Problems solved by technology

While traditional HDS technology removes a large amount of sulfide in gasoline, it also hydrogenates the high-octane component in gasoline-olefins, resulting in loss of octane number and poor regeneration performance. Therefore, the development has a high desulfurization activity. , less impact on gasoline octane number and good regeneration performance, hydrodesulfurization technology has become a hot spot in current hydrodesulfurization technology research
In addition, most of the existing desulfurizers use activated carbon, ZSM-5 and other materials, and illite is rarely used due to its own structure

Embodiment 1

[0017] In the embodiment of the present invention, a gasoline desulfurizer is composed of the following raw materials in parts by weight: 21 parts of illite, 1 part of perillyl alcohol, 3 parts of salicylic acid, and 5 parts of triethylenediamine.

[0018] Triethylenediamine is mixed with 8.2 times the mass of ethanol with a volume concentration of 50% to prepare a triethylenediamine solution; perillyl alcohol is mixed with 1.1 times the mass of ethanol to prepare a perillyl alcohol solution. The illite was crushed and passed through a 120-mesh sieve, and then the triethylenediamine solution was added. The temperature was raised to 73°C and sealed and stirred for 2.2h at this temperature. Then the temperature was raised to 88°C and salicylic acid was added dropwise. Ultrasonic treatment at temperature for 37 minutes, ultrasonic power of 900W, add perillyl alcohol solution and stir to dryness at a temperature of 99°C, and then calcinate in a muffle furnace at 440°C for 3.8 hours to...

[0020] In the embodiment of the present invention, a gasoline desulfurizer is composed of the following raw materials in parts by weight: 29 parts of illite, 5 parts of perillyl alcohol, 7 parts of salicylic acid, and 12 parts of triethylenediamine.

[0021] Triethylenediamine is mixed with 8.2 times the mass of 50% ethanol to prepare a triethylenediamine solution; perillyl alcohol is mixed with 1.1 times the mass of ethanol to prepare a perillyl alcohol solution. The illite was crushed and passed through a 120-mesh sieve, and then the triethylenediamine solution was added. The temperature was raised to 73°C and sealed and stirred for 2.2h at this temperature. Then the temperature was raised to 88°C and salicylic acid was added dropwise. Ultrasonic treatment at temperature for 37 minutes, ultrasonic power of 900W, add perillyl alcohol solution and stir to dryness at a temperature of 101°C, and then calcinate in a muffle furnace at 440°C for 3.8 hours to obtain a desulfurizer.

Abstract

The invention discloses a gasoline desulfurization agent and a preparation method and application thereof. The gasoline desulfurization agent is composed of the following raw materials of, by weight, 21-29 parts of illite, 1-5 parts of perilla alcohol, 3-7 parts of salicylic acid and 5-12 parts of triethylene diamine. The illite is smashed and added to the triethylene diamine solution to be subjected to sealing, heating and stirring treatment, then the salicylic acid is dropwise added, ultrasonic treatment is conducted, then the perilla alcohol solution is added and stirred till being dry, and the desulfurization agent is obtained after calcination. Under the situation that the RON loss of gasoline is smaller than 2.0, the ultra-low sulfur content gasoline with the sulfur content being below 6 microgram / g can be obtained. The sulfur selectivity is good, the desulfurization depth is high, the octane number loss caused by olefin hydrogenation saturation is avoided while sulfur-containing compounds in the gasoline are deeply removed, the service life is long, and the gasoline desulfurization agent is environmentally friendly, free of secondary pollution and good in regeneration performance. The preparation process is simple, the raw materials are easy to obtain, the production cost is low, and the gasoline desulfurization agent is suitable for industrial production.

Description

Technical field [0001] The invention relates to the technical field of gasoline, in particular to a gasoline desulfurizer and a preparation method and application thereof. Background technique [0002] The sulfur-containing compounds in gasoline will generate sulfur oxides SOx after combustion, which can poison the automobile exhaust gas conversion system catalysts, further affecting the effective conversion of NOx, CO, and CH, and sulfur oxides discharged into the atmosphere will form acid rain pollution. As people pay more and more attention to environmental protection, environmental protection laws and regulations are becoming stricter, and the global gasoline sulfur content index is becoming stricter. Similarly, my country's automotive gasoline standards have higher and higher requirements for sulfur content, which puts forward higher requirements for gasoline desulfurization technology in my country's oil refineries. [0003] The adsorption desulfurization method is one of ma...
