Method for simultaneously removing sulfides in gasoline and liquefied gas through double reactors

A method for simultaneously removing sulfides in gasoline and a liquefied gas through double reactors is characterized in that a gasoline raw material and hydrogen enter a first adsorption reactor from the bottom, flow from bottom to top, and contact with a desulphurization adsorbent in the first adsorption reactor to adsorb and remove sulfides in gasoline; the reacted oil gas and the desulphurization adsorbent are separated at the upper portion of the first adsorption reactor, the separated desulphurization adsorbent undergoes pressure transition and is introduced into a second adsorption reactor, and a sulfur-containing liquefied gas enters the second adsorption reactor from the bottom and contacts with the low-activity desulphurization adsorbent in order to adsorb and remove sulfides in the liquefied gas; and the high-sulfur-content adsorbent to be regenerated reacted with the liquefied gas is separated from the oil gas, is leaded out of the second adsorption reactor, enters a fluidized bed regenerator, and is scorched and regenerated, and the regenerated adsorbent is reduced and is returned to the first adsorption reactor for cycle use. The method provided by the invention maximally utilizes the activity of the desulphurization adsorbent to deeply adsorb and remove the sulfides in the gasoline, and utilizes the residual desulphurization capability of the adsorbent to adsorb and remove the sulfides in the liquefied gas.
