Abstract
The invention provides an organic sulfide removal agent. The organic sulfide removal agent comprises a carrier and an active component, wherein the active component is supported on the carrier through an impregnation method; the carrier comprises an HY molecular sieve and a NaY molecular sieve; the active component is nitrate which comprises silver nitrate and lithium nitrate. By virtue of the removal agent, sweat flow polar organic compounds are removed from gasoline by an absorption manner; even if the removal agent is inactivated, the removal agent can be regenerated by a method of washing with a solvent or heating, so that the organic sulfide removal agent can be theoretically durable and effective during the quality guarantee period.
Description
Technical field
The present invention relates to chemical field, particularly a kind of organic sulfur compound removes agent.
Background technology
Along with world wide environmental requirement increasingly stringent, people require also more and more harsher to petroleum product-quality, especially form SO to after burning
2, SO
3, water is combined and is formed acid mist, acid rain and have a strong impact on the sulfide content restriction of ecological environment and people's daily life in atmosphere then.Countries in the world have proposed more and more stricter restriction to the sulphur in fuel oil, carry out in order to meet people to the high-quality requirement of oil product and to safeguard that production safety is stable, and the each manufacturing enterprise of petrochemical industry updates the desulfurization work gas in production process.
The sulfide relating in petrochemical production process can be divided into inorganic sulphide and organic sulfur compound, inorganic sulphide is easier to remove, but the removal methods of organic sulfur compound is also in the middle of further developing, the method removing for organic sulfur compound in current technology comprises hydro-conversion, biological eliminating technology, excusing from death mother-in-law desulfurization, zeolite desulfurization, liquid phase adsorption desulfurization, ionic liquid desulfurization etc., but each technology is no matter from effect or cost consideration need to improve.
Summary of the invention
Technical problem to be solved: the invention provides a kind of organic sulfur compound for above problem and remove agent.
Technical scheme: in order to overcome the above problems, to the invention provides a kind of organic sulfur compound and remove agent, comprising: carrier and active component; Described active component is by loading on carrier with infusion process; Described carrier comprises HY molecular sieve and NaY molecular sieve; Described active component is nitrate, and nitrate comprises silver nitrate, lithium nitrate.
Further technical scheme, described carrier should be immersed in the 1-2 month in middle strong acid or strong acid before supported active composition, and the region of described middle strong acid is 250-350 DEG C, and the region of described strong acid is 450-550 DEG C.
Further technical scheme, use infusion process by active constituent loading on carrier time, the temperature that bakes in its preparation process is 350 DEG C.
Further technical scheme, in the time that the active component of load on carrier is larger, selects HY molecular sieve as carrier; In the time that the active component of load on carrier is less, select NaY molecular sieve as carrier.
Further technical scheme, described active component is silver nitrate.
Beneficial effect:
1, the agent that removes in the present invention adopts the mode of adsorbing from gasoline, to remove the polar organic compound of sweat stream, even if remove agent inactivation, also can be by make its regeneration by the method for solvent washing or heating, so be can be effective for a long time in theory aspect the shelf-life.
2, in the present invention, select carrier to be immersed in middle strong acid or strong acid environment, can significantly improve the adsorption effect that removes agent.
3, in the present invention, remove in the process of agent baking the strict control of temperature in preparation, can make the metal ion difficult drop-off in agent that removes after preparation, improved adsorption effect.
