  • Patent number: 10262765
    Abstract: The method according to the invention enables a facility having a rather reduced dimension, for incinerating to be used, melting and vitrifying mixed waste (30) introduced into a reactor (10), by means of a basket (18) in turn passing through an air lock (12). Plasma torches (14) burn all waste (30) contained in the basket (18). The waste is then lowered in a melting bath of a furnace (20) with an inductor (24) including a crucible-forming container (23). A combustion gas treatment train completes the facility. The furnace (20) can be dismantled, after a series of treatments of several baskets (18) of waste (30) for disassembling the crucible-forming container (23) from the furnace (20). Application in treating different radiologically contaminated and/or toxic mixed waste.

  • Patent number: 9719679
    Abstract: A basket for incinerating waste inside an incinerator for a duration longer than fifteen minutes with no need for waste to be molten earlier, particularly when waste is introduced inside the incinerator. The basket includes mainly of a glass fiber envelope: it is preferably stiffened by a lightweight metal structure located inside or outside the envelope or built into it. A gripping handle is installed on top of the assembly that is stiffened at the top by a metal tube to which a lightweight metal structure is fixed and by a base formed from a drip pan fixed to the base of the lightweight metal structure.

  • Publication number: 20100136442
    Abstract: The invention relates to a method for preparing hydrogen that comprises a hydrolysis step (C) of solid SnO for producing hydrogen, in which the hydrogen thus produced is stored, recovered and/or upgraded, and in which the solid SnO used is obtained by the following steps: (A) thermal reduction of SnO2 into SnO in conditions yielding gaseous SnO; and (B) cooling the gaseous SnO thus produced to a temperature lower than or equal to % 50° C. The invention also relates to devices and equipments for implementing said method.
