Today that stone fuel increasingly depleted and environment deteriorate increasingly becomes more and more important.Biomass pyrolysis oil (calling bio oil in the following text) conduct
A kind of primary fuel, in physics and chemistry properties, there are obvious shortcomings, it is necessary to it is modified it is refined, to improve the product of bio oil
Matter.Currently, refined method of modifying mainly has the methods of catalytic pyrolysis, catalytic hydrogenation and catalytic esterification, wherein catalytic pyrolysis is refined
Method security is higher, and reaction condition is relatively mild, by the extensive concern of domestic and foreign scholars.But traditional catalytic pyrolysis means
It has been difficult to the substantive upgrading efficiency for improving bio oil catalytic pyrolysis process.Lower temperature plasma technology mainly utilizes chemistry
The extremely strong high energy particle of activity and active specy participate in chemical reaction, complete insoluble problem under many conventional conditions.Closely
Nian Lai, this seminar take the lead in lower temperature plasma technology being combined with bio oil catalytic pyrolysis process, construct bio oil and urge
Change the low-temperature plasma synergistic catalysis of cracking（Non-thermal Plasma Synergistic Catalysis, NPSC）
System, the synergistic effect in NPSC systems between low temperature plasma and catalyst advantageously reduce catalyst burden, promote production
Object improves the selectivity of product and reduces product gathering on a catalyst in the desorption of catalyst surface（Coking）Phenomenon increases
Powerful catalyst stability.Compared with when HZSM-5 is individually catalyzed, NPSC systems make HZSM-5 coking rates be substantially reduced, and decrease by
63.61%, hydrocarbon content then further improves 13.81%, but wherein PAHs contributes to 5.68%（Zhao Weidong, Lai Zhihao, Cai
Recall former times, waits the online catalytic pyrolysis upgrading rape stalk pyrolysis oil chemistry of forest product of low-temperature plasma synergistics HZSM-5 and work
Industry, 2016,36 (6): 9-15.）.
From technique restraining factors angle analysis, the Deep Catalytic Cracking process of bio oil is mainly restricted by catalyst and raw material.
In terms of raw material, effective hydrogen-carbon ratio of biomass or bio oil（Hydrogen to Carbon Effective Ratio, (H/
C)eff）It is relatively low, belong to seriously scarce hydrogen feedstock, raw material (H/C)effConcept first by Chen etc.（Chen N Y, Degnan T
F, Koenig L R. Liquid fuel from carbohydrates. Chemical Technology, 1986, 16:
506-511.）It proposes.HZSM-5 molecular sieves are difficult to (H/C)effScarce hydrogen feedstock less than 1 carries out stable, lasting catalysis.Together
When, in default of the protium that can be efficiently used, aromatisation reforming reaction can turn in HZSM-5 molecular sieve catalytic cracking process
Moving the protium utilized becomes to be extremely limited, and the low hydrogen-carbon ratios product such as PAHs is caused to increase, and the further dehydrogenation polymerization of PAHs
The coking of molecular sieve is exacerbated again.After NPSC systems structure, the interaction between high energy active specy and active catalyst sites
HZSM-5 coking rates are made to be decreased obviously, but bio oil (H/C)effIt is relatively low, it can shift the protium utilized more in catalytic process
It is limited, cause the low hydrogen-carbon ratios product such as PAHs to increase, HZSM-5 still has certain coking rate.Therefore, by improving raw material (H/
C)effTo further enhance the anticoking capability of HZSM-5 in NPSC systems, and the substantive fuel quality for promoting bio oil, it is
Break through an important research thinking of deep catalytic cracking technology bottleneck.
