wholesale Biodiesel Production Line The distinction of biology derv and common derv
The definition of 1. biology derv and common derv
Biology derv: It is to show with oil-bearing crops, wild unboiled oil makings plant is mixed the fuel of derv of second birth sex of the oil of rubbish of the hydrophyte grease such as project small alga and animal fat, meal replaceable petrifaction derv that exchanges craft to be made through ester for feedstock oil. The odd alkyl ester that it is fatty acid of a kind of when raw material uses the technology such as hot splitting decomposition to get long chain. Biology derv itself contains oxygen to measure the mixture of extremely high complex and organic class status.
Derv: Weigh oil residue again, it is a kind of after oil is abstracted oleaginous child. It mixes composition by different hydrocarbon. Its bases is to contain 9 to 18 carbon atomic catenary alkyl, cycloalkanes or aromatic hydrocarbon. Its chemistry and physical character are located in between benzine and heavy oil, boiling point comes in 170 ¡æ between 390 ¡æ , specific gravity is 0.82~0.845kg/l.
2. basically distinguishs classification
Energy:
The calorific value of common derv is 35.5MJ/L, 16 alkyl value is 50 (standard) ; Biology derv calorific value is 32.4 ¡« 36.7MJ/L, 16 alkyl value is 5 ¡« 70. Although biology derv calorific value is a bit low, but its 16 alkyl cost is high, and oxygen is contained in biology derv composition, the combustion when mixing with common derv is more complete, thermal efficiency is taller, so, mix use can obtain good dynamical sex, can achieve those who use diesel oil most high-power, have good excess load character.
Environmental pollution:
Compare with common derv photograph, discharge capacity of poisonous and organic matter is only in the car tail gas that uses biology diesel oil 10% , grain content is only 20% , carbon monoxide discharge capacity (when having activator) can decrease 95% , wait for what toxicant pledges to discharge without 2 oxidation sulfur and lead.
Property:
The property of biology derv and common derv are very adjacent. Like athletic viscosity common derv is 3 ¡« 8, biology derv is 5 ¡« 10, be used alone or mix by any scale mix into with derv use, all need not make any altering to engine and oil path, divide separate use perception motive force is a bit small outside, mix under 50% mix into use extremely why to distinguish damage with common derv: Do not have to engine, oil path corrode, nozzle does not have a knot anxious, firebox does not have carbon deposit. Have good lubricant performance, make cylinder body of fuel injection pump, engine and connecting rod wear rate are reduced.
Security:
Biology derv because flash point is high, do not belong to danger to taste, store, carry, use relatively safe. Compare with groovy derv photograph, biology derv has undermentioned the performance that cannot compare:
3.Biology derv after all can is sheet burned?
According to small make up understanding, in derv of domestic live thing all be mediate with certain proportion and petrifaction derv use, this kind of method can reduce oily cost, raise dynamical sex, reduce tail gas pollution. The good performance of biology derv makes the index of engine exhaust emission that uses biology diesel oil satisfies level of current European II number not only, contented even be about to promulgate executive more firm European ¢ó order to discharge a standard in Europe subsequently. And the carbon dioxide that when burning as a result of biology derv, discharges is far grow under this plant the carbon dioxide that absorbs in the process, because the discharge and brings about whole world of carbon dioxide is calefacient,improve thereby the great environment problem of mankind of this one deleterious. #p#·ÖÒ³±êÌâ#e#
In light of summary, if biology derv serves as the word of diesel engine fuel to have some of corrupt practice really directly, its have certain effect to engine, because give birth to matter diesel oil,want than common derv density and exterior tension tall, heat up in a steamer divides heavier, narrower, volatility taller, especially viscosity wants than common derv bigger. Biology derv viscosity is 3.5~5.0 Mm2/s commonly, the viscosity tower above that compares common derv 2.0~3.5 Mm2/s makes an appointment with 15%~75% . Because this will form bigger small droplet from fuel nozzle pulverization, make pulverization becomes poor. Because this uses biology diesel oil, phenomenon of will easier occurrence incomplete combustion, proposal and petrifaction derv are at present harmonic use, but as the technology more and more advanced, derv of later period biology realizes perfect sheet to burn also be not impossible.
