  • Patent number: 12220689
    Abstract: Disclosed is a process whereby completed catalysts can be produced from the iron oxides, and these catalysts can be activated and employed directly after activation for ammonia synthesis from synthesis gas, comprising for example a mixture of nitrogen and hydrogen. A process is also disclosed to produce pre-reduced catalyst precursors, which are first reduced under controlled conditions and subsequently passivated in an oxidizing atmosphere, before they are used in ammonia synthesis as catalysts. These pre-reduced catalysts can be activated significantly more quickly and under milder conditions than the iron oxides.

  • Publication number: 20250001379
    Abstract: A reactor for the catalytic production of methanol having two or more reaction zones arranged and surrounded by a heat exchange fluid. The reaction zones are preferably reaction tubes, and each reaction zone has at least one cleaning layer and at least one catalyst layer, where the cleaning layer is arranged upstream, and the catalyst layer is arranged downstream. A method for the catalytic production of methanol from synthesis gas using the reactor is also described.

  • Publication number: 20200055019
    Abstract: The present invention relates to an improved adsorbent for separating para-xylene from a mixture of xylene isomers, characterized in that the adsorbent contains a barium-containing zeolite of the faujasite type whose exchangeable sites are occupied to an extent of at least 4.0% by magnesium ions. The present invention additionally relates to the production of the adsorbent and to the use thereof in the separation of para-xylene from a mixture of xylene isomers.
