    Abstract: processo para oxidação parcial em fase gasosa fieterogeneamente catalisada. um processo para oxidação parcial em fase gasosa heterogeneamente catalisada, de um composto de partida orgânico, sobre um leito de catalisador fixo recém-instalado em uma câmara de reação, em que a redução da qualidade do leito de catalisador fixo é restaurada com o aumento do tempo de operação, mediante substituição de parte do leito de catalisador fixo por um leito de catalisador fixo parcial de substituição cuja atividade específica do voluma seja menor do que a atividade específica do volume do leito de catalisador fixo parcial substituído em seu estado recém-instalado.

    Abstract: Die vorliegende Erfindung betrifft eine Kolonne (1) zur thermischen Behandlung von fluiden Gemischen mit einem zylindrischen, vertikal ausgerichteten Kolonnenkörper (2), der einen Kolonnenhohlraum (3) bildet, mehreren Böden (8), die vertikal beabstandet voneinander in dem Kolonnenhohlraum (3) montiert sind, und einer Tragekonstruktion (9), die zumindest einen der Böden (8) in vertikaler Richtung stützt. Die erfindungsgemäße Kolonne (1) ist dadurch gekennzeichnet, dass die Tragekonstruktion (9) mehrere Öffnungen (12) aufweist, die einen horizontalen Stoffaustausch durch die Tragekonstruktion (9) erlauben. Ferner betrifft die Erfindung eine Bodeneinrichtung für eine solche Kolonne und ein thermisches Trennverfahren zwischen wenigstens einem in einer solchen Kolonne (1) aufsteigenden Gas und wenigstens einer in der Kolonne (1) absteigenden Flüssigkeit.

    Abstract: Preparation of a catalyst consisting of a carrier body and a catalytic active mass, which is applied on the surface of the carrier body, comprises attaching one of the active mass to the surface of the carrier body with the help of a binding agent, where the active mass is a finely divided mixture of: at least an element of molybdenum and vanadium containing finely divided multielement oxides; and at least a finely divided substance comprising oxide of molybdenum or its compound, which forms its oxide under the effect of increased temperature and molecular oxygen. An independent claim is included for a catalyst, obtained by the above process.

    Abstract: Mixing a liquid or suspension beneath a gas space in a closed container comprises supplying a stream of the liquid or suspension as a drive jet for a submerged ejector which aspirates gas from the gas space and discharges the gas together with the drive jet into the liquid or suspension in the container. Independent claims are also included for: (1) container comprising a liquid or suspension beneath a gas space and an ejector with a drive nozzle and a suction chamber in communication with the gas space; (2) container comprising a liquid or suspension beneath a gas space and an ejector jet nozzle having a drive nozzle surrounded by a suction chamber discharging into a mixing nozzle and an impulse exchange chamber into which the outlet of the mixing nozzle is directed, and a connection between the suction chamber and the gas space; (3) ejector jet nozzle having a drive nozzle surrounded by a suction chamber discharging into a mixing nozzle and an impulse exchange chamber into which the outlet of the mixing nozzle is directed, where the transition between the mixing nozzle and the impulse exchange chamber is provided with a jacket fitted with a dip pipe or a connector for a dip pipe; (4) mixing a liquid or suspension beneath a gas space in a closed container by supplying a stream of another liquid or suspension as a drive jet for a submerged ejector which aspirates gas from the gas space and discharges the gas together with the drive jet into the liquid or suspension in the container.
