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

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 its preparation method and application. Background technique [0002] 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 standards have higher and higher requirements for sulfur content, which puts forward higher requirements for gasoline desulfurization technology of my country's oil refineries.
