It is the important component of current biomass thermal transformation technology.Liquefaction is close
A kind of thermal transition mode that a little years rise.Biomass liquefying technology refers in elevated pressures, certain temperature and solvent, catalyst etc.
The technology that liquefaction reaction produces liquid product is carried out to biomass under the conditions of existing, usually using water as reaction medium, therefore
Also referred to as hydrothermal liquefaction.
Biomass bio oil as made from liquefaction has many advantages, such as safe and clean, there is a good researching value, thus by
Pay attention to extensive.But the shortcomings that bio oil elevated oxygen level, low heat value make it difficult to directly to burn on existing or with
Fossil fuel gasoline, diesel oil etc. are mixed and burned.Therefore purification need to be modified to bio oil, and catalytic hydrogenation be current effect most
Good is also to apply most method of modifying, can be divided into direct hydrogenation according to hydrogen source difference in catalytic hydrogenation and original position supplies
Hydrogen.Direct hydrogen supply is mostly used plant hydrogen, and reaction needs to carry out under certain hydrogen pressure (4Mpa), but the method the producing of hydrogen,
There are problems that high cost and high risk during transhipment, storage.Hydrogen supply in situ is the hydrolysis and heat chemistry using hydrogen supply agent
Reaction generates hydrogen, and a kind of method of hydrogen is added directly in liquefaction process.Hydrogen supply in situ is due to can avoid many of direct hydrogen supply
Problem has become method of greatest concern in bio oil study on the modification.Hydrogen supply in situ uses the inorganic hydrogen supply based on salt more
Organic hydrogen supply agent such as agent and tetrahydronaphthalene, small molecule liquid alcohol, but the problems such as generally existing hydrogen output is low, and some hydrogen supplies
Agent is to environment nocuousness.Aluminium is the metal that reserves are most on the earth, and aluminium hydrolysis can not only generate hydrogen (theoretical hydrogen amount
1244mL/g (Al)), moreover it is possible to it gives off energy, and reaction product environmental sound.The reaction of such as aluminium-water, zinc-water once by
Overcritical lower coal, pitch and model compound for water add hydrogen, and when zinc, aluminium are oxidized, the hydrogen of generation is for organic matter
Hydrogenation reaction.But aluminium-water reaction production hydrogen hydrogen supply mode in situ is used for the experimental study in biomass by hydro-thermal liquefaction process simultaneously
It is rare.
Summary of the invention
For the high cost of direct hydrogen supply, high risk and tradition hydrogen supply agent in situ it is insufficient and to environment for hydrogen efficiency
Harmful problem proposes a kind of novel biomass method in situ for liquefaction of hydrogen bio oil.The present invention is with aluminium-water production hydrogen
