METHOD AND APPARATUS FOR MIXING TWO CATALYST STREAMS Russian patent published in 2016 - IPC B01J37/04 B01J8/18 C10G11/18 

FIELD: chemistry.

SUBSTANCE: method of mixing two catalyst streams, which includes feeding a first catalyst stream, which is a stream of regenerated catalyst, into a chamber; feeding a second catalyst stream, which is a stream of carbonised catalyst, into a vertical riser; passing the catalyst from said chamber into said vertical riser; and passing said first catalyst stream and said second catalyst stream upwards through said vertical riser. An apparatus for mixing two catalyst streams, which includes a vertical riser; a first catalyst conduit linked to the vertical riser; a second catalyst conduit linked to the vertical riser; a chamber in said vertical riser, linked to said first catalyst conduit; and a wall of said chamber, which is situated at a distance from the wall of said vertical riser, wherein the first catalyst conduit and the second catalyst conduit are connected to the vertical riser.

EFFECT: enabling the mixing of two catalyst streams in order to reduce temperature difference of the streams before contact with hydrocarbon raw material.
