Problems solved by technology

Moreover, the hydrogen sulfide in the product may further react with olefins to generate mercaptans, and the organic sulfur content of the product after hydrogenation is difficult to be lower than 0.5ppm
Due to the existence of these hydrogen sulfide removal devices, the desulfurization reactor cannot be directly connected in series with the aromatics removal reactor, and the raw material and hydrogen need to be reheated before entering the second-stage aromatics removal reactor, which wastes a lot of energy. In order to solve the above technical problems, A new technical solution is proposed

Abstract

The invention discloses a waste mineral oil hydrogen adsorption desulfurization method, relates to a desulfurization process. The method comprises the following steps: Step 1: catalyst treatment: first placing a catalyst in a vessel A, then adding an organic solvent to the vessel A, and stirring the catalyst and the organic solvent through a stirring device to make the catalyst and the organic solvent into a mixed solution; Step 2: raw material processing: placing a raw material into a placing tank, then adding a diluent to the placing tank, diluting the raw material through the diluent, and simultaneously, stirring a mixture of the raw material and the diluent in the placing tank through the stirring device; Step 3: adsorption desulfurization: pouring a mixed solution of the diluent and the raw material in second step into a vessel B. The adsorption desulfurization method has the advantages of simple production process and simple using equipment, lower production cost, and suitable for large-scale production. Hydrogen sulfide will not be produced during a process of adsorption desulfurization. At the same time, the reaction is carried out under normal temperature conditions, and no waste of resources generates.

Description

technical field [0001] The invention relates to a desulfurization process, in particular to a waste mineral oil hydrogenation adsorption desulfurization method. Background technique [0002] Along with the raising of the 6# solvent oil quality requirement that the country uses for edible oil extraction, the aromatic hydrocarbon content index in the 6# solvent oil is reduced to 0.1% from 1%, now industrially produces 6# solvent oil technology to reach this index to have certain difficulty. The raw materials for producing 6# solvent oil are generally aromatic hydrocarbon raffinate, straight-run gasoline or oilfield condensate oil. Now the solvent used in industrial extraction of aromatic hydrocarbon is sulfolane, and aromatic hydrocarbon raffinate inevitably contains a certain amount of organic Sulfur compounds are also present in straight-run gasoline and oil field condensate. Since the hydrogenated hydrogen generally also contains 0.5ppm of inorganic sulfur, these sulfides...
