    Abstract: The invention relates to a method for the production of formaldehyde by gas phase oxidation of methanol vapour with a gas flow containing a molecular oxygen in the presence of solid bed catalyst containing iron and molybdenum. The invention is characterised in that the method is carried out in a reacto r (1) comprising thermal sheet metal plates (2) which are arranged at a distan ce from each other and in the longitudinal direction of the reactor (1), said thermal sheet metal plates being cross-flown by a heat carrier. The reactor also comprises devices for supplying and withdrawing (3, 4) the heat carrier to/from the thermal sheet steel plates (2), and gaps (5), which are disposed between the thermal sheet steel metal plates (2) and which are filled with t he solid bed catalyst and are introduced into the gas flow containing the methanol vapour and the molecular oxygen.

    Abstract: Preparation of chlorine involves passing hydrogen chloride and gas stream comprising molecular oxygen in a reactor (1) having parallel catalyst tubes (2) charged with fixed-bed catalyst and at least one deflector plate (6) perpendicular to the reactor. The plates leave passages on opposite sides of the reactor free next to its interior wall. A liquid heat transfer medium circulates between tubes.

    Abstract: Se divulga un metodo para la produccion de cloro por medio de oxidacion en fase gaseosa de cloruro de hidrogeno con un flujo de gas que contiene oxigeno molecular en presencia de un catalizador de cama fija. Dicho metodo se lleva a cabo en un reactor (1) que comprende un conjunto de tubos de contacto (2) colocados paralelos entre ellos en la direccion longitudinal del reactor y sujetados en fondos de tubos (3) en sus extremos, una campana (4) colocada en ambos extremos del reactor (1), y una o varias laminas metalicas de desviacion (6) colocadas perpendicularmente a la direccion longitudinal del reactor en el espacio intermedio (5) entre los tubos de contacto (2) y liberan alternadamente los pasajes opuestos (7) ubicados en la pared interna del reactor (1). Los tubos de contacto (2) se llenan de catalizador de cama fija, el cloruro de hidrogeno y el flujo de gas que contiene oxigeno molecular dirigidos desde un extremo del reactor a traves de los tubos de contacto (2) a traves de una campana (4) y son retirados del extremo opuesto del reactor a traves de la segunda campana (4), y una sustancia liquida de intercambio de calor es dirigida a traves del espacio intermedio (5) alrededor de los tubos de contacto (2).

    Abstract: The invention relates to a process for carrying out exothermic chemical equilibrium reactions in a fluidized-bed reactor, wherein there is a temperature distribution in the fluidized bed of the fluidized-bed reactor and the temperature difference between the lowest temperature and the highest temperature is at least 10 K. The invention further relates to a fluidized-bed reactor for carrying out chemical reactions in a fluidized bed ( 5 ), wherein at least one heat exchanger ( 12, 28 ) is located in the fluidized bed ( 5 ) to control the temperature distribution.
