Abstract:
Beschrieben wird ein Trägerkatalysator auf Basis von Aluminiumoxid, enthaltend a) Palladium als hydrieraktives Metall und b) Silber und Scandium als zusätzliche Promo- toren und Verfahren zur Selektivhydrierung ungesättigter Verbindungen in Kohlenwasserstoffströmen unter Verwendung dieser Katalysatoren.
Abstract:
Verfahren zur Isomerisierung von linearen alpha-Olefinen mit 10 bis 25 C-Atomen an einem heterogenen Katalysator, dadurch gekennzeichnet, dass der Katalysator Palladium und Selen und/oder Tellur auf einem Träger enthält.
Abstract:
The invention relates to a method and a device for putting into service a reactor and a catalyst, especially a catalyst and a reactor for dehydrogenating a hydrocarbon-containing charge in a plant for producing olefins. Before being put into service, the catalyst and the reactor run through a plurality of oxidation and reduction phases, thereby releasing the chloride contained in the catalyst. The released chloride is carried off into the atmosphere in a gaseous form.
Abstract:
The invention relates to a method and a device for the controlled regeneration of a catalyst and of a fired reactor, especially a catalyst and a reactor in a plant for producing olefins from a hydrocarbon-containing charge. During the regeneration phase of the catalyst for recovering the catalytic activity, the burners of the reactor are switched off. After the regeneration phase, the burners are re-ignited by means of inbuilt pilot burners. The pilot burners are monitored and their capacity is adjusted in such a manner that the heat loss of the reactor during the regeneration phase of the catalyst is compensated for.
Abstract:
The invention relates to a method for isomerizing alpha olefins having 10 to 25 C atoms using a heterogeneous catalyst, characterized in that the catalyst comprises palladium and selenium and/or tellurium on a carrier.
