Embodiment 1

[0019] A catalytic gasoline sweetening activator, composed of the following components by weight percentage: absolute ethanol 49%, octadecyl benzyl ammonium chloride 6%, caustic soda 6%, isopropanol 5%, triethanolamine Modified sodium lignosulfonate 1%, KH550 modified nanometer mesoporous alumina 0.1%, the balance of water.

[0020] The preparation method of described triethanolamine modified sodium lignosulfonate is as follows:

[0021] (1) Slowly add an appropriate amount of triethanolamine into an appropriate amount of epichlorohydrin, and stir and react at 70°C for 4 hours to obtain an intermediate;

[0022] (2) Fully dissolve an appropriate amount of sodium lignosulfonate in water to obtain an aqueous solution of sodium lignosulfonate, and then slowly add the intermediate into the aqueous solution of sodium lignosulfonate at a pH of 10 and a temperature of 60°C The mixture was stirred and reacted for 2 hours to obtain triethanolamine-modified sodium lignosulfonate.

Abstract

The invention discloses a catalytic gasoline de-mercaptan activating agent and a preparation method thereof. The catalytic gasoline de-mercaptan activating agent is prepared from the following ingredients in percentage by weight: 49 to 63 percent of absolute ethyl alcohol, 6 to 8 percent of octadecyl benzyl ammonium chloride, 6 to 7 percent of caustic soda flakes, 5 to 7 percent of isopropanol, 1to 3 percent of triethanolamine modified sodium lignin sulfonate, 0.1 to 0.2 percent of KH550 modified nanometer mesoporous alumina and the balance of water. The catalytic gasoline de-mercaptan activating agent obtained by the invention has good catalyst activation effects; the water-soluble and oil-soluble impurities on a catalyst fixing bed can be effectively removed, so that the use period of the catalysis fixing bed can be better prolonged; the deodorization rate of the gasoline and the test qualification rate of the refined gasoline are improved.

Description

technical field [0001] The invention relates to the field of petroleum processing, in particular to a catalytic gasoline sweetening activator and a manufacturing method thereof. Background technique [0002] The light fuel oil obtained after primary and secondary processing of petroleum contains a certain amount of sulfides, mainly including mercaptans, sulfides, disulfides, and thiophenes. Among them, reactive sulfide mercaptan (RSH) has a greater impact on oil quality. Its existence not only makes the oil produce a foul smell, but also because mercaptan is a free radical initiator, which can promote the oxidation of unstable components in the oil and superimpose to form colloids, thereby reducing the stability of the oil; sulfur Alcohols are also weakly acidic and corrosive, and mercaptans also affect the susceptibility of oil to additives, such as antiknock agents, antioxidants, metal deactivators, etc. Therefore, in the process of petroleum processing, it is necessary ...
