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

[0018] 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.

[0019] The triethylenediamine is mixed with 8.2 times its mass of ethanol with a volume concentration of 50% to prepare a triethylenediamine solution; the perillyl alcohol is mixed with its 1.1 times its mass of ethanol to prepare a perillyl alcohol solution. Crush illite and pass through a 120 mesh sieve, then add triethylenediamine solution, raise the temperature to 73°C and seal and stir at this temperature for 2.2h, then raise the temperature to 88°C and add salicylic acid dropwise, after the dropwise addition is completed, in the Ultrasonic treatment at high temperature for 37 minutes, ultrasonic power 900W, then add perillyl alcohol solution and stir at 99°C until dry, then calcined in a muffle furnace at 440°C for 3.8h to obt...

Embodiment 2

[0021] 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.

[0022] Triethylenediamine is mixed with 50% ethanol whose mass is 8.2 times to prepare triethylenediamine solution; perillyl alcohol is mixed with ethanol whose mass is 1.1 times to prepare perillyl alcohol solution. Crush illite and pass through a 120 mesh sieve, then add triethylenediamine solution, raise the temperature to 73°C and seal and stir at this temperature for 2.2h, then raise the temperature to 88°C and add salicylic acid dropwise, after the dropwise addition is completed, in the Ultrasonic treatment at high temperature for 37 minutes, ultrasonic power of 900W, then add perilla alcohol solution and stir at 101°C until dry, then calcined in a muffle furnace at 440°C for 3.8h to obtain the desulfurizer.

Embodiment 3

[0024] In the embodiment of the present invention, a gasoline desulfurizer is composed of the following raw materials in parts by weight: 23 parts of illite, 2 parts of perillyl alcohol, 4 parts of salicylic acid, and 7 parts of triethylenediamine.

[0025] Triethylenediamine is mixed with 50% ethanol whose mass is 8.2 times to prepare triethylenediamine solution; perillyl alcohol is mixed with ethanol whose mass is 1.1 times to prepare perillyl alcohol solution. Crush illite and pass through a 120 mesh sieve, then add triethylenediamine solution, raise the temperature to 73°C and seal and stir at this temperature for 2.2h, then raise the temperature to 88°C and add salicylic acid dropwise, after the dropwise addition is completed, in the Ultrasonic treatment at high temperature for 37 minutes, ultrasonic power 900W, then add perillyl alcohol solution and stir at 100°C until dry, then calcined in a muffle furnace at 440°C for 3.8h to obtain the desulfurizer.

Abstract

The invention discloses a gasoline desulfurization agent and a preparation method and application thereof. The gasoline desulfurization agent comprises, by weight, 21-29 parts of illite, 1-5 parts ofperillyl alcohol, 3-7 parts of salicylic acid and 5-12 parts of triethylene diamine. The preparation method includes: crushing the illite, adding a triethylene diamine solution, heating and stirring in a sealed manner, dropwise adding the salicylic acid, performing ultrasonic treatment, adding a perillyl alcohol solution, stirring until dryness is achieved, and calcining to obtain the desulfurization agent. The gasoline desulfurization agent has the advantages that RON loss of gasoline is allowed to be smaller than 2.0, and the ultralow-sulfur-content gasoline with the sulfur content being below 6 microgram / g can be obtained; the gasoline desulfurization agent is good in sulfur selectivity, high in desulfurization depth, capable of deeply removing sulfur-containing compounds in the gasoline and avoiding octane value loss caused by olefin hydrogenation saturation, long in service life, environmentally friendly, free of secondary pollution and good in regeneration performance. The preparation method is simple in process, easy in raw material obtaining, low in production cost and suitable for industrial production.

Description

[0001] This application is a divisional application with application number 2016111136235, application date of December 07, 2016, and invention name "a gasoline desulfurizer and its preparation method and application". technical field [0002] The invention relates to the technical field of gasoline, in particular to a gasoline desulfurizer and its preparation method and application. Background technique [0003] The sulfur compounds in gasoline will generate sulfur oxides SOx after combustion, which can poison the catalyst of the automobile exhaust gas conversion system, further affecting the effective conversion of NOx, CO, and CH, and the emission of sulfur oxides into the atmosphere will form acid rain and pollute the environment. As people pay more and more attention to environmental protection, environmental protection regulations are becoming stricter, and the global gasoline sulfur content indicators are becoming stricter. Similarly, my country's automotive gasoline ...
