Abstract

La invencion se refiere a un procedimiento para llevar a cabo reacciones en fase gaseosa que se llevan a cabo sobre un lecho de catalizador con catalizador en forma de partículas, hallándose dispuesta en la direccion de la circulacion del gas una capa hecha de elementos sobre el lecho del catalizador, por lo que dicha capa hecha de elementos impide que las partículas del catalizador se arremolinen y fluyan de regreso, y los elementos de capa presentan una resistencia a la corrosion y a las altas temperaturas, por lo que las mismas representan un dispositivo de retencion libre de trastornos también bajo altas temperaturas. La invencion se refiere también a un dispositivo que consiste en elementos de capa permeables a los gases, que es adecuado para recubrir un lecho de catalizador consistente en partículas del catalizador, por lo que dicho lecho es impermeable frente a las partículas del catalizador.The invention relates to a process for carrying out gas phase reactions that are carried out on a catalyst bed with a particulate catalyst, a layer made of elements on the bed being arranged in the direction of gas circulation of the catalyst, whereby said layer made of elements prevents the catalyst particles from swirling and flowing back, and the layer elements have a resistance to corrosion and high temperatures, whereby they represent a retention device free of disorders also under high temperatures. The invention also relates to a device consisting of gas permeable layer elements, which is suitable for coating a catalyst bed consisting of catalyst particles, whereby said bed is impermeable against catalyst particles.
