Background technology
Oil shale fuel is a kind of important emerging energy, C in shale 5~ C 14light hydrocarbon is the important component part of oil shale fuel, and its content not only determines the resource potential of shale oil gas, also determine the mobility of shale oil gas and can employ feature, C in addition 5~ C 14contain a large amount of geochemical informations in light hydrocarbon, the deficiency that other geochemical analysis methods exist can be made up.
Because traditional method for extracting can only obtain C in mud shale 15above hydrocarbon compound, to the research relative difficulty compared with light constituent in mud shale.2004, Southwest Petroleum Institute invented a kind of method (patent No. ZL 02113247.X) of extracting all hydrocarbons from hydrocarbon rock, obtains C in rock 1~ C 25the information of hydrocarbon component.The weak point of the method is: releasing in heat can be comparatively large because of sample particle diameter (30 order ~ 60 order) in process, and heavy component release not exclusively; Ask for the total hydrocarbon content in hydrocarbon source rock with weight method, total hydrocarbon content can be caused to be forbidden because of impurity, directly can not obtain the content of single component.2005, Petroleum Geology Institute experimental study center, exploratory development research institute of China Petrochemical Industry Wuxi have developed rock sealing hydrocarbon extraction instrument (patent No. ZL 02160133.X), obtains C in rock 6~ C 15the information of hydrocarbon component.The method can only be carried out by the restriction of environment temperature winter, uses freon extracting to there is environmental issue in experiment.2011, a kind of analytical approach and equipment (patent No. 200710119460.6) thereof of light fraction compounds in petroleum hydrocarbon source rock were invented by exploratory development research institute of PetroChina Company Limited., obtain C in rock 5~ C 13the information of hydrocarbon component.The weak point of the method is: heat is released temperature and only had 200 DEG C, n C 13boiling point 234 DEG C, can cause comparatively heavy hydrocarbon component remain; Can not be quantitative, on-line analysis can only carry out oil, rock comparative study.We have invented a kind of new mud shale heat for this reason and release C 5~ C 14the preparation of hydrocarbon and on-line chromatograph analytical approach, solve above technical matters.
Summary of the invention
The object of this invention is to provide one to have taken into account on-line chromatograph analysis and prepared sample for other analysis project, with the C that interior mark can be quantitatively residual in mud shale more accurately 5~ C 14the mud shale heat of hydrocarbon releases C 5~ C 14the preparation of hydrocarbon and on-line chromatograph analytical approach.
Object of the present invention realizes by following technical measures: mud shale heat releases C 5~ C 14the preparation of hydrocarbon and on-line chromatograph analytical approach, this mud shale heat releases C 5~ C 14preparation and the on-line chromatograph analytical approach of hydrocarbon comprise: step 1, after mud shale sample is ground to form particle, put into the quartz specimen boat of tubular furnace; Step 2, heated Tube-furnace under helium purge, the hydrocarbon component in sample is enriched in liquid nitrogen cold trap; And step 3, startup chromatograph after enrichment completes, Fast Heating on-line preconcentration pipe, heat is released hydrocarbon and is entered chromatographic column with carrier gas through high temperature six-way valve and be separated.
Object of the present invention also realizes by following technical measures:
In step 1, mud shale sample is ground to form 60 order ~ 80 object particles.
This mud shale heat releases C 5~ C 14preparation and the on-line chromatograph analytical approach of hydrocarbon also comprise, after step 1, on-line preconcentration pipe is immersed the liquid nitrogen in vacuum cup, collection tube is immersed the liquid nitrogen in vacuum cup, collection tube is connected to tubular furnace, high temperature six-way valve is connected to tubular furnace, chromatograph is connected to high temperature six-way valve, on-line preconcentration pipe is connected to high temperature six-way valve.
Step 3 also comprises, and takes off collection tube after enrichment completes, freezing for subsequent use after sealing.
In step 2, when heated Tube-furnace, heat releases temperature 280 DEG C, constant temperature 30min.
Chromatograph is Agilent 6890N gas chromatograph.
Mud shale heat in the present invention releases C 5~ C 14the preparation of hydrocarbon and on-line chromatograph analytical approach, overcome the large and heat of the sample particle that exists in prior art release temperature low heavy component is remained, quantitatively inaccurate, preparation and on-line analysis, the problem being unfavorable for environmental protection can not be taken into account.This method avoid the comparatively large or heat of sample particle to release the temperature heavy component heat caused on the low side and release not exclusively, taken into account on-line chromatograph analysis and prepared sample for other analysis project, the C that can remain in quantitative mud shale more accurately with interior mark 5~ C 14hydrocarbon, not only can carry out oil, rock comparative study but also can quantitative evaluation mud shale, convenient and environmental protection.Stratographic analysis result can be seen, the method effectively can obtain the C in mud shale 5~ C 14component.
