The invention consists in the installation in the lower ends of the chutes gas washers and locking grooves in the toroidal gas manifold, which is connected pipe flows from the nozzle of the reaction products. The device allows to increase efficiency and reduce capital and operating costs. 3 C.p. f-crystals,1 Il.

The invention relates to a device for carrying out catalytic processes, in particular for carrying out the process of catalytic reformirovania gasoline, and can be used in the petrochemical and refining industries.

Known reactor for carrying out catalytic processes, including the case with a spherical bottom, a protective shell, inside the shell Cup with a safety net, a Central perforated tube, a control grid, an input and an output fitting and the pipe unloading of the catalyst [1].

Aerogo distribution of raw materials at its radial flow.

The closest to the technical nature of the claimed reactor is a reactor for carrying out catalytic processes, containing a cylindrical housing within which is coaxially mounted a Central perforated pipe capped at one end and connected the other end to the pipe, perforated trough, positioned along the casing pipe of reaction products and unloading of the catalyst [2].

A disadvantage of the known reactor design is the complexity of the design and, respectively, arising from the relatively high operating costs.

The aim of the invention is the creation of the design of the reactor for carrying out catalytic processes that require less capital and operating costs, and more efficient by changing the volume of the catalyst.

This objective is achieved in that at the base of the chute is equipped with a gas washer and all chutes are closed in a gas toroidal manifold, in which tangentially installed pipe flows, connecting the collector connection of the output of raw materials.

To increase the rigidity Centralny flows to install thermocompensated.

To give constructive design flexibility pipe flows should be implemented in the form of flexible hoses.

The drawing shows a sketch of the proposed reactor for carrying out catalytic processes.

The reactor comprises a cylindrical housing 1 coaxially to the housing has a Central perforated pipe 2, connected at one end with the pipe 3, the input raw material, and the other end of the pipe 2 is plugged and relies on the socket 4 of the reaction products from the reactor. By forming the housing 1 a perforated trough 5. The upper ends of the chutes muted, and in the lower ends of the chutes equipped with a gas washer 6. All chutes 5 are closed at the base of the toroidal gas collector 7. From the bottom of the gas collector 7 tangentially withdrawn pipe flows 8 connected to the pipe 4 .The catalyst layer 9 fills all free space of the reactor. In the bottom of the reactor made pipe 10 for discharging catalyst.

The reactor operates as follows.

The flow of raw material is introduced into the reactor through pipe 3 and through the perforated Central pipe 2 is uniformly fed into the catalyst bed. The uniformity of movement of the layer of catalyst is ensured by setting rmes, after the layer of catalyst 9, enters the trough 5 and the washer 6 in the gas collector 7.In the gas reservoir 7 to the gas stream is given a rotational movement due to the tangentially installed pipe flows 8, resulting in stream flows 8 evenly introduced into the pipe 4 and is removed from the reactor.

Thus, in comparison with the known analogues, constructive design of the proposed reactor for carrying out catalytic processes is made easier. Namely, in the inventive design is not supporting the bottom, because instead of a toroidal gas manifold connected to the outlet of the reaction products pipe flows.

This design requires less capital, operating costs compared to the prototype.

In addition, the lack of a supporting plate allows you to increase the catalyst loading, and consequently, to increase the efficiency of the process as a whole, or to increase the productivity of the reactor.
