Abstract
The invention discloses a kind of method of effumability flammable liquid heating-value determination, this method operation is as follows：（1）100 mesh are made in coal quality granular activated carbon, when 150 DEG C of drying 2 are small, its calorific value is measured with microcomputer automatic calorimeter according to GB/T 213 2008；（2）A certain amount of activated carbon is weighed in crucible, flammable liquid is drawn with syringe or dropper, is added drop-wise on the activated carbon in crucible, its calorific value is measured with microcomputer automatic calorimeter according to GB/T 213 2008；（3）The difference for measuring calorific value twice is effumability flammable liquid calorific value.The present invention utilizes the strong absorption property of activated carbon, is measured after effumability flammable liquid is adsorbed according to coal sample caloric value, the method is easy to operate.Effumability flammable liquid after being tightly held by activated carbon is not volatile, reduce because sample volatilization and caused by detection error.After effumability flammable liquid is tightly held by activated carbon, flameholding, it is not easy to produce deflagration phenomenon, detection is more stable.
Description
Technical field
The present invention relates to a kind of assay method of effumability flammable liquid calorific value, test method are easy, easy to operate and accurate
Exactness is high.
Background technology
The measure of solid fuel calorific value is flammable for effumability generally using tabletting or directly to being measured as former state
For liquid, its mobility is big, and many effumability flammable liquids have volatility, it is impossible to using identical with solid fuel
Method is measured its calorific value.Country puts into exploitation and research of the substantial amounts of fund application in new energy at present, as new energy
The effumability flammable liquid in source, either in terms of the heat management or in terms of calculating the efficiency of internal combustion engine, is required for knowing it
Calorific value.But effumability flammable liquid calorific value is according to GB 384-1981 at present《Oil product heating-value determination method》Carry out
Measure, this method operation sequence is cumbersome, complicated, in order to avoid effumability flammable liquid in detection process volatilization loss,
Detection will prepare the material of sealed sample early period, take a considerable amount of time.In aerobic process, as oxygenate pressure fluctuates,
The rupture of approved sample film is be easy to cause, sample volatilization, causes testing result error larger.In view of the above problems, one kind can be developed
The method for fast and accurately testing effumability flammable liquid calorific value is extremely urgent.
The content of the invention
In order to overcome the shortcomings of that existing method tests effumability flammable liquid calorific value, the present invention provides a kind of volatile
The assay method of property flammable liquid calorific value, this method is easy to operate, using the strong adsorption capacity of activated carbon by effumability flammable liquid
It is detected after absorption, avoids evaporating, improves accuracy.
In order to reach the purpose of the present invention, using following technical scheme.
A kind of assay method of volatile flammable liquid fuel value, comprises the following steps：
（1）100 mesh are made in coal quality granular activated carbon, when 150 DEG C of drying 2 are small, according to the method in GB/T213-2008, are used
Microcomputer automatic calorimeter measures its calorific value；
（2）The activated carbon of certain mass is weighed in crucible, a certain amount of effumability flammable liquid is drawn with syringe or dropper
Body, is added drop-wise on the activated carbon in crucible, its calorific value is measured with microcomputer automatic calorimeter according to GB/T 213-2008；
（3）The difference for measuring calorific value twice is the calorific value of effumability flammable liquid.
The quality of the activated carbon is 0.9000 ~ 1.1000g, effumability flammable liquid quality for 0.2000 ~
0.4000g。
The present invention measures its calorific value after effumability flammable liquid is adsorbed using activated carbon strong adsorption capacity, prevents from easily waving
The flammable liquid volatilization of hair property causes detection error, and flameholding, is not likely to produce deflagration phenomenon.
The beneficial effects of the invention are as follows：
1st, activated carbon has highly developed pore structure and huge internal surface area, has very strong adsorption energy using activated carbon
Power is detected after effumability flammable liquid is adsorbed, and avoids effumability liquid volatilization loss in detection process；
2nd, activated carbon combustion process is stablized, and effumability flammable liquid also becomes stable by absorption after-combustion process, will not produce again
Raw deflagration phenomenon, greatly reduces repetition detection process, improves detection speed and accuracy.
