    • Improved apparatus for use in process systems which include exothermic chemical conversions of organic compounds to value added products is disclosed, more particularly, flow reactors for exothermic chemical conversions using a fixed heterogeneous catalyst with means for control of the exotherm. Flow reactors of the invention comprise a plurality of walled conduits each having an outer surface disposed for contact with a heat-transfer medium, an inlet distribution manifold adapted for flow communication with a downstream manifold through channels formed by heterogeneous catalytic material disposed within each conduit during operation in a sequence of zones for catalyst having the same or different length along the longitudinal coordinate of the conduit and within each zone essentially uniform cross-section of the conduit measured in a plane perpendicular to the longitudinal coordinate thereby defining volume of the zone, and the sequence of zones comprising of at least two zones such that each downstream zone has a larger or smaller cross-section than the contiguous upstream zone. Another aspect of the invention includes processes which use such flow reactors, for example the continuous manufacture of maleic anhydride.
    • 公开了一种改进的用于工艺系统的装置,其包括有机化合物对增值产物的放热化学转化,更具体地,涉及使用具有用于控制放热的装置的固定多相催化剂的放热化学转化的流动反应器。 本发明的流动反应器包括多个壁管道,每个管道具有被设置用于与传热介质接触的外表面,适于通过设置在每个管道内的非均相催化材料形成的通道与下游歧管流动连通的入口分配歧管 沿着导管的纵向坐标具有相同或不同长度的催化剂区域序列的操作,并且在每个区域内,在垂直于纵向坐标的平面中测量的管道基本上均匀的横截面,从而限定区域的体积,以及 所述区域序列包括至少两个区域,使得每个下游区域具有比所述连续上游区域更大或更小的横截面。 本发明的另一方面包括使用这种流动反应器的方法,例如连续制造马来酸酐。
