    • The invention relates to a method and a device for the preparation of expanded thermoplastic microspheres from unexpanded thermally expandable thermoplastic microspheres comprising a thermoplastic polymer shell encapsulating a blowing agent. The method comprises: (a) feeding a slurry of such expandable thermoplastic microspheres in a liquid medium into a heating zone; (b) heating the slurry in the heating zone, without direct contact with any fluid heat transfer medium, so the expandable microspheres reach at least a temperature at which they would have started to expand at atmospheric pressure, and maintaining a pressure in the heating zone sufficiently high so the microspheres in the slurry do notfullyexpand; and, (c) withdrawing the slurry of expandable microspheres from the heating zone into a zone with a pressure sufficiently low for the microspheres to expand.
    • 本发明涉及一种从未膨胀的热可膨胀热塑性微球制备膨胀的热塑性微球的方法和装置,其包括封装发泡剂的热塑性聚合物壳。 该方法包括:(a)将这种可发性热塑性微球的浆液在液体介质中进料到加热区中; (b)加热加热区中的浆料,而不与任何流体传热介质直接接触,因此可膨胀微球体至少达到它们将在大气压下开始膨胀的温度,并保持加热区中的压力 足够高,使得浆料中的微球发生明显膨胀; 和(c)将可膨胀微球的浆料从加热区抽出到压力足够低以使微球膨胀的区域中。

    • The invention relates to a tube heat exchange reactor for carrying out an endothermic catalytic reaction. The tube heat exchange reactor comprises: an outer tube with a first and a second end, where the first end is an inlet end and where the second end is a closed end, an inner tube coaxially arranged within the outer tube and spaced apart from the outer tube, where at least a part of the inner tube holds a bed of catalyst material susceptible for induction heating and where the inner tube has an inlet end and an outlet end, an induction coil placed within the annular space confined between the outer and the inner tube, and a power source arranged to supply alternating current to the induction coil in order to generate an alternating magnetic field within at least a part of the inner tube. The tube heat exchange reactor is arranged to allow a process gas stream to be led into the inlet end of the outer tube and flows in the annular space confined between the outer and inner tube towards the second end of the outer tube and into the inner tube, where said process gas reaches the bed of catalyst material and undergoes an endothermic reaction resulting in a product gas.
