Description
Technical field
The present invention relates to a kind of manufacturing methods of biodiesel.
Background technology
Biodiesel worldwide develops very fast, and source is very extensive.Currently, Europe mainly with
Rapeseed oil is raw material, the U.S. mainly using soybean oil as raw material, India mainly using Jatropha curcus as raw material, and China mainly with
Waste grease is raw material.Shiny-leaved yellowhorn yield is big, and for oil content 30% or more, laboratory prepares biodiesel mainly with conventional homogeneous
Base catalyst, such as potassium hydroxide, various carbonate, sodium hydroxide are converted with mechanical agitation ester and one step conversion has synthesized life
Object diesel oil.There has been no researchs for the laboratory preparation of the biodiesel of shiny-leaved yellowhorn preparation at present.
Invention content
It is an object of the present invention to provide a kind of manufacturing methods of biodiesel, can be produced by the manufacturing method and meet state
The biodiesel of family's standard.
The present invention is realized by following technological means：
A kind of manufacturing method of biodiesel of the present invention, includes the following steps：
1) shiny-leaved yellowhorn seed is placed in drying box dry；
2) seed after drying is placed in hulling machine and is shelled；
3) seed after shelling is placed in oil press and is extracted oil；
4) oil squeezed out is placed in high pressure filter and is filtered；
5) the quantitative shinyleaf yellowhorn oil filtered, methanol and potassium hydroxide are placed in biodiesel and are reacted；
6) biodiesel of production, distilled water, glacial acetic acid are placed in converter, cycle mixing water is carried out by air pump
It washes, after washing, stratification releases lower water；
7) a certain amount of anhydrous sodium sulfate is added into the oil through washing, stirs standing separation, you can obtains clear
Biodiesel.
Further, the pressing temperature in step 3 selects 210 DEG C.
Further, it is 5: 1 that the reaction condition in step 5, which is molar ratio of methanol to oil, and the amount of catalyst potassium hydroxide is oil quality
2%, temperature be 60 DEG C, reaction time 4h.
Beneficial effects of the present invention：The manufacturing method of the biodiesel of the present invention, includes the following steps：1) shiny-leaved yellowhorn is set
In dry in drying box；2) seed after drying is placed in hulling machine and is shelled；3) seed after shelling is placed in oil press
Oil expression；4) oil squeezed out is placed in high pressure filter and is filtered；5) the quantitative shinyleaf yellowhorn oil filtered, methanol and potassium hydroxide are set
In being reacted in biodiesel；6) biodiesel of production, distilled water, glacial acetic acid are placed in converter, are carried out by air pump
Cycle mixing washing, after washing, stratification releases lower water；7) a certain amount of anhydrous sulphur is added into the oil through washing
Sour sodium stirs standing separation, you can obtains the biodiesel of clear.It can be produced by the manufacturing method and meet national mark
Accurate biodiesel.
Specific implementation mode
Below by way of specific embodiment to the detailed description of the invention：
A kind of manufacturing method of biodiesel of the present invention, includes the following steps：
1) dry, shiny-leaved yellowhorn seed is placed in drying box, temperature is set as 100 DEG C, forced air drying 4h.Its purpose is mainly
Dry kind of shell, makes it become fragile, convenient for shelling in next step.
2) it shells, the seed after drying is placed in hulling machine and is shelled, squeezed convenient for next step high temperature.
3) high temperature squeezes, and the seed after shelling is placed in oil press, is squeezed according to oil press operating procedure and oil expression main points
Oil, pressing temperature select 210 DEG C.Its principle is the protein denaturation made using high temperature in material embryo, to destroy the tissue of oil plant
Cell；Under press chamber condition of high voltage, oil is just overflowed from oily line.
4) it filters, the oil squeezed out is placed in high pressure filter and is filtered.This is to remove the machinery being suspended in crude oil
Impurity and part colloidal impurity.
5) it converts, the quantitative shinyleaf yellowhorn oil filtered, methanol and potassium hydroxide is placed in biodiesel；In step 5
Reaction condition is that molar ratio of methanol to oil is 5: 1, and the amount of catalyst potassium hydroxide is the 2% of oil quality, and temperature is 60 DEG C, the reaction time
For 4h.
6) it washes, the biodiesel of production, distilled water, glacial acetic acid is placed in converter, it is mixed to carry out cycle by air pump
It closes, washes 2 times, after washing every time, will release lower water after stratification.The effect of glacial acetic acid is to prevent water and oil
Emulsification, dosage be crude oil volume 0.3%, temperature be 65 DEG C, time 26min.The step is generated to remove dereaction
Soap-like matter and unreacted methanol.
7) dry, a certain amount of anhydrous sodium sulfate is added into the oil through washing, stirs standing separation, you can must clarify
Bright biodiesel.
The skilled worker of the industry is it should be appreciated that the present invention is not limited to the above embodiments, above-described embodiment and explanation
Being only intended to described in book illustrates the principle of the present invention, and under the premise of not departing from the principle of the invention and range, the present invention is also
There can be various changes and modifications, these changes and improvements belong in scope of the claimed invention.
