PURPOSE: A desorption material for a continuous sulfur oxide adsorption removal process and a method consecutively removing a sulfur oxide from a hydrocarbon stream using the same are provided to efficiently remove a sulfide from a hydrocarbon stream by maintaining the sulfur oxide adsorption quantity of an adsorption material highly in a continuous process repeating the adsorption and desorption of the sulfur oxide. CONSTITUTION: A desorption material for a continuous sulfur oxide adsorption removal process includes any one selected from a DME (dimethyl ether), a DMC (dimethyl carbonate), and a MTBE (methyl tertiary butyl ether), and a mixture thereof. The desorption material additionally includes hexane or benzene. The desorption is performed at 40~90>=, 1~20barg. The vaporization latent heat of the desorption material is below 500 kJ/kg. The boiling point is 120>= or less which is a sulfide oxidation temperature. A method consecutively removing a sulfur oxide from a hydrocarbon stream includes following steps. A step for absorbing the sulfur oxide from a hydrocarbon stream by using an adsorption material selectively adsorbing the sulfur oxide; a step for reproducing the adsorption material by detaching the adsorbed sulfur oxide with the desorption material; and a step for reusing by separating a desorption material from the detached sulfur oxide and the mixture of the desorption material. |
