    Abstract: A reactor for catalytic gas reactions such as synthesis of methanol or ammonia comprises at least one cylindrical catalyst bed having a height not greater than half its over-all diameter and defined on its underside by a grid supported by a dished plate having peripheral mechanical connection to a downward extension of the bed wall. Preferably there are several such beds and an indirect heat exchanger upsteam of the downstream-most bed. The reactor is suitably 5-10 m in diameter and is especially for use at under 120 bar abs in an integrated process for producing methanol and ammonia.

    Abstract translation: 用于催化气体反应的反应器例如合成甲醇或氨包括至少一个圆柱形催化剂床，该圆柱形催化剂床的高度不大于其全部直径的一半，并且在其下侧由网格支撑，该格栅由具有外围机械连接 床壁向下延伸。 优选地，存在几个这样的床和最下游床的间接热交换器上游。 反应器的直径合适为5-10微米，尤其是在120巴绝对压力下用于生产甲醇和氨的一体化方法。

    Abstract: The present invention relates to a process for the continuous preparation of polypropylene in a reactor from propylene and optionally ethylene and/or at least one other oolefin monomer, wherein the reactor comprises a fluidized bed, an expanded section located at or near the top of the reactor, a distribution plate located at the lower part of the reactor and an inlet for a recycle stream located under the distribution plate, wherein the process comprises—feeding a polymerization catalyst to the fluidized bed in the area above the distribution plate—feeding the propylene and the optional at least one other oolefin monomer to the reactor—withdrawing the polypropylene from the reactor—circulating fluids from the top of the reactor to the bottom of the reactor, wherein the circulating fluids are compressed using a compressor and cooled using a heat exchanger, resulting in a cooled recycle stream comprising liquid, and wherein the cooled recycle stream is introduced into the reactor using the inlet for the recycle stream wherein an alkane chosen from the group of iso-butane, n-butane, cyclopropane and mixtures thereof is added to the reactor and wherein the molar composition of the components in the recycle stream is chosen such that the dew temperature of the recycle stream at the reactor pressure is at least 0.10° C. below the temperature of the reactor

    Abstract: Reaction chamber liners for use in a fluidized bed reactor for production of polysilicon-coated granulate material are disclosed. The liners include an aperture and a cavity configured to receive a reactor component, such as a probe, a sensor, a nozzle, a feed line, a sampling line, a heating/cooling component, or the like. In some embodiments, the liner is a segmented liner comprised of vertically stacked or laterally joined segments, wherein at least one segment includes an aperture and a cavity configured to receive a reactor component.
