Abstract

The invention belongs to the field of clean fuels, and particularly relates to a compound additive for reducing saturated vapor pressure of methanol gasoline, and a preparation method for the compound additive, and application of the compound additive to preparation of M15-M25 methanol gasoline. The compound additive for the methanol gasoline consists of cosolvent, a dispersion stabilizer, a power accelerator, a vapor pressure adjustment inhibitor, a rubber swelling inhibitor, and a metal corrosion inhibitor in a selected weight part ratio. The compound additive for the methanol gasoline can effectively reduce the saturated vapor pressure of the methanol gasoline; even the compound additive is used in summer, the relative specification can also be met, the phenomenon of air resistance is avoided, and the technical problem that the methanol gasoline in a low proportion produces air resistance possibly in high-temperature summer, and cannot be supplied smoothly can be completely solved.

Description

technical field [0001] The invention belongs to the field of clean fuels, and in particular relates to a composite additive for reducing the saturated vapor pressure of methanol gasoline, a preparation method thereof, and an application thereof for preparing M15-M25 methanol gasoline. Background technique [0002] With the rapid development of my country's modern economy, car ownership is increasing year by year. Because automobile fuel mainly comes from petroleum products, its consumption is more than 70% of petroleum production, petroleum reserves are decreasing year by year, leading to the gradual depletion of petroleum resources, and the contradiction between supply and demand of petroleum is becoming increasingly prominent. China's current dependence on oil imports has exceeded 50%, and energy is in an unsafe state. Energy and environmental issues have become major issues restricting social and economic development. Therefore, the search for alternative energy sources...
