Embodiment 1

[0024] 1. Preparation of oil dechlorination agent

[0025] Take 50g of metal sodium, 5g of sodium oxide, 10g of metal potassium and 1g of potassium oxide and mix to obtain an oil product dechlorination agent composition.

[0026] 2. Dechlorination reaction, which specifically includes the following steps: (1) Replace the 100mL reactor by high-temperature drying, vacuum replacement, etc., to ensure that the reaction system is anhydrous and oxygen-free; (2) add 10g of the above-mentioned Oil product dechlorination agent; (3) add the naphtha of 10g certain refinery (chlorine content 30ppm, PONA group forms n-paraffin content 34.71%, isoparaffin content 14.95%, olefin content 30.01%, naphthene content 14.96% , aromatics content 5.12%); (4) stirring at 30° C. for 10 min; (5) stop the reaction, take out a small amount of oil for chlorine content analysis: the chlorine content is 2.7 ppm. The results are shown in Table 1.

Embodiment 2

[0028] Same as Example 1, except that the reaction temperature is 60°C. See Table 1 for the data.

Embodiment 3

[0030] Same as Example 1, except that the reaction temperature is 95°C. See Table 1 for the data.

Abstract

The invention discloses an efficient oil dechlorinating agent which mainly contains alkali metal simple substances, alkali oxides or mixtures of the alkali metal simple substances and the alkali oxides. The alkali metal simple substances are selected from one or more of lithium, sodium, potassium, rubidium and cesium. The invention also discloses an oil dechlorinating method adopting the oil dechlorinating agent. According to the oil dechlorinating method, the mass content of chlorine in oil can be quickly reduced to about 1 ppm; the dechlorinating agent consumption is small and can be reused; and chlorine residues in the oil can be effectively reduced even a little of the dechlorinating agent is used. The oil dechlorinating agent is simple to prepare, operation conditions of the dechlorinating reaction are convenient, the application range of the oil is wide, and the oil can completely meet requirements of downstream sections as well as civil and military use.

Description

technical field [0001] The invention belongs to the field of petrochemical oil dechlorination, and in particular relates to a high-efficiency dechlorination agent for oil and a method for dechlorinating oil by using the dechlorination agent. Background technique [0002] Chlorine is a common catalyst poison, with high electron affinity and mobility, it is easy to react with metal ions, and often migrates downstream with the process fluid, causing permanent catalyst poisoning, and it is often the whole bed. In recent years, in order to increase the output of crude oil, various oil recovery additives have been widely used in various oil fields, such as demulsifiers, wax removers, acidifiers, etc., many of which contain various types of organic chlorides. These organic chlorides It is insoluble in water, has good thermal stability, and is difficult to remove by electric desalination. Most of it exists in the straight-run naphtha fraction of atmospheric and vacuum products. Dur...
