What are the benefits of uniform velocity within the reactor?

If the speed is uniform, the product quality can be better guaranteed, and secondly, it is also beneficial to his service life.

If the velocity is uneven, the reaction will be uneven, so the result of the reaction will be more delicate.

Uniform, and the reactor water level can be controlled. The light source part is composed of ultraviolet lamp and quartz casing, and the immersion columnar light source fixed by the reactor cover plate is uniformly arranged along the direction of water flow, and the light source utilization rate is high, and the light intensity can be.

This is the problem of the relationship between speed and uniformity, that is to say, the two are proportional, the faster the speed, the smoother the flow of the production line, and the smoother it is not easy to form a breakpoint, then the result is of course high uniformity.

The biggest advantage of the uniform speed in the reactor is that it can achieve the ideal effect in a more rhythmic manner, so that its operation can be regularized and can give full play to the greatest advantages.

In general, the reaction speed depends on the reaction temperature, usually to increase the catalyst circulation capacity, increase the agent-to-oil ratio to achieve the purpose of increasing the reaction temperature and increasing the reaction speed. However, this will also lead to too much oil in the catalyst, and the more heat will be generated during the scorching process of the catalyst entering the regenerator, the higher the temperature of the regenerator. Therefore, the increased reaction speed of the riser will lead to an increase in the regeneration temperature in the regenerator.

What are the benefits of uniform velocity within the reactor? I think the speed in the reactor has improved evenly, which is a lot, and the speed of this sample is more uniform.

The benefit of uniform speed in the reactor, I think it should be possible to give the impression that it is relatively stable.

Inside the reactor. It's good to be dizzy. If there is, if the input in the reactor is good, it means that it is with you and the quality is very good, the workmanship is normal, if it is not good, I will say that you are a second-hand product, or a pirate.

In general, it is as close as possible to use less electricity and be more efficient.

During the reaction period, the speed is uniform, and the benefit of uniformity is that the speed in the reactor is uniform, and the advantage is that it is very regular.

I feel that the speed is not good to drink, this should be on the check-check network, it is directly more healthy and balanced.

The benefit of uniform speed in the reaction reactor is that the operation is very smooth.

The benefit of the average velocity in the reactor, this should be that they are more careful about this matter, but I don't know much, so if you want to give it to grandpa, you can only ask yourself.

The speed of Yin Qi, the words of the barracks must be beneficial, it can be used better, right?

Brother still has a lot of benefits, because he is relatively even?

The advantage of uniform speed during the reaction period is that it must be uniform.

When the reaction material flows in a reactor with a large aspect ratio, the fluid in each microelement volume in the reactor is at the same velocity.

The degree moves forward, and this flow form is called flat push flow;

Due to the strong stirring effect of the reactor, the micro-elements of the materials that have just entered the reactor and the original materials in the reactor are instantaneously fully mixed.

Together, so that the concentration of each point is equal and does not change with time, and the outlet fluid composition is equal to the inside of the device, and this flow form is called ideal mixed flow.

One isStayTime, one isAverage stayTime.

In the intermittent reaction, the materials involved in the reaction are discharged after all the reactions are completed in the container. All materials must be identical in the reactorStayTime.

In the continuous reaction, the materials involved in the reaction are discharged while entering the container. Theoretically, there are materials that go in and come out immediately and materials that do not come out for a long time, so they can only be measuredAverage staytime.

In general, the average residence time of continuous reactor material is shorter than that of batch reactor material.

The continuous reactor is simple to operate, the process is stable, and the quality of the products produced is stable between batches. The reaction of the batch reactor is difficult to control, and the process stability is relatively poor, but the batch reactor is very beneficial to the chemical reaction that requires a very complete reaction, and the reaction time can be extended to ensure that the material reaction is complete.

In an ideal continuous reactor, the concentration of the reaction is equal to the concentration at the outlet, so the continuous reactor is a low concentration reactor.

In the positive series reaction, the reaction speed decreases with the decrease of concentration, and the average residence time of the continuous reactor is longer than that of the batch reactor to achieve the same degree of reaction.

In the image of residence time, the residence time of an ideal batch reactor is a value.

The residence time of the continuous reactor material is a distribution curve similar to a normal distribution.

The catalyst is homogeneous and consistent.

In order to ensure that the reaction rate is consistent.

1. Classified according to the phase of the material.

According to the phase state of the reaction mixture in the reactor, the reactor is divided into two categories: homogeneous and heterogeneous reactors. The homogeneous reactor is a reaction material that is uniformly mixed or dissolved into a single gas phase or liquid phase, which is divided into a gas phase reactor and a liquid phase reactor. Heterogeneous reactors are divided into gas-liquid phase, gas-solid phase, liquid-liquid phase, liquid-solid phase and gas-liquid-solid phase.

2. Classification according to the structure of the reactor.

According to the characteristics of the reactor structure, it can be divided into reactors such as kettle type, tubular type, tower type, fixed bed and fluidized bed.

3. Classification according to operation methods.

The reactor is classified according to the operation method, which can be divided into three types: batch type, semi-continuous type and continuous type.

4. Classification according to temperature conditions and heat transfer methods.

The reactor can be divided into isothermal and non-isothermal according to the temperature conditions. According to the heat transfer method, it can be divided into adiabatic type, external heating type and natural type.

Multi-stage reaction, with a sieve hole added between each fraction.

It can only be that the pre-reaction ratio is reasonable, and the problem of more adequate reaction has not been solved at present.

Classification of ideal reactors: 1. Batch reactor 2. Horizontal flow reactor 3. Full mixed-flow reactor.

As for the volume discussion, there are many aspects to consider, such as residence time, reaction empty time, reaction volume, etc., which can not be summarized in one or two sentences. You're doing school homework, right? Landlord...

What reactions can occur with a homogeneous frontal phase reactor?

Also known as filling the bedbed reactor, it is a reactor filled with solid catalysts or solid reactants to achieve a multi-faceted reaction process. The solid matter is usually in the form of granules, with a particle size of about 2 15mm, and is stacked into a bed of a certain height (or thickness). The bed is stationary and the fluid reacts through the bed.
