The national standard diesel is fully delisted today and upgraded to the national standard
Starting from today, China's diesel market will fully implement the three national standards, and the country's second diesel standard will exit the stage of history. As the Guangdong region has already implemented Guosan Diesel, it will not be affected. From the standpoint of performance difference of the main indicators, the sulfur content will be reduced from 350ppm to 150ppm after the diesel is upgraded. Since January 1, 2015, the full implementation of diesel standards in the four countries, sulfur content further reduced to 50ppm. In addition, China's gasoline will be unified and upgraded by the end of this year to implement the four national standards (sulfur content in ≤ 50ppm), Guangzhou will take the lead in the next five gasoline.
Judging from the differences in the performance of the main indicators, Guodi Diesel requires a sulfur content of no more than 0.2%, and Guosan Automotive Diesel requires a sulfur content of no more than 0.035%. The reduction of sulfur content will directly reduce the emission of pollutants by about 50%.
At present, most refineries owned by PetroChina and Sinopec have already had the ability to produce the country's three diesel oils. On the sales side, most of the nation’s two-barrel oil retail sector had already been Guosan Diesel before, and only a few regions in the northwest were still the second country.
National five gasoline per liter increase in the 2 to 3 angle
It is reported that before the end of 2013, China will release the national standard for five-vehicle gasoline, and the transition period will be until the end of 2017.
At present, besides the implementation of Beijing Five-Standard gasoline (sulfur content ≤ 10ppm) in Beijing, and in some cities in Shanghai, Jiangsu, and Guangdong, the national standard gasoline (sulfur content ≤ 50ppm) has been implemented, and the remaining three regions have basically implemented the national standard gasoline (sulphur content). At ≤150ppm). With the advancement of replacement, Guangzhou, Shanghai, Jiangsu and other places will also be the first to use the national five gasoline. The citizens of Guangzhou will be the first to use the country's five gasolines next year. With the increase in the standard, the price of gasoline may rise again. The industry predicts that the increase per liter may be about 2 to 3 cents or so. "The spread per ton is around 300 yuan."
According to the news, China's gasoline will be upgraded and implemented at the end of this year. The National IV standard (sulfur content is ≤ 50ppm); at the end of 2017, all five national standards will be implemented.
It is understood that in order to tie in with product upgrades, PetroChina and some of Sinopec's subordinate refineries have actively cooperated and upgraded the installations accordingly. Industry sources pointed out that the reduction of sulfur content will directly reduce the emission of pollutants and improve the atmosphere; and it will reduce the damage of sulfur to the engine and prolong the service life of the engine.
