摘要： Lithium-containing electrochemical energy storage devices a recycled by the following steps: i) The electrochemical energy storage devices are initially comminuted and a fraction comprising an active material is separated from the comminuted material. The fraction includes carbon (C), lithium (Li) and at least one of cobalt (Co), manganese (Mn), nickel (Ni), or iron (Fe). ii) The fraction comprising active material is subsequently fed to a melt-down unit and is melted down in the presence of slag-forming agents so that a molten slag phase and a molten metal phase are formed, iii) Then, the lithium (Li) contained in the molten slag phase and/or molten metal phase is converted into a gas phase by the addition of a fluorinating agent and the carbon (C) is converted into a gas phase by the addition of an oxygen-containing gas, and the lithium and carbon are withdrawn from the process as discharge gas.

摘要： A method for efficient disposal of dioxin and heavy metals based on calcium-based heat storage of MSWI fly ash is provided. According to the method, MSWI fly ash washed with water is treated with ammonia, and carbon dioxide is continuously introduced under stirring. The ammonia provides OH− for a carbonation reaction of the MSWI fly ash and promotes removal of sulfate ions. After centrifugation of a reaction solution, calcium carbonate obtained as a solid part is transported to a calcinator of a solar chemical heat reservoir and calcined into calcium oxide by means of solar energy obtained by a solar concentrator. CO2 produced in a calcination process is collected, cooled and liquefied, followed by a carbonation reaction with the calcium oxide in a carbonation radiator. After the operations above are repeated in cycles for several times, carbonated MSWI fly ash is obtained for use as an aggregate or a filler.

摘要： Disclosed is a battery recycling process wherein an electrochemical flow cell reactor is used to regenerate a reducing agent in an efficient manner. The reactor is decoupled from a hydrometallurgical process in which the reducing agent is used to promote the leaching and reduction of used battery materials in a stirred-tank reactor, such that these two potentially continuous reactors can be operated at independent rates. Since the electrochemical reactor effectively employs forced convective flow, it enables operation at high conversion rates with minimal overpotential and can also be preferentially operated when electrical energy is readily available while the stirred-tank reactor can be operated essentially continuously at a relatively low rate, which enables this equipment to be sized for the desired average energy consumption rate. These features reduce the capital and operation costs relative to electrochemical-based hydrometallurgical process systems taught by others.

摘要： A method of delamination of a printed circuit board includes comminuting the printed circuit board, and soaking the comminuted PCB in a solvent system comprising at least two solvents. Once soaking has been completed the method includes separating solids, and electrostatically separating different specific solids from the separated solids.
