Description
Technical field
The invention belongs to biomass energy trans-utilization technical fields, are specifically related to a kind of microwave radiation assist medium resistance
The method for keeping off discharge catalytic improving quality of bio oil.
Background technique
Biomass energy is can be uniquely directly changed into the renewable energy of carbonaceous liquid fuel, develops and uses it in fossil
Today that fuel is increasingly depleted and environment deteriorates increasingly becomes more and more important.The bio-crude oil being directly pyrolyzed by biomass
With properties such as high-moisture percentage, rich oxygen content, low heat value, highly acids, it is especially interior in existing heat power equipment seriously to hinder it
Use in combustion engine.Therefore, be added catalyst in the conversion process, carry out the catalytic pyrolysis of biomass or pyrolysis gas of biomass at
For improve bio-oil fuel grade effective means, wherein to pyrolysis gas of biomass carry out catalytic pyrolysis be advantageously implemented catalyst
Recovery and reusing and recycling, while be easily achieved pyrolysis and be catalyzed two parts temperature difference regulation.It is catalyzed and mentions online in bio oil
The catalyst being widely used in matter is HZSM-5 molecular sieve, and upgrading function and effect are the most obvious, obtain the extensive pass of researchers
Infuse (Tan S, Zhang ZJ, Sun JP, et al.Recent progress of catalytic pyrolysis of
biomass by HZSM-5[J].Chinese Journal of Catalysis,2013,34(4):641-650).But it is conventional
HZSM-5 is designed for petroleum industry, during bio oil online catalysis upgrading, the easy coking and deactivation (Wang of HZSM-5
J,Zhong ZP,Song ZW,et al.Modification and regeneration of HZSM-5 catalyst in
microwave assisted catalytic fast pyrolysis of mushroom waste[J].Energy
Conversion and Management, 2016,123:29-34), and polycyclic aromatic content is higher in hydrocarbon product
(Sun LZ,Zhang XD,Chen L,et al.Comparison of catalytic fast pyrolysis of
biomass to aromatic hydrocarbons over ZSM-5 and Fe/ZSM-5 catalysts[J].Journal
of Analytical and Applied Pyrolysis,2016,121:342-346).Valence can occur in catalytic process for Ti
State variation, meanwhile, the higher valence state of Ti ion and lesser radius make it have stronger polarizability, and catalysis can be remarkably reinforced
The cracking ability of agent.Catalyst can be improved to the selectivity of light hydrocarbons in Ti modification, delays the coking and deactivation of catalyst, is respectively changing
Property molecular sieve in show preferably (Cai YX, Fan YS, Li XH, et al.Preparation of refined bio-oil
by catalytic transformation of vapors derived from vacuum pyrolysis of rape
straw over modified HZSM-5[J].Energy,2016,102:95-105).Using dielectric barrier discharge mode
Low-temperature plasma synergistic catalysis is that the radical reaction for being caused electrion is reacted with the catalysis that catalyst is induced and had
A kind of new catalytic processing technique that machine combines.High voltage electric field provides big energy, anti-for decomposing, exciting and ionize
Object atom and molecule are answered, makes to change reactant rich in electronics, ion, free radical and excited state molecule in reactant and be catalyzed
The chemisorption behavior on agent surface improves selectivity (Fan YS, the Zhao WD, Shao of catalyst activity and chemical reaction
SS,et al.Promotion of the vapors from biomass vacuum pyrolysis for biofuels
under Non-thermal Plasma Synergistic Catalysis(NPSC)system[J].Energy,2018,
142:462-472)。
Although being modified to catalyst, and novel catalysis process is introduced, due to bio-crude oil or biology
Matter pyrolysis gas belongs to seriously scarce hydrogen feedstock (effective hydrogen-carbon ratio (H/C) eff is only 0.3-0.9), quite a few hydrogen in biomass
Element is present in pyrolysis gas (moisture content 25-50%) in the form of water, difficult to realize stablize to pyrolysis gas of biomass, hold
Continuous catalysis；Meanwhile the protium utilized can be shifted in aromatization become to be extremely limited, cause polycyclic aromatic hydrocarbons (PAH) etc. low
Hydrogen-carbon ratio product increases, and the dehydrogenation polymerization of polycyclic aromatic hydrocarbons (PAH) exacerbates catalyst coking.Currently, catalytic process is substantially
Sacrifice refined biological oil yield premise on promoted fuel grade, and promoted degree it is relatively limited (Castello D, He SB,
Ruiz MP,et al.Is it possible to increase the oil yield of catalytic pyrolysis
Of biomass A study using commercially-available acid and basic catalysts in
ex-situ and in-situ modus.Journal of Analytical and Applied Pyrolysis,2019,
137:77-85).In pyrolysis gas of biomass and the presence of moisture seriously affects conversion process in catalysate and product separation mentions
It is pure, if can individually dissociate the moisture in pyrolysis gas, more protiums can be not only provided for catalytic reforming reaction, improve essence
Biological oil yield and grade are made, and high energy electron generated, energetic free radical are living for activating and keeping catalyst surface
Property site play the role of it is positive, be conducive to inhibit catalyst coking.Currently, research there is no research or patent to propose to utilize moisture
The method that son participates in conversion process.
Microwave radiation is a kind of effective technology means that nonequilibrium plasma is generated using microwave, to specific gas molecule
Dissociation degree with higher generates up to 10000 DEG C of electronics and ion (Su under the premise of keeping original gas temperature
L,Kumar R,Ogungbesan B,et al.Experimental investigation of gas heating and
dissociation in a microwave plasma torch at atmospheric pressure[J].Energy
Conversion and Management,2014,78:695-703).Hydrone category polar molecule, dielectric constant is larger, is situated between
Matter loss factor is very high, has stronger absorbability to microwave, and the organic matters such as carbohydrate, methane, ethylene belong to mostly
In nonpolar molecule, dielectric constant is smaller, (Vesel A, Mozetic M, Drenik more much smaller than water to the absorbability of microwave
A,et al.Dissociation of CO2 molecules in microwave plasma[J].Chemical
Physics,2011,382(1-3):127-131).Therefore, microwave radiation is carried out to pyrolysis gas of biomass, can be more likely to dissociate
Hydrone therein, the electronics and ion energy of generation are enough to generate series of chemical, and gas temperature is then not too high,
Cause a large amount of decomposition of organic matter.Existing document report utilizes gas of the microwave radiation processing containing NO, H2O isopolarity molecule, meeting
It is allowed to part dissociation, excitation etc., generates active ion N free radical, O free radical, H free radical, OH free radical and high energy electron
Deng (Dalian research [D] of Tang Junwang conversion of NO with Microwave Irradiation: Dalian Inst of Chemicophysics, Chinese Academy of Sciences, 2001).
Currently, the technology is in the online catalysis upgrading research field of bio oil there is not yet document report.
