Biological diesel-oil stabilized additive, its production and use

Abstract

A safe biological diesel-oil consists of main antioxidant, synergist, deoxidant and solvent oil. The main antioxidant is 2-tert-4-methoxyphenol or3-tert-4-methoxyphenol or 2, 6-di-tert mixed phenol or 2-tert-hydroquinone or hemimelitic phenol or two or above substances mixture; synergist is mixture of ethylenediamine tetraacetic acid salt or citric acid, citrate ester or propanediol or poly-phosphoric acid or two or above substances mixture; deoxidant is vitamin E or carotenoid or ascorbic acid or ester ascorbate mixture or two or above substances mixture, main antioxidant is 4-6wt%, synergist is 2-36wt%, deoxidant is 4-6wt% and solvent oil is residue. It has better stability.

Description

Technical field: [0001] The invention relates to an additive for regenerated fuel oil and a preparation method thereof. Background technique: [0002] Although petroleum is still one of the main energy sources in this century, it is difficult to regenerate and faces the danger of depletion. Moreover, it is not a clean energy source. Therefore, the substitutability, renewability and green environmental protection of fuel oil have attracted various countries. The importance of fuel oil has become a technical hotspot of fuel oil. Biodiesel, which uses animal and vegetable oils as raw materials and can be used as fuel after modification, is a fuel oil that meets the above characteristics. It is developing rapidly as a renewable clean energy that can replace petroleum fuels. Abroad, especially Developed countries such as the European Union, the United States, and Japan have been widely used, and domestic governments at all levels and business circles have also attracted attention...

Problems solved by technology

As we all know, biodiesel is a mixture of fatty acid methyl esters with different saturations and carbon chain lengths. During production or use, it has poor stability and is easily oxidized. The color will continue to darken, and colloids and insolubles will also increase. , this phenomenon becomes more and more obvious with the prolongation of storage time, which directly affects the performance of biodiesel, resulting in blockage of engine filter, fuel system cannot supply fuel normally, affects fuel injection atomization, leads to incomplete combustion, and even Excessive carbon deposits are formed in the engine, clogging the fuel injectors
