Method and device for removing solid catalyst

Used catalyst (500) is removed from a process microchannel (310) of a Fischer-Tropsch reactor by directing an air jet (4) from an air knife (1) through a slot of a protective element (2). The air knife traverses a continuous row of process microchannels (310) in a direction A. The spacer element (2)...

Beschreibung
Zusammenfassung:	Used catalyst (500) is removed from a process microchannel (310) of a Fischer-Tropsch reactor by directing an air jet (4) from an air knife (1) through a slot of a protective element (2). The air knife traverses a continuous row of process microchannels (310) in a direction A. The spacer element (2) protects the internal microchannel structure (315) of the process microchannel from damage by an air jet (4) that may approach or exceed sound velocity when directed into the process microchannel. 通过引导来自气刀(1)的空气射流(4)穿过保护元件(2)的狭槽，从费-托反应器的工艺微通道(310)中除去用过的催化剂(500)。气刀沿方向A横穿连续的工艺微通道(310)行。间隔元件(2)保护工艺微通道的内部微通道结构(315)免受可能在被引导到工艺微通道中时接近或超过音速的空气射流(4)的损害。
