DISTRIBUTING DEVICE FOR GAS-LIQUID FLOW IN A FIXED CATALYST BED Russian patent published in 2023 - IPC B01J8/10 B01F27/51 B01F27/1125 

FIELD: chemical technology.

SUBSTANCE: invention relates to the field of processes and apparatuses of chemical technology and can be used for hydro-catalytic processes in a fixed catalyst bed. A distributing device is described in the form of a rod made of a metal pipe with two blades wound around it, located symmetrically with respect to the axis of the rod, the device is located directly in the layer of solid particles of the catalyst, coaxial to the reactor and along the entire length of the layer, the blades and the rod of the distributing device are made in the form of separate sections, the sections are fastened to the beams, support rings and to each other by fastening clamps, while the reactor additionally comprises an upper "glass-in-glass" distributing device, a bubble cap-type distributing plate, as well as a layer of ceramic inert material and a support table.

EFFECT: elimination of non-uniformity of flow rates in the fixed layers of catalysts of the working chamber of the axial reactor and improvement of the surface interaction of the raw mixture with the catalyst.
