Polymerization of alk-1-ene in a stirred powder bed, e.g. for production of polypropylene, involves polymerization in presence of a fluid-bed classifier formed by passing gas upwards through an open tube in the powder
A method for the gas-phase polymerisation of 2-8C alk-1-enes at 40-150 deg C and 1-100 bar in a stirred powder bed using a suitable catalyst system involves polymerization in presence of a fluidized-bed classifier consisting of an open tube in the powder bed through which gas is passed upwards at su...

| description | A method for the gas-phase polymerisation of 2-8C alk-1-enes at 40-150 deg C and 1-100 bar in a stirred powder bed using a suitable catalyst system involves polymerization in presence of a fluidized-bed classifier consisting of an open tube in the powder bed through which gas is passed upwards at such a rate that a fluidized bed is formed in the powder-filled tube. An Independent claim is also included for a device for the above process, comprising a stirred powder-bed reactor incorporating fluid-bed classifier(s) in the form of tube(s) open at the top and bottom and fitted with a gas inlet in the lower half of the tube.
Verfahren zur Polymerisation von C¶2¶-C¶8¶-Alk-1-enen mit Hilfe eines geeigneten Katalysatorsystems, wobei aus der Gasphase heraus in einem gerührten Pulverbett bei Temperaturen von 40 bis 150 DEG C und Drücken von 1 bis 100 bar polymerisiert wird, dadurch gekennzeichnet, daß die Polymerisation in Anwesenheit wenigstens eines Wirbelschichtklassierers erfolgt, der ein nach oben und nach unten hin offenes Rohr darstellt, welches im gerührten Pulverbett eingebaut ist, wobei durch das Rohr von dessen unterer Hälfte her Gas mit einer derartigen Geschwindigkeit zum oberen Ende geleitet wird, daß sich in dem Pulver gefüllten Rohr ein Wirbelbett bildet. |
