Abstract
The invention discloses a method for improving oxidation stability of shale diesel oil. The method comprises the following steps: mixing the shale diesel oil with a catalyst; introducing oxygen at a certain temperature, and reacting for a certain period of time to obtain oxidized shale diesel oil; and distilling the oxidized shale diesel oil, wherein the smell and the color of the refined shale diesel oil are obviously improved; and the oxidation stability can reach the standard diesel index requirements. The method is simple in process, easy to operate, mild in reaction condition, low in investment cost, and significant in economic benefits. By virtue of the technique, the stability of the shale diesel oil can be significantly improved; and the quantity and the quality of the shale diesel oil are greatly improved.
Description
Technical field
The invention belongs to oil product processing technique field, be specifically related to a kind of working method improving shale diesel oil oxidation stability.
Background technology
Shale oil is the method by low-temperature pyrolysis, makes the organic decomposes in oil shale, and the mixture of the various organic compound obtained.Although all contain a large amount of hydrocarbon polymers compared with natural crude oil, natural crude oil is mainly made up of stable hydrocarbon, and shale oil contains organic heterocyclic molecule and the unsaturated hydrocarbons compounds such as more nitrogen, sulphur, oxygen than natural crude oil.Shale diesel oil is the distillate of shale oil true boiling point cutting, and in shale diesel oil fraction, colloid and carbon residue exceed the specification of quality that target specifies, and the existence of colloid has bad impact to the stable of oil product and engine.At present, about improving the report of shale diesel oil oxidation stability deep processing research and seldom and not yet ripe, the stability in storage of shale diesel oil is poor, easily forms insolubles after storage, has had a strong impact on engine fuel to the normal work being and overall performance.So the stability how improving shale diesel oil is the important topic that people are all the time be concerned about.
Summary of the invention
The object of this invention is to provide a kind of technique simple, easy handling, reaction conditions is gentle, and input cost is low, improves the working method of shale diesel oil oxidation stability.
For achieving the above object, the technical solution used in the present invention is: by shale diesel oil and catalyst mix, pass into oxygen at a certain temperature, reaction certain hour, obtain oxidized shale diesel oil, distilled by oxidized shale diesel oil, gained refines shale diesel oil smell and color is obviously improved, and oxidation stability can reach standard diesel oil index request.
Present invention process is simple, easy handling, and reaction conditions is gentle, and input cost is low, remarkable in economical benefits.Adopt above-mentioned processing method can significantly improve the stability of shale diesel oil, greatly improve quality and the quality of shale diesel oil.
