Raise, aromatic carbon ratio is continuously increased, when 525 DEG C, only remain substantially aromatic carbon structure (EC)
It can be seen from the results above that the EC catalytic hydrogenation separation temperature of the sample is 525 DEG C.
Due to there is no obvious boundary (Chow et al., 2001) in carbonaceous aerosol between organic carbon and black carbon, and
Completely organic carbon can not be separated from black carbon and will directly affect the accuracy of 14C measurement result in black carbon.With commonly used at present
From the point of view of carbonaceous aerosol analysis method, the preprocess method for doing 14C analysis in preparation carbon source has weak point.Optical method is logical
Cross the light absorptive of BC to determine the content of BC in aerosol, it is impossible to for the pretreatment of 14C analysis.Thermophotometry be using black carbon
Light absorptive and heat endurance are determining the black carbon in carbonaceous aerosol.Method be by entering line program to quartz filter sample stripping and slicing
Rise gentle oxidizing atmosphere to contain system to obtain the concentration of black carbon (also referred to as elemental carbon), for anaerobic heating period part organic carbon
" charing " be by through filter membrane (TOT) or from filter membrane surface reflection (TOR) laser signal monitor sample blackness change and
It is corrected (as " laser-adjusting ")；Due to temperature program(me) and the difference of laser-adjusting principle etc., it is black that two methods are obtained
Carbon result often has difference (Chow et al., 2001) more than twice.Due to there is Laser corrective in thermophotometry so that separate OC
14C is carried out with BC and determine operation easier greatly, the document that there is presently no correlation shows that the technology is applied in 14C measure.Change
Method is to determine one of conventional means of black carbon 14C, but the method is due to the reason such as formality is loaded down with trivial details and speed is slower, in aerosol
The use in field has been reduced, but still has the use of suitable scope, supplementary means (the such as pre- place especially as other methods
Reason), to increase the accuracy of other methods.Recently, heat chemistry oxidizing process (CTO-375, chemothermal oxidation
Method) research for determining that black carbon content and the black carbon of purifying in aerosol survey 14C is applied to.Aerosol sample is placed on 375
DEG C stove in 18 hours, blowing air is organic oxidation of coal, remaining for black carbon.The black carbon tool that the method is generated to some high temperature
There is good comparativity, but to the black carbon that some low temperature are generated, then its result difference is larger, up to tens times (Hammers et
Al., 2007), meanwhile, in its oxidizing process, oxidized fall part (non-black carbon part) can not collect and continue to analyze, sample
Waste serious.Even so, the method be determine at present the black carbon 14C of carbonaceous aerosol main method (Sun et al.,
2012).
Catalytic hydrogenation method is under high pressure hydrogen stream mode (15MPa), carries out temperature programming with molybdenum sulfide as catalyst and splits
Solution experiment, in order to separate Stable Carbon and unstable carbon component in sample.Hydrogenation catalyst cracking technique is by coal distillation/cracking experiment
Introduce in research, the addition by hydrogen in reaction system is improving products collection efficiency.It is natural that the method was introduced in oil later
In gas geochemical investigation, in order to improve the relative productivity for obtaining biomarker.Experiment shows that the cracking of catalytic hydrogenation method is non-black
Carbons organic matter yield is high, the little advantage of molecule heat etching change effect in experimentation (Zhou Jianwei, etc. 2006).Recently, the method
In terms of being successfully applied geochronology, Ascough et al. has been successfully separated standard sample of soil using Catalytic Hydrogenation Techniques and has sunk
Black carbon in product thing, determines the 14C activity in black carbon, the process such as its age dating result and other use for laboratory chemical methods
As a result have good comparativity, and the favorable reproducibility of sample.Therefore, Ascough etc. thinks, catalytic hydrogenation method be a kind of quick,
Reliable radioactive carbon analysis preprocess method (Ascough et al., 2009).But up to the present, also there is no related text
Offer in terms of illustrating that the method is applied to the research of carbonaceous aerosol.Compared with heat chemistry oxidizing process etc., catalytic hydrocracking process
It is unnecessary to obtain relatively pure black carbon and a part of black carbon of over oxidation.Result of study shows that catalytic hydrocracking process exists
500 DEG C can be converted into volatile organic matter (Rocha et al., 1999) lignocellulosic 100%；525-550 DEG C it
Between, its chemically inert difference different according to black carbon type, the chemical reaction platform under a different temperatures can be formed, accordingly
Judge whether catalytic hydrogenation is finished non-black carbons organic matter, determine organic carbon and black carbon line of demarcation (Ascough et al.,
2009).The feature of catalytic hydrogenation method is the optimization of the black carbon analysis method of carbonaceous aerosol there is provided possible.On the one hand, through catalysis
After hydrogenation, after organic carbon cracking, the organic matter of formation, is carried along into cold trap trapping device by high pressure hydrogen, and then quantitative analysis is organic
Carbon content and the activity of organic carbon 14C；On the other hand, catalytic hydrogenation is reduced organic carbon and is formed black carbon due to thermal cracking
Possibility, be analyze residue in black carbon and black carbon 14C reduce interference.
