FIELD: petrochemical industry; devices and methods for realization of the catalytic cracking processes in the fluidized layers. ^ SUBSTANCE: the invention is pertaining to the field of petrochemical industry, in particular, to the reaction chamber for catalytic cracking process in the fluidized layer and the method of realization of the catalytic cracking in the fluidized layer. The reaction chamber contains in its upper part a means for separation of the catalytic agent particles from the product of the diluted phase delivered through a vertical pipe of the reaction chamber. The means of the separation are connected by the fluid medium to the pressure branch pipe of the vertical pipe of the reaction chamber and also are connected by the fluid medium to the devices for withdrawal from the chamber of the purified product delivered through a vertical pipe of the reaction chamber and are connected by the fluid medium to the devices for withdrawal of the separated catalytic agent into the lower part of the chamber. The reaction chamber in its lower part contains the devices for withdrawal of the catalytic agent from it. Between a side wall of the reaction chamber and a means for separation of the catalytic agent there is a protective jacket placed so, that it forms an external space between the reaction chamber wall and the protective jacket and the internal space inside the protection jacket. The internal space is freely communicating with the lower part of the reaction chamber, and the external space and the internal space communicate to each other through a hole. The reaction chamber has the gears feeding into the chamber external space a gas with a small amount of materials, which may form a carbon deposit. The invention also offers two versions of the method of realization of the catalytic cracking in a fluidized layer with utilization of the indicated reaction chamber. ^ EFFECT: the presented reaction chamber ensures an effective separation of the catalytic agent particles from the product of the diluted phase and feeding into the chamber external space a gas with a small amount of materials, which may form a carbon deposit. ^ 8 cl, 1 dwg |
