Abstract
Base catalysis method：It is catalyst with sodium hydroxide or potassium hydroxide, this is current most common preparation method, vegetable fat is reacted with methanol with transesterification (lactide), and sodium hydroxide (the 1% of grease weight) or sodium methoxide are used as catalyst, reaction 2 hours is about mixed, you can biodiesel synthesis.
Description
Technical field
The present invention relates to the biodiesel technology fields of alternative petrifaction diesel, and in particular to a kind of biodiesel synthesis and
Its technical method.
Invention content
A kind of base catalysis method biodiesel synthesis
Biodiesel, also known as fatty acid methyl ester are given up with fruit seeds flora conduits milk or animal tallow oil
Edible oil abandoned etc. makees raw material, is obtained with alcohols (methanol ethyl alcohol) through Transesterification.Biodiesel synthesis refers to using all kinds of
Animal and plant fat is raw material, is modified with alcohols materials such as methanol or ethyl alcohol by friendship esterification reaction, it is made to ultimately become for Inner
A kind of fuel that combustion engine uses.Biodiesel has some clear superiorities, and sulfur content is low, can reduce by about 30% sulfur dioxide
With the discharge of sulfide；Biodiesel has preferable greasy property, can reduce the mill of injection pump, engine cylinder body and connecting rod
Damage, extends its service life；Biodiesel has good fuel performance, and the safety used etc. in transport storages
Property is better than petrifaction diesel.In addition, biodiesel is a kind of regenerative resource and a kind of higher energy of degradability.It uses
Biodiesel can reduce CO2 emission and the discharge of air pollutants.
Background technology
A kind of base catalysis method biodiesel synthesis
For biodiesel oil product characteristic compared with common diesel, biodiesel has incomparable performance.(1) have excellent
Good environmental protection characteristic.It is mainly manifested in since sulfur content is low in biodiesel so that the discharge of sulfur dioxide and sulfide is low, can
Reduce by about 30% (being 70% when having catalyst)；The aromatic series alkane that can be polluted to environment is free of in biodiesel, thus
Exhaust gas is to human body damage less than petrifaction diesel.Detection shows compared with ordinary diesel oil, and 90% sky can be reduced using biodiesel
Gas toxicity, the trouble for reducing by 94% hinder rate；Due to biodiesel oxygen content height, make few, the discharge of carbon monoxide of discharging fume during its burning
Reduce by about 10% (being 95% when having catalyst) compared with diesel oil；The biological degradability of biodiesel is high.(2) have preferable
Cryogenic engine startability.Additive-free cold filter plugging point reaches -20 DEG C.(3) there is preferable greasy property.Mobilize injection pump
The low wear rate of machine cylinder body and connecting rod, service life are long.(4) there is preferable security performance.Due to flash-point height, biodiesel
It is not belonging to dangerous material.Therefore, it is obvious in transport having for use aspects of storage.(5) have good fuel
Energy.Cetane number is high, its flammability is made to be better than diesel oil, and combustion residue makes the use of catalyst and engine motor oil in subacidity
Service life lengthens.(6) there is renewable performance.As regenerative resource, its different from petroleum reserves passes through agricultural and bioscience
The effort of family, can supply will not be exhausted.In summary：Since the carbon dioxide discharged when biodiesel is burnt is far below the plant
Carbon dioxide absorbed in object growth course, so as to improve caused by the discharge of carbon dioxide global warming this have
Evil is in the great environmental problem of the mankind.Thus biodiesel is a kind of real green diesel.As regenerative resource, with petrochemical industry
It is oily different, can be by strengthening developing agricultural, raw material supply is guaranteed, and price is relatively stablized.Oil crops volume increase space is big, adds
Transgenic technology oil plant oil-containing can be made to have certain room for price-cut up to 70% or so.By OPEC, (oil is not defeated for fuel oil supply
Go abroad tissue) control, be more advantageous to the stability and development in international fuel oil market.Meanwhile the discharge of waste oil is reduced, mitigate dirty
The pressure and cost of water process.Waste cooking oil is converted, people's health is ensured, so as to have the function that double environmental protection.
Specific embodiment
A kind of base catalysis method biodiesel synthesis
Base catalysis method：It is catalyst with sodium hydroxide or potassium hydroxide, this is current most common preparation method, by plant
Grease is reacted with methanol with transesterification (lactide), and uses sodium hydroxide (the 1% of grease weight) or sodium methoxide as catalysis
Reaction 2 hours is about mixed, you can biodiesel synthesis in agent.
