High-efficiency oil-saving agent, preparation method and application thereof

Abstract

The invention discloses a high-efficiency oil-saving agent, a preparation method and the application thereof. The high-efficiency oil-saving agent comprises 0.05-2.0% of fluorenone compound, 0.05-2.0% of nitrotoluene, 80-99.5% of camphor, 0.3-12% of borneol and balance low-grade fatty alcohol. The preparation method of the high-efficiency oil-saving agent comprises the steps of: completely dissolving the fluorenone compound and the nitrotoluene into the low-grade fatty alcohol, then fully mixing the camphor and the borneol, and obtaining the high-efficiency oil-saving agent. When being added into fuel oil, the high-efficiency oil-saving agent has the oil-saving rate reaching up to 30%. As metal salt is not used as an active agent in the high-efficiency oil-saving agent, residues are not left after the fuel oil is fully burnt, and the service life of an engine can be prolonged; the high-efficiency oil-saving agent is solid additive, thus being convenient for transportation and storage, easily dissolved into the fuel oil and low in adding proportion, and not changing the physical property of the fuel oil; and furthermore, the high-efficiency oil-saving agent is safe and can improve the antiknock property. The invention has simple preparation method and low cost, and is wide in application prospect.

Description

technical field [0001] The invention belongs to the field of petrochemical industry, in particular to a high-efficiency fuel-saving agent and its preparation method and application. Background technique [0002] With the rapid development of the transportation industry in today's world, the demand for transportation oil is getting higher and higher. However, the non-renewability of oil resources and the current depletion of oil reserves, as well as the sharp increase in car ownership and production, have made the oil consumption of transportation vehicles increasingly tense. How to effectively improve the combustion efficiency of gasoline, diesel oil, etc. in internal combustion engines and save fuel has become one of the hot technologies that countries all over the world are competing to study. Adding fuel-saving agents to fuel oil is simple and effective, and has attracted the attention of the world. There have been related research work on fuel-saving agents at home and ...

Problems solved by technology

Adding fuel-saving agents to fuel oil is simple and effective, and has attracted the attention of the world. There have been related research work on fuel-saving agents at home and abroad, mainly including the following: (1) Adding metal salts to fuel oil as active ingredients, It is an important class of fuel-saving agents at present, such as U.S. Patent US4195190, which uses ferrous sulfate and picric acid as active ingredients, dissolves in lower alcohols and toluene to form a liquid fuel-saving agent; the application number is 97103812.0, and the invention name is "gasoline The national invention patent application for "combustion enhancer" discloses a fuel-saving agent with ferrocene as the active ingredient; however, metal salts will form residues after burning, which will cause increased mechanical friction and damage the engine, and this type of fuel-saving agent It is generally liquid, and the product is not suitable for transportation and carrying; (2) Using natural plant extracts as active ingredients to save fuel, the national invention patent application with the application number 93101691.6 and the invention name "Synthesis of New Gasoline and Diesel Combustion Accelerator" has been published A fuel-saving agent with Korean ginseng or ginseng rhizome extract as active ingredient, the fuel-saving rate is about 10%, but this method has poor popularity, high addition amount, and complicated preparation process; (3) by adding alkanes or alcohols organic matter such as cyanide, change the octane number of the fuel, improve the anti-knock and combustion performance of the fuel, but the fuel saving rate is generally not high, around 10%.
