Description

The invention relates to methods for carrying out chemical-technological processes and can be used in chemical technology to intensify processes in heterogeneous systems, catalytic processes, catalyst regeneration processes.

The purpose of the invention is to simplify, expand technological capabilities and intensify the process by increasing and updating the surface of the interaction phase.

According to the method of carrying out chemical-technological processes. The final influence on the process by the electromagnetic field is directly

but the reaction medium is influenced by SO by impulses of eddy current, and the current pulses excite periodically

or depending on the value of the techno-QQ logic parameter, which changes j in the reaction medium, the eddy current is supplied in the form of damped or aperiodic oscillations with a period equal to or a multiple of the measurement period of the technological parameter in the reactor, and each subsequent pulse is excited in the first quarter of the period technological parameter change.

1 shows a device for driving pulsed vortex I currents in a reaction medium, longitudinal

incision; figure 2 - the same, with a rolled mash.

A device for carrying out chemical technological processes comprises a reactor 1, a reaction medium 2, a catalyst 3, a support ring 4 on which an inductor, an inductor 5, a current pulse generator b, a current generator start circuit 7, a primary converter 8 (sensor) of a process parameter, software switch 9, a highly conducting perforated gasket 10, a perforated casing of a group of inductors, periodic current pulses, a change in the process parameter in the reactor.

The method carried out in the operation of the device as follows.

Under the action of a signal from the primary converter (sensor) 8, a generator 6 of current pulses is started through the start circuit 7 and a current pulse passes through the inductor 5. According to the laws of electromagnetic induction in the reaction medium 2 or the catalyst layer 3 or in the gasket 10, a vortex pulsed current (Foucault currents) is induced. The rapidly varying pulsed eddy current in medium 2 (catalyst layer 3 or gasket 10) causes strong, rapidly changing magnetic fields of high tension. The interaction of the magnetic fields of the inductor and the eddy current of the medium (catalyst or gasket) will cause the effect of electromagnetic shock, repulsion. Under the action of impact in medium 2 or catalyst bed 3, a compressional (pressure) pulse wave arises, which propagates through the medium. The layer of medium or catalyst is injected, detached from the inductor, jumps, or the metal gasket 10 pushes up from the inductor, mixing either liquid reaction medium 2 or agitating catalyst 3.

If the catalyst bed 3 in the reactor 1 (Fig. 2) has a considerable thickness or is arranged in several layers, in layers, then the reactor 1 is supplied with several inductors 5 made as catalyst lattices and located in the catalyst bed 3 at a certain distance depending on, for example, from the power of the generator of current pulses or the conductive properties of the catalyst 3 or. reaction medium 2.

located in the reactor in layers, then each layer has its own inductor. Separate inductors are connected to the current pulse generator either directly in parallel or in series, or through software switch 9, which connects the inductors to the (pulse generator) in a certain sequence, creating, for example, a traveling wave shaking the catalyst from the bottom upwards through the catalyst bed, or vice versa.

It should be noted that the catalyst can be shaken in dry and wet versions, i.e. when the reactor is not filled with a liquid reaction medium or when it is filled with it. In the case when the catalyst bed is in a liquid, the IZHRT eddy current passes through either the catalyst bed or the fluid between the catalyst grains. The effect of shaking the catalyst occurs anyway. If there is a 10 IPM gasket, the catalyst shakes more in the dry and wet versions.

It should also be noted that if the catalyst in the reactor undergoes regeneration, then shaking the catalyst in any form, dry or wet, when the regenerating medium is a gas or liquid, leads to a significant reduction in the regeneration time, since when the catalazitor is shaken, the regenerating medium is faster and more efficient. will treat the entire surface of the catalyst, and loose deposits (pshak) will be carried away by the regenerating medium. When shaken, the regenerating medium will quickly restore the reactivity of the catalyst surface.

Possible with the proposed method and device is the complete regeneration of the catalyst without discharging it from the reactor. To enhance the cleaning effect and catalyst regeneration, it is better to use electrically conductive regenerating media.

Of particular note is the intensification of the process due to electromagnetic impact in the reaction medium or catalyst bed, catalyst shaking, increase in operating time and catalyst surface utilization ratio, increase in phase interaction surface, for example, in extraction processes, acceleration of catalyst regeneration processes, recovery of catalyst reactivity under the influence of pulsed magnetic field, increasing the chemical activity of the reacting substances under the action of magnetic th and electric fields. All this is achieved while at the same time simplifying the method and device, since there are no moving parts and elements with an external mechanical drive to implement the method, the electric and magnetic fields are created by a non-contact method.
