FIELD: chemistry.
SUBSTANCE: invention relates to petrochemistry and organic synthesis. Catalyst and transport gas distributor in reactor and/or regenerator for dehydrogenation of C3-C5 paraffin hydrocarbons or synthesis of butadiene from ethanol with fluidised bed of catalyst and sectioning grids includes located along the reactor axis and/or regenerator, a vertical transport pipe connected to an expander installed coaxially on its upper end and connected to drain risers, the lower ends of which are located in the upper part of the fluidised catalyst bed. At that, the expander is made in the form of a truncated cone, on the lower end of each drain stand there is a baffle plate, and in the wall of each riser there are slots starting from the lower end of the riser. Distributor is characterized by certain ratios of dimensions of structural elements.
EFFECT: high efficiency, ease of manufacture and reliability in operation.
