Abstract: Process for recycling a fiber reinforced polymer article, according to which the article, eventually cut in fragments, is dissolved in a solvent capable of dissolving the polymer but not the fibers and which is susceptible of forming an azeotrope with water, forming a solution; the fibers are recovered from the solution; the fibers are washed with solvent by putting them in the form of a slurry in the solvent and by agitating the slurry and/or by making the solvent circulate through it; the washed fibers are recovered from the slurry; and the recovered fibers are submitted to a stripping with steam in order to substantially remove the solvent.

Abstract: Process for the manufacture of an aqueous solution of hydrogen peroxide by direct synthesis from hydrogen and oxygen in a three-phase system, according to which hydrogen and oxygen are reacted directly in the gaseous state at the surface of a solid heterogeneous catalyst, the reaction being performed continuously in a reactor with a stationary trickle bed, filled with solid catalyst particles forming the stationary bed through which a liquid consisting of an aqueous solution and the gas phase containing the hydrogen and oxygen are made to trickle concurrently.

Abstract: Method for the direct synthesis of an aqueous solution of hydrogen peroxyde from hydrogen and oxygen by hydrogenous catalysis in a three-phase system in which the hydrogen and oxygen are reacted directly in a gas state, at a pressure above atmospheric pressure, on the surface of a solid hydrogenous catalyst in suspension in a granular state in an aqueous liquid phase, said catalyst consisting of a metal compound selected from pure palladium or an association of palladium with at least one other noble metal, and impregnated on a substrate comprising at least one compound selected from alkaline-earth metal sulfates or phosphates. A catalyst is disclosed for the production of an aqueous liquid phase of hydrogen peroxyde consisting of a metal compound selected from pure palladium or an association of palladium with at least one another noble metal, and impregnated on a substrate comprising at least one compound selected from alkaline-earth metal sulfates or phosphates.
