Methanol-diesel and preparation thereof

Abstract

The invention relates to liquid fuel oil, in particular to methanol diesel oil and a method for preparing the same. The methanol diesel oil comprises the following components in weight percentage: 40 to 80 percent of diesel oil, 5 to 20 percent of methanol and 1 to 10 percent of additive. The formula with unique auxiliary materials and the additive is introduced to the fuel, thereby effectively solving the problem that the methanol and the diesel oil are hard to mutually dissolve and completely replacing the commercial diesel oil to be used in various environments; moreover, the methanol diesel oil also has the advantages of low cost and good burning property, starting property and power performance; in particular, carbon monoxide and the smoke intensity in the tail gas emission are obviously reduced, so that the methanol diesel oil is a perfect fuel.

Description

technical field [0001] The invention relates to the category of liquid fuel oil, which belongs to the category of energy, and specifically relates to a methanol diesel and a production method thereof. Background technique [0002] As an energy source, diesel oil is widely used in various fields. With the increase of crude oil energy consumption, the price of diesel oil is also rising step by step. It is a common problem that people face to find alternative energy sources, reduce the price of diesel oil, and then reduce the cost. As an alternative fuel, the development prospect of methanol in our country is gradually becoming clear. At present, there are roughly two methods for mixing diesel oil with methanol: miscible method and emulsification method. The emulsification method is to study the formulation, emulsification technology and application performance of emulsified diesel oil. The miscibility method is to study the formation of a stable, uniform and transparent mixt...

AI Technical Summary

Problems solved by technology

[0006] 1. The selected additives are complex in composition, expensive, large in dosage, poor in stability and cannot adapt to various climate environments and storage conditions;

[0007] 2. It cannot fundamentally solve methanol's long flame retardation period, prone to cylinder knocking, poor lubricity and corrosion to machine parts;

[0008] 3. The source of additives is limited, which does not meet the needs of large-scale industrialization. The introduction of some additives brings new sources of exhaust pollution;

[0009] 4. The raw material cost of the produced methanol diesel is much higher than that of the international common diesel at that time, and it is impossible to play the role of diesel engine substitute fuel;

[0010] 5. Most of the prepared methanol diesel is limited to the laboratory test stage, and has not been tested on roads with many models, multiple road conditions, long periods of time, and various climates, or the vehicle power and handling have dropped significantly
