  • Method to regenerate oxygen traps
    Patent number: 10428433
    Abstract: A method is described to regenerate an oxygen trap, comprising at least the following steps: circulating a current in the trap material (2) to reduce this material; measuring the value Im of the current and estimating its derivative dIm/dt in relation to time; estimating the length (?) of material reduced by the current as a function of the value of the current and its derivative; stopping circulation of the current when the length of reduced material is at least equal to a threshold value (?s).
    Type: Grant

  • METHOD TO REGENERATE OXYGEN TRAPS
    Publication number: 20160177458
    Abstract: A method is described to regenerate an oxygen trap, comprising at least the following steps: circulating a current in the trap material (2) to reduce this material; measuring the value Im of the current and estimating its derivative dlm/dt in relation to time; estimating the length (?) of material reduced by the current as a function of the value of the current and its derivative; stopping circulation of the current when the length of reduced material is at least equal to a threshold value (?s).

  • Process for preparing a composite electrolyte based on BIMEVOX and the use of said compound in separating oxygen from a gas mixture
    Patent number: 6207038
    Abstract: A process for preparing a solid composite electrolyte comprising at least one compound of the BIMEVOX family is provided. The process comprises at least one step of preparing a mixture of one or more compounds of the BIMEVOX family with one or more chemically inert compounds, at least one step of compacting the mixture obtained, and at least one sintering step during which the temperature reached, over a nonzero time interval, has a value greater than the optimum sintering temperature for the compound of the BIMEVOX family.
