The hottest year in 2020, the country will promote

In 2020, the country will promote ethanol gasoline for vehicles. Is it powerful enough and cheap

the vehicle ethanol gasoline mentioned here refers to adding 10% biofuel ethanol to gasoline. Ethanol is what we call alcohol in our daily life. At present, ethanol gasoline for vehicles is mainly promoted in 11 provinces in China, including Heilongjiang, Jilin, Liaoning, Anhui, Henan, Guangxi and other six provinces (regions) throughout the country. In addition, Guangdong, Shandong, Hubei, Hebei, Jiangsu and other five provinces are only promoted in 31 cities

what are the differences between ethanol gasoline and traditional gasoline? Will it be more environmentally friendly than traditional gasoline

insufficient power of vehicle ethanol gasoline

in the above-mentioned provinces that promote vehicle ethanol, many car owners do not like ethanol gasoline well, thinking that ethanol gasoline has poor power and high fuel consumption. Is this really the case

according to Zhang Yongguang, a professor senior engineer of Sinopec Academy of Sciences, in terms of calorific value, compared with ordinary gasoline, ethanol gasoline theoretically has a calorific value difference of about 3.8%. However, it cannot be said that it has lost 3.8% completely, because its octane number is higher than that of olefins and aromatics. Basically, it has more than a dozen octane number units, making up for the loss of fuel consumption of about 1%-2%, which can be better applied to the performance of vehicles with high compression ratio (engine). Ethanol gasoline itself contains oxygen, which promotes the combustion of gasoline. Some incompletely burned hydrocarbons have been burned better, which may make up for 1% to 2% from this point of view

"according to our previous research, ethanol gasoline is fully promoted in gas stations with three barrels of oil, and the rest of the time is invalid. But it is not in private gas stations, because consumers and customers think that ethanol gasoline is lack of power. In the words of ordinary people (49.040, -0.83, -1.66%), it is that the oil is added, the speed cannot be improved, and the driving is more meat." Zhuochuang Information Analyst huhuichun said in an interview

in addition to fuel consumption, the price of ethanol gasoline for vehicles is also a common concern of consumers. In 2016, the above-mentioned cities and prefectures that promote ethanol gasoline have issued a set of revised methods, that is, the sales price of ethanol gasoline for vehicles is implemented according to the price of ordinary gasoline with the same label, and the price is clearly marked

car injury caused by ethanol gasoline

as early as 2001, with the consent of the State Council, China launched a pilot project of biofuel ethanol. But the process was not smooth, largely because consumers could not accept it. In recent years, many we media have successively posted that some car owners are burning ethanol gasoline without knowing it, and said that the use of ethanol gasoline in cars will not only increase fuel consumption, but also seriously hurt the car. Will ethanol gasoline really hurt the car

first of all, because ethanol will produce acetic acid during combustion, it has a corrosive effect on automotive metals, especially copper. Relevant tests show that when the content of ethanol in gasoline is%, there is basically no corrosion to metals. However, when the ethanol content exceeds 15%, the corrosion effect will become obvious, and effective corrosion inhibitor must be added at this time

secondly, ethanol is also an excellent solvent. It can clean the dirt in the oil tank and pipeline (mainly the mixture of colloid and rust stains), but it is easy to cause slight corrosion, swelling, softening or cracking on the sealing rubber and other synthetic non-metallic materials of cars

however, the current situation in China is that ethanol gasoline is mixed with basic gasoline and ethanol, but the short shelf life of ethanol gasoline determines that ethanol gasoline cannot be produced and stored on a large scale, and can only be "cashed in" by various places. Therefore, we will encounter whether the ethanol proportion in ethanol gasoline is strictly added according to 10%

is ethanol gasoline more environmentally friendly

compared with ordinary gasoline, ethanol gasoline for vehicles is considered to be more environmentally friendly, and the pollutants caused by vehicle exhaust emissions are also lower. Because it contains 10% ethanol, carbon monoxide and carbon dioxide after combustion are much lower than ordinary gasoline

