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.
