Micro-emulsified diesel oil and preparation method thereof

Abstract

The invention discloses micro-emulsified diesel oil which consists of the following components in percentage by weight: 65-75% of diesel oil, 12-20% of water, 5-15% of emulsifying agent and 3-6% of cetane number improving agent, wherein the emulsifying agent is composed of 27-32% of naphthenic acid, 28-32% of animal and plant oleic acid, 6-10% of peregal, 2-4% of sodium hydroxide, 3-5% of polyethylene polyamine, 5-7% of cyclohexane, 8-12% of isoamylol, 4-6% of sec-octanol and 4-6% of potassium hydroxide. The preparation method comprises the following steps of: respectively preparing the cetane number improving agent and the emulsifying agent; and mixing proper amounts of prepared cetane number improving agent, emulsifying agent and diesel oil with water, stirring for 40 minutes and standing by for 4hours. The micro-emulsified diesel oil is transparent in appearance and is free from mechanical impurity, and micro-emulsified diesel oil can reach international diesel oil standard and is suitable for various diesel oil machineries; and the micro-emulsified diesel oil is free from layering even after 1 year of quality guarantee period, and has an excellent intersolubility.

Description

technical field [0001] The invention relates to a carbon-containing liquid fuel, in particular to a micro-emulsion diesel oil and a preparation method thereof. Background technique [0002] It is a well-known fact that the world's energy shortage will further intensify. This is the inevitable result of the gradual reduction of oil reserves. With the depletion of oil resources, the price of refined oil continues to skyrocket. my country is a big agricultural country, and a large number of agricultural machinery, transportation vehicles, ships, industrial refineries, and boilers in hotels and schools mostly use diesel as the main fuel, and the sharp rise in diesel prices has increased the cost of various industries and affected social and economic development. develop. [0003] For this reason, many scientists are researching and exploring various new energy sources that can save energy or replace petroleum products, such as wind energy, solar energy, biomass, hydrogen ene...

AI Technical Summary

Problems solved by technology

[0004] But, although the kind of existing micro-emulsion diesel oil is a lot, generally there is following problem: the shelf-life of micro-emulsion diesel oil all will take place stratification phenomenon i.e. water is separated from oil, and there is milk-like water in the bottom layer Emulsion, and the freezing point of the existing micro-emulsion diesel oil is usually above 10°C, it cannot be used normally in winter, and the seasonality is very strong

In addition, in terms of power, it can't play a good role in increasing the power. It can only approach the power of diesel, and can't better adjust the state according to the needs of machinery.
