Abstract
The present invention discloses a multipurpose diesel oil additive with the components (by weight portions) of: amyl or isoamyl nitrate in 3-10, 2,6-ditert-butyl p-cresol in 3-6, polymethyl acrylate in 1-4 and poly-alpha olefine in 4-8.
Description
The present invention relates to a kind of diesel-dope and preparation method thereof, more particularly, the present invention relates to a kind of multi-effect diesel compound additives and preparation method thereof.
Generally speaking, the diesel oil distillate that is obtained by oil refining apparatus such as the atmospheric and vacuum distillation of refinery, thermally splitting, catalytic cracking, coking all will add dissimilar additives as required, just can reach the standard of diesel product of the different trades mark of market demands through suitable allotment.
Allotment during diesel product used additive have a variety of, for example cetane value conditioning agent, antioxidizing and antigum agent, pour point depressant etc.Generally they are to join respectively in the mixture of allotment, so many, the complex process of Tiao Pei step.
The purpose of this invention is to provide a kind of multi-effect diesel compound additives, it is added separately in the diesel oil of low-quality, just can obtain No. 0 and-No. 10 diesel oil through suitable allotment.The step that so just can simplify the operation is saved facility investment, and can make full use of low-quality diesel oil and be mixed with the fine-quality diesel oil product.
Multi-effect diesel compound additives of the present invention has the effect that improves diesel cetane-number, anti-oxidantly prevents the sedimentary effect of rubber, and reduces the zero pour of diesel oil, improves the storage stability and the use properties of diesel oil.
Preparing the used cetane value conditioning agent of multi-effect diesel compound additives of the present invention is methyl nitrate, amyl nitrate or isoamyl nitrate or its mixture.
Prepare the used antioxidizing and antigum agent of multi-effect diesel compound additives of the present invention and select 2,6 ditertiary butyl p cresol for use.
Preparing the used pour point depressant of multi-effect diesel compound additives of the present invention, can to select molecular-weight average for use be polymethacrylate, alkylnaphthalene and the poly-alpha olefins of 10000-20000.
Preparing the used various raw materials of multi-effect diesel compound additives of the present invention all is the commercially available prod, can buy from industrial chemicals market.
The compound method of multi-effect diesel compound additives of the present invention is very simple, at normal temperatures and pressures, the feed composition of selecting for use is joined in the auger tank in proportion, stirs and just can obtain needed diesel fuel complex additive in 10-30 minute.This additive is greenish orange look liquid.
Feed composition that multi-effect diesel compound additives of the present invention contained and content thereof (weight part) are as follows:
Amyl nitrate or isoamyl nitrate 3-10
2,6 ditertiary butyl p cresol 3-6
Polymethacrylate 1-4
Poly-alpha olefins 4-8
Can utilize the method (promptly utilizing Venturi tube to drip the blended method) of dripping mixed flow directly multi-effect diesel compound additives of the present invention to be joined in the gas oil fraction, multiple low-quality diesel oil distillate is deployed into the diesel product of the different trades mark that meet national standard, improves the utility value of inferior quality diesel oil.Said inferior quality diesel oil comprises gas oil fraction and the inferior quality diesel product that oil refining apparatus such as crude oil atmospheric vacuum distillation, thermally splitting, catalytic cracking, coking obtain.
-No. 20 of 30-70 weight part--in the mixture of the low-quality gas oil of No. 50 fine-quality diesel oils and 70-30 weight part, the multi-effect diesel compound additives of the present invention that adds the 0.5-1.5 weight part with the method for dripping mixed flow just can be mixed with No. 0 or-No. 10 diesel oil.
The present invention is described in detail for following embodiment.
