generally, it is liquefied gas, natural gas and methanol. Methanol products are still good, but for the current national control over hazardous chemicals, methanol is still a good product in the industry. So methanol can be done now, but the documents are not so easy at present. At present, alcohol-free is hot in the industry, and the products are not only dangerous chemicals, but also can save fuel costs for restaurant owners who use methanol and liquefied gas while operating legally.

And the profit is considerable. The cost and freight input is 2.5, and the market price is 4.5-1 kg in 5 yuan. The burning resistance is equivalent to that of liquefied gas, which saves fuel costs for restaurants from the unit price. Compared with methanol, the burning resistance is twice or more. One kg is equivalent to 2 kg of methanol burning, which can save restaurants, and the profit is 1,511-2,111 per ton. Ten restaurants are promoted every month, and one household has 511 kg. And restaurants will always overlap, not step by step.