"because alcohol contains oxygen, it can burn completely, so hydrocarbon can also be greatly reduced. I think it is an environmentally friendly renewable energy." Qiao Yingbin, former director of Sinopec science and technology department and professor level senior engineer, said in an interview with CCTV

in addition to burning directly to reduce air pollution, vehicle ethanol gasoline is also crucial to the change of domestic energy demand structure. According to public data, as of 2016, China's dependence on crude oil has reached 65.4%. Under this background, actively promoting ethanol gasoline is conducive to the change of energy structure

according to the data of the national energy administration, by the end of 2016, the installed capacity of photovoltaic, wind power, hydropower and other renewable power has accounted for 34.6% of the total installed capacity of domestic power, and the consumption of renewable power has accounted for 25.4% of the total electricity consumption of the whole society, which has effectively promoted the continuous optimization of the domestic power supply structure. In contrast, the development of renewable liquid fuels in China is significantly lagging behind. The actual consumption in 2016 was only about 3million tons, less than 1% of the national refined oil consumption, which has become a prominent weakness in the current energy transformation and urgently needs to be accelerated

on the other hand, the fuel ethanol industry, which produces ethanol gasoline, is also one of the important means to digest excess corn, because its main raw materials are overdue corn and waste straw

"the fuel ethanol with corn as raw material can reduce the emission of about 34% per ton of ethanol. If cellulosic ethanol is commercialized and developed rapidly in 2025, the environmental protection benefit will be more obvious, which can reach more than 75%. Especially as a cellulosic ethanol industry, it should be said that it can effectively solve the problem of atmospheric pollution caused by straw incineration." Said leyouhua, deputy director of petrochemical light textile department of China International Engineering Consulting Corporation

according to the calculation of relevant authorities, China's annual over time and over standard grains can support a certain scale of biofuel ethanol production. In addition, the annual trade volume of corn and cassava in the international market reaches 170 million tons, and 5% can be converted into biofuel ethanol of nearly 3 million tons. More than 400 million tons of straw and forestry waste can be used in China every year, and 30% of them can produce 20million tons of biofuel ethanol. All these provide a reliable raw material guarantee for expanding the production and consumption of biofuel ethanol and achieving sustainable development

how to promote the promotion plan and how effective is it

in fact, this is not the first time that vehicle ethanol gasoline has appeared in the national government's plan. In February this year, the guidance on energy work in 2017 issued by the National Energy Administration mentioned that "the production scale and consumption area of biofuel ethanol should be moderately expanded"

seven months later, the country set specific goals

according to the requirements of this plan, the document requires all relevant units to moderately develop grain fuel ethanol, scientifically and reasonably grasp the total amount of grain fuel ethanol, and vigorously develop cellulose fuel ethanol and other advanced biological liquid fuels in accordance with the basic principles of "strictly controlling the total amount, diversified development", "standardizing the market, orderly circulation" and "promoting by law and encouraging by policies", Meet the growing market demand

in addition to promoting ethanol gasoline for vehicles nationwide by 2020, the plan also points out that by 2025, we will strive to achieve large-scale production of cellulosic ethanol, and the advanced bio liquid fuel technology, equipment and industry as a whole will reach the international leading level, forming a more perfect market-oriented operation "digital production system of composite materials" SABIC through cutting-edge technology and process mechanism

but there is no specific promotion plan and schedule in this plan. Li Li, director of anxins China research, believes that if it is popularized nationwide in 2020, the most extreme case will replace 15% of the gasoline market share, and the gasoline market will be divided up at least 20million tons. At the same time, for refined oil wholesale enterprises, the plan requires that biofuel ethanol should be purchased in time to ensure the supply of ethanol gasoline for vehicles in the market. This means that we have to study the issue of increasing the consumption tax on ethanol fuel

huhuichun also believes that in order to achieve the goals in the plan, the country still needs to do a lot of research in the follow-up, such as how to formulate relevant laws and regulations for bending samples, and whether there will be subsidy policies for vehicle ethanol gasoline
