Abstract
The invention discloses fatty acid methyl ester which is prepared by using tung oil as a production raw material in a one-step process. During preparation, acid does not participate in reaction, and the fatty acid methyl ester is prepared by directly using an alkali catalyst (the content of KOH is 75-90 percent) in one step, thereby enlarging the application range of the tung oil and increasing the economic value of the tung oil. The fatty acid methyl ester prepared by using the tung oil as the raw material is relatively insensitive to humidity, high in stability, chemical corrosion resistance, electrical performance and mechanical performance, high in stability of products and clear and transparent; the pollution to the environment is avoided in the whole preparation process.
Description
Technical field
The present invention relates to fatty acid methyl ester processing technique field, also relate to a kind of biofuel and preparation method thereof.
Background technology
Heyuan mountain area has been distributed with a large amount of maniocas, account for whole mountain ridge area approximately 32%, tung oil is exactly the grease that the fruit of oily seeds manioca squeezes, because contain toxin in manioca seed, can not bring domestic animals such as feeding cattle and sheep chicken, so cause the manioca fruit of annual 3-4 season maturation all in the ground rotten, cause the very large wasting of resources, this method has been widened the use range of manioca fruit, rationally uses resource, more can increase farmers' income.
Summary of the invention
The present invention, provides a kind of long-term fatty acid methyl ester of stablizing taking tung oil as raw material, have good chemical resistance and have good electrical property and mechanical property.
Major equipment: 1 squeezing machine 2 whizzers 3 are processed cylinder 4 reaction cylinder 5 pretipitatin jars in earlier stage
Method:
The tung oil tree fruit of harvesting is squeezed through squeezing machine, and whole process is physical method, and the oil pressure in fruit is squeezed out.
With whizzer by solid-liquid separation, obtain the raw material Oleum Verniciae fordii that purity is higher, be 11 mg KOH/g-13 mg KOH/g through the detection tung oil acid number in laboratory, just just can use " single stage method " alkaline process fatty acid methyl ester processed that I announce to replace current " two-step approach " (acid-base method) at acid number lower than 13 mg KOH/g.In reaction cylinder, react, proportioning 85:18:2(is tung oil 85%: methyl alcohol 18%: KOH2%) temperature is controlled at 60 DEG C, and the reaction times is 90 minutes, just obtains approaching the fatty acid methyl ester of reactivity 99%.
Transesterification reaction finishes rear recovery methyl alcohol, realizes the recovery of methyl alcohol by standing or centrifugal mode, can continue to serve as the catalyzer of esterification or transesterify after being dried, and catalyzer must be used and recycle.
This result of study " is utilized the vegetable and animals oils of low-quality, quick and green production fatty acid methyl ester " provides a kind of new method.
Use " single stage method " to produce fatty acid methyl ester compared with traditional " two-step approach " adopting, two-step approach production process complexity, perishable production unit, the biofuel relative stability of producing is poor, and exist catalyzer difficult to reclaim, byproduct amounts of glycerol is large, refining is difficult, subsequent disposal produces the problems such as a large amount of waste water.So using " single stage method " to expand its use range for manioca fruit is a good method.
The present invention fills a prescription rationally, uses the method for simple and fast, and manioca fruit is converted into fatty acid methyl ester, preparation method's practicality, and popularized type is strong.
Claims (4)
