Abstract

The invention relates to methanol diesel oil which comprises methanol, diesel oil, fatty acid, petroleum acid, cosolvent, aviation kerosene, a cetane number improver and zinc peroxide. The invention further relates to a preparation method of the methanol diesel oil. According to the methanol diesel oil, the content of methanol in a system is greater, the methanol diesel oil has better mutual solubility with fossil diesel oil, the performance of the methanol diesel oil is improved obviously, and the methanol diesel oil can serve as -20# diesel oil for use, and is safe, environment-friendly and low in raw materials cost. The preparation method is simple in step, mild in condition and suitable for large-scale industrial production.

Description

technical field [0001] The invention relates to the field of petrochemical industry, in particular to methanol diesel and a preparation method thereof. Background technique [0002] Methanol diesel is a fuel that is blended with diesel, methanol and optional additives according to a certain volume or mass ratio through a strict process. The use of methanol diesel can not only save oil resources, reduce costs, but also reduce air pollution. It is an environmentally friendly and clean new energy source that has received extensive attention. [0003] Although methanol diesel has very obvious advantages over traditional petrochemical resources, it also has various defects, such as high corrosion, poor solubility, low flash point, poor power, etc., one of the important ones is methanol and diesel. Poor miscibility. Methanol is a polar molecule, and the alkanes in diesel oil are non-polar molecules. According to the principle of similar miscibility, it is difficult for methanol ...
