Problems solved by technology

However, because the miscibility of biodiesel and low-sulfur diesel is not good enough, if 50% of the amount of low-sulfur diesel is added to low-sulfur diesel, it needs constant vigorous mechanical stirring to make the two completely miscible. Therefore, If you want to directly use biodiesel to improve the lubricity of low-sulfur diesel, on the one hand, it is inconvenient to use; Sulfur Diesel Combustion Rate

Abstract

The invention relates to a low-sulfur diesel additive and a preparation technology thereof. The low-sulfur diesel additive comprises the following components in parts by weight: 40-45 parts of biodiesel, 3-8 parts of glyceryl stearate, 2-5 parts of ethyl stearate, 9-15 parts of oleamide, 20-24 parts of solubilizer, 6-10 parts of detergent and 5-8 parts of antioxidant. A preparation method of the low-sulfur diesel additive comprises the following steps: adding the biodiesel and solubilizer into a reaction container; heating and stirring and adding the glyceryl stearate, ethyl stearate and oleamide; adding the detergent and the antioxidant and stirring and mixing; and after that, filtering to obtain the low-sulfur diesel additive. The advantages of the invention are as follows: the low-sulfur diesel additive can be dissolved well with diesel, and the lubricating property of the diesel can be obviously improved; and the low-sulfur diesel additive also has oxidation resistance as well as detergency and dispersibility.

Description

technical field [0001] The invention relates to the field of additives, in particular to a low-sulfur diesel additive and a manufacturing process thereof. Background technique [0002] Diesel is a product of petroleum refining, which occupies a relatively high share in the fuel structure of all countries in the world and has become an important power fuel. With the acceleration of dieselization of vehicles worldwide, the demand for diesel will increase in the future, but the exhaust gas emitted after diesel combustion is also increasingly harmful to the environment. For example, sulfur dioxide and nitrogen oxides in the exhaust gas not only form acid rain in cities and surrounding areas, but also seriously damage the earth's ozone layer. Particulate matter (PM) contains a variety of substances that are listed as possible carcinogens by international research institutions. At the same time, particulate matter is the cause of fog. The culprit of smog. Studies have shown that...
