Abstract
The present invention relates to a device for injecting a hydrocarbon charge into a catalytic cracking reactor comprising in particular an envelope (1), a main (liquid) charge feed tube (3), and an inlet (2) for an auxiliary gaseous fluid. According to the invention, charge feed tube (3) is divided, inside envelope (1), into at least two secondary lines (4) designed to distribute said charge uniformly, each secondary line (4) terminates coaxially with the inlet of an element (7) of the venturi type, and the auxiliary gaseous fluid is mixed with the charge at the inlet of said venturi (7). The present invention applies in particular to catalytic cracking of heavy hydrocarbon charges.
