a diesel fuel additive

Abstract

The invention relates to a diesel fuel additive for improving diesel fuel performances. The diesel fuel additive is a dual-purpose additive mixture which can be utilized as a diesel fuel anti-wear agent and a diesel fuel emulsion inhibitor. The diesel fuel additive for improving diesel oil performances comprises components of A) tall oil fatty acid, B) oleamide, and C) naphthenic acid imidazoline, wherein a weight ratio of the component A to the component B to the component C is 100: (5 to 100): (5 to 50) and the component A, the component B and the component C can be respectively added directly into diesel fuel for use. The component A, the component B and the component C also can be mixed into a lubricant additive and then the lubricant additive is added into diesel fuel, wherein an additive amount is in a range of 50 to 300 mg / kg. The diesel fuel additive for improving diesel fuel performances has prominent substantive characteristics and remarkable improvements that 1, the diesel fuel additive can improve lubricity of diesel fuel and thus can be utilized as a diesel fuel anti-wear agent; and 2, the diesel fuel additive has obvious anti-emulsification effects on diesel fuel, can inhibit emulsification of diesel fuel and can be utilized as a diesel fuel emulsion inhibitor for use.

Description

technical field [0001] The invention relates to a diesel performance-improving additive, which is a double-effect additive mixture which can be used as a diesel antiwear agent and a diesel emulsification inhibitor. technical background [0002] At present, the low sulfur content of vehicle diesel oil is the result of the improvement of social environmental protection awareness. Low sulfur content of vehicle diesel oil means that the quality of diesel oil is improved, the content of aromatic hydrocarbons and polar substances is reduced, and it is more environmentally friendly when used. Due to the harsh hydrogenation process commonly used in low-sulfur diesel oil, the oxygen-containing and nitrogen-containing compounds are reduced, and the natural lubricating performance of diesel oil is reduced, which causes wear and tear of automobile fuel injection pumps that rely on diesel oil for lubrication, and reduces their service life. Adding additives to diesel oil to improve the l...

Problems solved by technology

Diesel oil that has become turbid often cannot leave the factory due to its poor appearance. Although this turbid diesel oil can be restored to a clear state after being stored for a certain period of time in the irrigation area, the long-term occupation of the diesel tank affects production efficiency.

In addition, due to emulsification, when the bottom water of the diesel tank is drained, a large amount of emulsified turbid liquid is often discharged from the water, and the emulsified turbid liquid has a high oil content, which has an adverse effect on the treatment of sewage
