CATALYTIC REACTOR WITH DOWNFLOW Russian patent published in 2010 - IPC B01J8/04 

FIELD: oil-and-gas production.

SUBSTANCE: proposed reactor has set of catalyst layers for gas-and-fluid mix to pass therein. Zone between consecutive layers of catalyst incorporates distribution system to distribute and mix gas and fluid before contact with the next catalyst layer. Gas delivery line is arranged below tray with catalyst. Collection tray is suitable for reception of gas and fluid. Dain manifold extend above said collection tray. Mixing chamber is suitable for intake of water and gas flowing down from said drain manifolds. Baffle is arranged below mixing chamber. First distribution tray is arranged below said baffle and furnished with holes and tubes all over its length. At least one of the tubes incorporates distribution device to divide tube inner space into two spaces. Second distribution tray is arranged below the first one to redistribute gas and fluid before contact with the next catalyst layer.

EFFECT: improved mixing plus preserved swirled motion.
