What about environmentally friendly fuel oil?

Environmental protection fuel oil is divided into two types:

One of them is the most alcohol-based fuel on the market, which is methanol fuel. Although it is also environmentally friendly, flammable and non-explosive, it is dangerous. Its flash point is not higher than 60 degrees, its calorific value is low, and it is not flame-resistant. You need to apply for relevant certificates of hazardous chemicals before you can legally produce them. It is impossible to do this at present, and the country is cracking down on it. The use of methanol fuel has been banned in many places.

The other is alcohol-free fuel, which is less on the market now. It is environmentally friendly and not dangerous. You can sell it with a business license. It has the advantages of burning resistance, high calorific value, considerable profit and good market prospect.

I also made methanol. There is no market now. I can't get the certificate.
