Abstract
The invention discloses a method for decoloring and deodorizing diesel fuel oil and increasing yield, comprising the following steps of: A, adding raw oil to a mixture comprising activated clay and other solid absorbents, absorbing and filtering the raw oil to obtain a good-color oil product and a semi-finished oil product; and B, adding a catalyst into the obtained semi-finished oil product obtained in the step A, and making the semi-finished oil product react for 3-5 hours at normal temperature to obtain a good-color oil product. The invention can greatly deodorizes and decolors, and therefore, the oil product has no objectional odor, changes into a primrose color and achieves a 3.5 level of a Chinese standard GB 252-2000. Because the method of the invention is used for treating an oil product with a color which does not conform to a standard into an oil product with a color which conforms to the standard, the yield of the oil product is increased finally.
Description
Technical field
The present invention relates to the deep process technology field of oil product, specifically, the present invention is a kind of decoloring and deodorizing diesel fuel oil and the method that improves yield.
Background technology
At present, by raw material through refinery and catalytic diesel oil and Pyrolysis gas oil PGO because its colloid is big, wax is big, has unsaturated olefin, therefore meets airborne oxygen contact oxidation, color blackening take place.Conventional method is to use strong acid, and the vitriol oil as 98% is handled, and adds the alkali neutralization, so not only the composition of oil is caused to a certain degree destruction and slag yield height.Though the different slag yield that causes of oil product is also different, slag yield generally can be in 6～10% higher level.In addition, add in the alkali cleaning and the time emulsification also easily takes place, separation difficulty, production efficiency is low.
Summary of the invention
The purpose of this invention is to provide a kind of decoloring and deodorizing diesel fuel oil and improve the method for yield.
The present invention is in order to realize above-mentioned goal of the invention, particularly, the present invention by the following technical solutions:
A kind of decoloring and deodorizing diesel fuel oil also improves the method for yield, adopts following steps:
A. stock oil is joined in the mixture of forming by atlapulgite and other solid adsorbent, filter and absorb, obtain coloury oil product and half-finished oil product; The part by weight of atlapulgite and other solid adsorbent is 1: 0.3～0.6; Other solid adsorbent are the mixture of aluminum oxide, magnesium oxide and silicon-dioxide, and the part by weight of aluminum oxide, magnesium oxide and silicon-dioxide is 1: 0.9～1.6: 0.8～1.2;
B. add catalyzer in half-finished oil product of gained in steps A, the part by weight of half-finished oil product and catalyzer is 1: 0.01～0.05, after normal-temperature reaction 0.5-1 hour, obtains coloury oil product.
In steps A, be outside the improvement of the present invention: when filtering and absorb, in the atlapulgite that ordinary method is used, added other solid adsorbent components.Solid adsorbent is made up of aluminum oxide, magnesium oxide and silicon-dioxide, and its preferred part by weight is 1: 1: 1.
Part by weight between stock oil and the adsorbent mixtures (atlapulgite and other solid adsorbent) is not a key of the present invention, and this ratio is 0.1～0.2: 1 usually.
Step B purifies the absorption tower at bubbling to carry out.Catalyzer is made up of the raw material of following weight ratio: furfural 60%, Virahol 10%, hexahydroaniline 5%, thanomin 5%, hexanediamine 10%, hypochlorite 10%.
The invention has the advantages that: the present invention can remove peculiar smell and slough pigment greatly, makes the oil product free from extraneous odour, and color becomes faint yellow, among the GB252-2000 that is up to state standards 3.5 grades.Because the present invention is with the non-compliant oil product of color and luster after treatment, makes it conformance with standard, thereby has also finally improved the yield of oil product.
