Methanol and gasoline mixed fuel oil and method for preparing same

Abstract

The mixed fuel oil has in its material mixed liquid of methanol and ammonium stearate and mixed liquid of gasoline and methyl tert-butyl ether. The production process includes pre-mixing methanol and ammonium stearate in certain proportion; pre-mixing gasoline and methyl tert-butyl ether in certain proportion; spray mixing the two kinds of pre-mixed liquid; letting stand and separating the mixed liquid to obtain the supernatant as the fuel oil product. The present invention has simple production process and high production efficiency, and the product can maintain its mixed state without laminating and separation, has power performance the same as that of the gasoline and good cold start performance and is suitable for use in machine using gasoline fuel.

Description

technical field [0001] The invention proposes a fuel in the chemical industry, specifically a methanol-gasoline blended fuel oil and a production method thereof. Background technique [0002] Before the present invention was proposed, there were fuel oil products formed by adding methanol to gasoline both at home and abroad. Its purpose is to add cheap and easy-to-get methanol to gasoline to reduce the price of fuel oil, reduce dependence on petroleum, and reduce the content of harmful substances in exhaust gas. However, since methanol is a water-soluble substance, it is easy to mix with water during the process of miscibility with gasoline and during storage, so that methanol and gasoline are separated, which affects the performance. Furthermore, gasoline is a mixture of hydrocarbons with 4 to 12 carbon atoms, while methanol is an active substance with a single carbon atom and a hydroxyl group, so there is a certain gap in compatibility with gasoline. Also, the boiling po...
