Seals for use with catalyst structures

Described herein are flexible seals for directing fluid flow in a tubular reactor, such as a reformer, for enhancing heat transfer and reactor efficiency. The seals can be made of corrugated metal foil that is expandable in the radial direction for accommodating the expansion and contraction of reactor components in the tubular reactor during operation. The seals can block or redirect fluid flow through the reactor. Fluid is directed to the interior of the reactor by the seals and bypass around the outer circumference of the reactor components is reduced or eliminated. 本文描述了种用于引导反应器管、比如重整器中的流体流的柔性密封件，用于增强传热和反应器效率。密封件能够由波纹状金属箔制成，所述波纹状金属箔能够沿着径向方向扩展，用于适应管状反应器中的反应器部件在操作期间的扩展和收缩。密封件能够阻塞或者重定向通过反应器的流体流。通过密封件将流体引导至反应器内部并且减少或者消除绕过反应器部件的外圆周周围的流体。
