Abstract: A catalyst retainer includes an inner particle retention device having apertures and a first non-apertured section; and an outer particle retention device having apertures and a second non-apertured section. The inner and the outer particle retention devices are spaced apart to define a particle retaining space of the retainer. The first non-apertured section and the second non-apertured section define a blanked-off section of the particle retaining space, and the blanked-off section is spaced from an end of the particle retaining space. The catalyst retainer also includes a louver with at least a portion located between the blanked-off section and the end of the particle retaining space. The louver extends into the particle retaining space at an angle with respect to an inner surface of the inner particle retention device. The louver introduces the fluid to the top catalyst free surface in a more uniform manner and hence prevents particle movement and attrition.

Abstract: A reforming reactor and process of using same in which the process gas is effectively and efficiently distributed through the non-reactive zone. The non-reactive zone has two portions, a first portion receiving a purge gas and having an outlet for an effluent from a reactive zone disposed beneath the non-reactive zone and a second portion receiving the feed and having an inlet. The inlet is located between the reaction zone and the outlet. A flow distributor separates the non-reactive zone into the two portions.

Abstract: Processes and apparatuses for relocating a reforming process heater service into the convection section rely on combining a flue gas recycle quench stream with the radiant section off gases entering the convection section. The uniformity of mixing influences the effectiveness of that quench stream. The more effective the quench stream is, the lower the equipment size required to manage the recycle design.
