FIXED OR MOVING BED REACTORS CONTAINING INTERNAL DEVICES AND RADIAL FLOW PROCESSED PROCESS FLOW Russian patent published in 2022 - IPC B01J8/02 B01J8/06 B01J8/08 B01J8/12 C01C1/04 C10G35/04 C10G35/12 C10G45/58 C10G45/66 

FIELD: machine building.

SUBSTANCE: invention relates to reactors with a movable or fixed bed with a radial flow of the processed process stream in the processes of catalytic reforming of gasolines, skeletal isomerisation of gasolines, exchange disproportionation of olefins, oligocracking, dehydrogenation of paraffins or aromatic compounds, production of ammonia. Reactor with radial flow of processed process stream comprises shell 5, means for input of processed process stream 4 and output of exit streams 11, zone of distribution of said process stream 9, if necessary, catalyst feed branch pipes 6, outer 3 and inner 2 grids, allowing the processed process stream to move from outer grid 3 to inner grid 2, located substantially in the center of the reactor, or vice versa from inner grid 2 to outer grid 3, wherein reactor also comprises at least one additional outer grid 13, 18, having a shape adapted to the shape of the bottom part of the reactor or the top part of the reactor, wherein additional grid 13, 18 is located as a continuation of outer grid 3.

EFFECT: such an arrangement enables to reduce the volume of the BI zone in the area of the reactor bottom, which is an ineffective ("dead zone"), that is, to minimize catalytic zones into which the processed process stream does not enter, which provides a gain in overall efficiency of the reactor.
