Embodiment 1

[0011] Take 30 parts of tetraethylammonium chloride, 20 parts of glycerol, 20 parts of ethylene glycol, 15 parts of potassium hydroxide, 10 parts of sulfonated lignin, and 10 parts of water in parts by weight. Pour into the reaction kettle, heat the reaction kettle to 50~60℃ with a water bath, keep stirring for 2~6 hours and then lower to room temperature, then heat the reaction kettle to 60℃ again by heating with a water bath, and keep stirring for 12~24 Hours.

Embodiment 2

[0013] Take 60 parts of tetraethylammonium chloride, 40 parts of glycerol, 30 parts of ethylene glycol, 30 parts of potassium hydroxide, 15 parts of sulfonated lignin, and 30 parts of water in parts by weight. Pour into the reaction kettle, heat the reaction kettle to 50~60℃ with a water bath, keep stirring for 2~6 hours and then lower to room temperature, then heat the reaction kettle to 60℃ again by heating with a water bath, and keep stirring for 12~24 Hours.

Embodiment 3

[0015] Take 40 parts of tetraethylammonium chloride, 30 parts of glycerol, 25 parts of ethylene glycol, 20 parts of potassium hydroxide, 13 parts of sulfonated lignin and 20 parts of water in parts by weight. Pour into the reaction kettle, heat the reaction kettle to 50~60℃ with a water bath, keep stirring for 2~6 hours and then lower to room temperature, then heat the reaction kettle to 60℃ again by heating with a water bath, and keep stirring for 12~24 Hours.

Abstract

The invention discloses a high-cleanness agent for removing mercaptan in gasoline. The high-cleanness agent is prepared from the following components in parts by weight: 30 to 60 parts of tetraethylammonium chloride, 20 to 40 parts of glycerol, 20 to 30 parts of ethylene glycol, 15 to 30 parts of potassium hydroxide, 10 to 15 parts of lignosulfonate and 10 to 30 parts of water. Meanwhile, the invention also discloses a method for the high-cleanness agent for removing the mercaptan in the gasoline. Compared with a traditional technology, the high-cleanness agent disclosed by the invention has the advantages of low production cost, low consumption, high intersolubility with the gasoline and high mercaptan removing efficiency; meanwhile, the content of chloride ions is low, so that secondary pollution to the environment is avoided.

Description

Technical field [0001] The invention belongs to the field of chemical industry, and specifically relates to a high-clean gasoline demercaptan agent and a preparation method thereof. Background technique [0002] FCC gasoline contains more mercaptans, which not only produces a disgusting odor, but also deteriorates the stability of the oil. Because mercaptan is an oxidation initiator, it can make the unstable compounds in the oil superimpose to form a colloidal substance. Mercaptans are also corrosive and can enhance the corrosiveness of elemental sulfur. Therefore, it is very important to use a suitable sweetening agent in the sweetening process. Summary of the invention [0003] Objective of the invention: The objective of the present invention is to provide a high-clean gasoline desulfurizing agent for the shortcomings of the prior art. [0004] Another object of the present invention is to provide a method for preparing the above-mentioned high-clean gasoline sweetening agent....
