Process and apparatus for catalytic cracking of a hydrocarbon charge in a fluid bed comprising the introduction of the charge mixed with a gaseous auxiliary fluid by means of at least one venturi-type device (5), whose axis is essentially parallel to the axis of the reaction region, said device (5) comprising at its first end means for introducing the filler and the auxiliary fluid and its other end an element comprising an opening, and defining a restriction in the section of said end, through which said mixture is fed into said reaction zone (4). The reactor (1) comprises means for introducing the catalyst and means (3) for introducing the fluid gas. The reactor preferably comprises a plurality of devices (5). |
