Problems solved by technology

[0002] Existing composite unleaded gasoline is generally composed of methanol, xylene, and solvent gasoline. This kind of composite unleaded gasoline has the following disadvantages: (1) When the temperature exceeds 45°C, the activity of methanol is enhanced, and it is easy to form a vapor flow, thereby generating gas. On the contrary, when the temperature is extremely low, the convergence of the composite unleaded gasoline increases, and the oil circuit is blocked, which makes it difficult to start
(2) Solvent gasoline is used as the main raw material. Due to the instability of various properties of solvent gasoline, the octane number fluctuates greatly, and sometimes knocking occurs
(3) Due to the generally high colloid content of solvent gasoline, the stability of compound gasoline is affected
(4) It is corrosive to a certain extent and will have a certain impact on the oil circuit
(5) When mixed with traditional gasoline, it is prone to stratification
But the cost of the improved compound unleaded gasoline is relatively high
