Biodiesel Machine Pollute control to strengthen motor vehicle to discharge further, improve air quality, according to ” Beijing 2013-2017 year clean air operation plans ” , ” Beijing ferry hopes measure of aggrandizement of air pollution prevention and cure (2016-2017 year) ” requirement, beijing will use fuel level at car of the 6th phase is being carried out since January 1, 2017.
After predicting to use oil of the 6th phase to taste, discharging with content of benzine car grain fall amount to 10% , organic gas and azotic oxide can achieve blame firedamp on the whole of 8-12% discharge cut down rate; to be in drop with oxide of derv car nitrogen 4.6% , grain matter drops 9.1% , total hydrocarbon drops 8.3% , carbon monoxide drops 2.2% .
Ceaseless improvement car uses fuel character is one of important step that reduce motor vehicle pollution to discharge. The car uses fuel character rise not only use what ensure new car normally, still can raise purifier to change efficiency, make discharging synchronism to be cut down considerably with the car entirely. Our city 2004, 2005, 2008, took the lead in carrying out in the whole nation 2012 the 2nd, 3, 4 taste a standard with oil of 5 phase place.
Level the land Jing thunder, oil is tasted upgrade to greet strong voice again, beijing 6 levels are strong release, comparative and active Beijing standard of 5 steam derv, be in newest Beijing in 6 standards, motor gasoline, car shares 8 large window with derv, and give about the it may be said of 4 large window of derv standard replace the sources of energy to grow turning point. Did the spring that replaces the sources of energy come?
Among the standard to multinomial index gives more strict requirement in derv, concrete analysis comes under:
One, the index requirement of new standard and experiment method:
2, the content of much annulus aromatic hydrocarbon, by the country of 5 standards do not be more than 11%(quality mark) add severe to not be more than) of 7%(quality mark. Much annulus aromatic hydrocarbon has chemistry to send the cancerous sex, smooth effect that cause poison to wait, have very strong send abnormal, cause cancer, cause choppy effect. Aromatic hydrocarbon of the many annulus in derv can raise blaze temperature, increase azotic oxide thereby (of NOx) build quantity and discharge capacity, because this is necessary,limit the content of aromatic hydrocarbon of the many annulus in derv.
3, kosher agent is added in derv. Jam to reduce nozzle, preparation adds kosher agent in derv, can rise to restrain or remove the effect with engine nozzle anxious knot.
4, the change that tastes refine craft according to oil, the index such as viscosity of the density that uses diesel oil to the car, motion, flash point undertakes adjustment. Modification density (20 ¡æ ) “5 date, 0, – it is 820 Kg/m3 ¡« 10 numbers 845kg/m3, – 20, – 35 revise athletic viscosity for 840kg/m3”; of 800 Kg/m3 ¡« (20 ¡æ ) “5 date, it is 7.5 Mm2/s of 2.5 Mm2/s ¡« 0 numbers, – 10, – 20 are 7.5 Mm2/s of 2.0 Mm2/s ¡« , – 35 revise flash point for 6.5 Mm2/s”; of 1.5 Mm2/s ¡« (close a mouth) “5 date, 0, – 10 are not under 60 ¡æ , – 20, – 35 are not under 55 ¡æ ” . #p#·ÖÒ³±êÌâ#e#
5, the technical requirement that raises B5 car to use diesel oil and experiment method. This sets a of derv of good home live thing to ability is most immediate profit. Describe among the regulation: To press the application of biology derv steadily, on the foundation of referenced and existing GB, link demand of 6 phase index, diesel oil is used in this car B5 car increased to use diesel oil in the standard (the harmonic fuel of 1%~5% biology derv and 95%~99% oil diesel oil) technical requirement and experiment method, applicable inside certain limits. 6 standards car uses capital derv it may be said gives current progress low cardiac of confused potion of biology derv industry.
At present development of industry of derv of our country biology encounters raw material purchases segment of difficult, production not to have allowance, downstream sale channel out-of-the-way wait for defect, selling segment downstream among them is the problem that restricts industrial development directly. The standard that B5 alluded to mix mix into in this standard has bigger impact sense to business development. From the point of data, consumption of apparent of Beijing annual derv was 1.95 million tons about 2015, if press the scale of 5% to mix mix into to look, the demand of its biology derv is ninety-seven thousand five hundred tons, and crop of derv of annual country live thing was 450 thousand tons merely 2015, 21.6% what the demand of odd Beijing takes the throughout the country. If second standard whole nation applies, so the demand breach of countrywide biology derv is as high as 8.5 million tons / year, biology derv industry will greet the turn of milepost type.
But B5 standard was not tagged to mix mix into compulsively among the regulation at present, just allude applicable inside certain limits, because how this later period comes,answer to need to returning more the regulation of detail.
At the same time a bit more notable place is, adding biology diesel oil in allude, make oily development trend considering coal, coal introduces to make the idea that takes a car to use diesel oil in “ limits ” , suggest this standard applies to long instead “ press car of engine of derv burning type to use, make by oil take, coal is made take or add the car that improves performance characteristics additive uses diesel oil, also apply to the car that serves as concoctive constituent with biology derv to use derv ” . Because this makes oily industry tell to coal, future as derv standard upgrade, coal makes derv also will join the procession of GB main forces, just made relevant provision on scope of application, to at present our country coal makes oily trade and character also has bigger effect. Little oil of our country rich coal, coal makes oily industry face the situation with cost usury small profit at present, its sale also is harmonic domain more, later period has this special provision, give to downstream sale prop up, industrial catenary also will get the biggest those who change is perfect. deeper administrative levels also will help strength somewhat to the transition of structure of the sources of energy of our country. #p#·ÖÒ³±êÌâ#e#
