The invention discloses a chlorine-containing pyrolysis oil radial moving bed reaction adsorption dechlorination hydro-conversion method, and belongs to the technical field of chlorine-containing oil product hydrotreatment and refining. According to the method, chlorine-containing pyrolytic oil is sequentially subjected to fixed bed selective hydrogenation, radial moving bed reaction adsorption dechlorination and fixed bed deep hydrofining reactor treatment; the radial moving bed is filled with a core-shell structure reaction and adsorption integrated catalyst, the core is a hydrodechlorination active component, the shell mainly adopts zinc oxide to adsorb HCl and is fixed in situ, and meanwhile, online addition and discharge of the catalyst are realized through the radial moving bed. According to the invention, poisoning of chlorine to the catalyst is effectively inhibited, the corrosion risk of equipment is reduced, shutdown of the device is avoided, the dechlorination efficiency is improved, the continuous operation period is prolonged, efficient, stable and economical hydro-conversion of the chlorine-containing pyrolytic oil is realized, and the obtained product can be used as clean fuel oil or a chemical raw material.

The application provides an electrolyte infiltration method. The electrolyte infiltration method comprises the following steps: S1, cooling a roasted battery cell; S2, placing the cooled lithium ion battery cell in a vacuum environment, and then introducing carbon dioxide gas; S3, introducing the battery cell into a liquid injection process, performing vacuum extraction treatment, and then performing liquid injection treatment; S4, pressure treatment; S5, vacuum extraction treatment; S6, repeating steps S4-S5 at least once; S7, introducing a protective gas to atmospheric pressure, adding a carbon dioxide additive to the battery cell after liquid injection, and obtaining an electrolyte-infiltrated battery cell. The electrolyte infiltration method provided by the application ensures that the electrolyte is fully infiltrated into the small pores inside the lithium ion battery, the infiltration time is short, high-temperature storage is not required, the production efficiency of the lithium ion battery is improved, and the electrochemical performance of the lithium ion battery is improved.
