摘要:
The invention relates to a method for synthesising glycolic acid or one of the salts thereof, including the following step: placing glycerol and an oxidising agent in contact with one another in a reaction medium in the presence of a silver-based catalyst on a substrate, said substrate including a material selected from the group consisting of CeO 2 , basic Αl 2 Ο 3 optionally doped with a calcium or cerium oxide, an amphoteric resin, ZrO 2 , and a mixture of said materials. The invention also relates to the use of a silver-based catalyst on a substrate that can be used in said method.
摘要:
The invention relates to a device (1) for evaluation of at least one performance criterion of heterogeneous catalysts, comprising; at least one reactant source (2), at least one reaction zone equipped with at least one catalyst and connected to at least one reactant source (2) in such a way as to produce, in each reaction zone, a heterogeneous catalytic reaction between each catalyst present in the reaction zone and the reactant or reactants coming from each reactant source (2) connected to the reaction zone, and means for evaluation of at least one performance criterion of heterogeneous catalysts, characterized in that the device (1) further comprises a gas chromatograph and in that each reaction zone (9) is situated in an injector (8) of the gas chromatograph.
摘要:
The present invention relates to a method for producing hydrogen at a low temperature from alcohols without forming carbon, using a cerium and nickel oxyhydride material, and to the use of such a material as a catalyst for transforming alcohols into hydrogen.
