Is the ban on MTBE a problem with MTBE or a need to consume old grain?

This post was last edited by someone on 2019-10-17 20:48. I just saw a book translated by Hua Wei called "Fischer-Tropsch Refining Technology". The original book is "Fischer-Tropsch Refining". It mentioned the game process between MTBE and ethanol as oil additives in the United States. Technically, MTBE is better than ethanol. ； But some politicians in the United States support the addition of corn ethanol and lobby for it. “Because underground storage tank equipment is not mandated by law, storage tank leakage accidents cause MTBE to seep into groundwater. In 1999, politicians pushed hard to ban the use of MTBE in motor gasoline, and MTBE was banned from motor gasoline within a short period of time." I have always been confused before. It is said that MTBE is banned in the United States because MTBE pollutes groundwater. However, if chemical products are not well controlled, they can easily cause pollution. This is obvious. If the use of MTBE is banned, wouldn't it cause choking and waste of food? Even if we do this, what other chemical products are not banned? Oil spills also pollute! After reading this, I realized that the ban on MTBE in the United States was due to political demand, but MTBE has not been banned in Europe. It seems that Europe does not have as large a food production volume as the United States. So the question is, is the ban on the use of MTBE in our country also a demand in this regard, rather than technological progress?
Will my country ban the addition of MTBE to gasoline starting next year?
I don’t know, I heard it is, but the search only found that ethanol gasoline will be fully promoted in 2020. In fact, I feel that MTBE is not banned, because the national standard only limits the oxygen content and does not say that MTBE is banned. However, if ethanol gasoline is fully promoted, MTBE will definitely be restricted.
Ethanol gasoline for cars* * Standard regulations are not allowed. Other oxygenated compounds, MTBE is just one of them, cannot exceed 0.5%. However, if it is based on automotive gasoline * * Standard, add ethanol at the same time, such as 2-3%, and then add a certain amount of MTBE. This kind of oil does not belong to ethanol gasoline, as long as the total oxygen content does not exceed 2.7%, it is OK.
MTBE is a very good gasoline additive component because of its good miscibility with gasoline, high octane number, moderate vapor pressure, and higher calorific value than other methanol and ethanol, without significantly reducing the calorific value of gasoline. The ban on adding MTBE in the United States is purely due to political and grain export restrictions. China has also followed the trend in the past few years and shouted to ban or minimize the addition of MTBE. I personally feel that first, some authorities do not understand the necessity of MTBE as a gasoline component, and second, they are misled by some foreign research reports with political leanings. The biological toxicity of MTBE is much less than that of triphenyl. Reformate gasoline is used as a large amount of gasoline components, but MTBE is restricted, which is pure ignorance.
There is not enough food to eat, how can we get old food?
Importing food does not mean there is not enough food to eat, and besides, you are not hungry. * * A portion of the grain reserves will be rotated out every year, and new grains will be replenished. This amount is not small.
I also think banning MTBE is unreasonable
COFCO now has factories that produce ethanol from aged grains.
The poster said that the United States has it, and we can import it to help the United States digest it.
This is your own imagination, I never said that
