The filter in the photocatalysis reactor
The optical filter in the photocatalysis reactor played an important role in many aspects.
First of all, it could filter light and only allow light of a specific wavelength to pass through, thereby achieving fine control of the reaction light source, which helped to improve the specialization and efficiency of the biochemical reaction.
Secondly, different filter had different spectral transmissances, which could be used to control the light intensity and spectral distribution during the reaction process. This would not only help in the optimization of experimental conditions and increase the purity and yield of the product, but also help to reduce the occurrence of side reactions and reduce energy consumption and experimental costs.
In addition, the filter also had the function of protecting the photocatalysis reactor. Some light sources would generate high temperatures during long-term operation, which could cause the performance of the instrument to decline or even be damaged. The filter could effectively filter out excess light and reduce the heat of the light source, thereby extending the service life of the instrument.

byd reactor principle
In the BYD reactor, fresh and recycled formalin from the formalin plant entered the liquid phase of the BYD reactor, while the ethyne gas entered the bottom of the reactor and dispersed in the liquid-solid phase. Under the effect of the catalyst, the reaction occurred to form 1,4-butynegol (C2H2 + 2HHamster → HOCH2C = ccH20H (BYD)). After the pulp in the ByD reactor was filtered by the candle filter in the reactor, the filtered liquid entered the ByD collection tank (BD-V104). The reactor's internal components included a candle filter, an ethyne loop, a stirring device, a cooling coil, etc. The shell was made of Q345R + 316L.

Nuclear fission in the reactor
Take Uranium-235 as an example. When the nucleus of Uranium-235 was bombarded by external neutrons, one nucleus would absorb a neutron and split into two smaller nuclei, releasing two to three neutrons at the same time. The neutrons produced by the fission bombarded another Uranium-235 nucleus, causing new fission. If this continued, it would be a fission chain reaction, which would produce a large amount of heat.
In order to achieve such a nuclear fission reaction, the reasonable structure of the reactor should include nuclear fuel, moderator, heat carrier, control facilities, and protective devices. The nuclear fuel needed to be made from uranium ore through processes such as selection, crushing, acid soaking, and concentration to produce a certain amount of uranium and a certain geometric shape of the rod. In a traditional nuclear fission reactor, in order to improve the chain fission reaction efficiency of nuclear fuel, it was necessary to decelerate the high-speed neutrons (fast neutrons) produced by fission into slower neutrons (thermal neutrons). A neutron moderator composed of lighter nuclei (such as light water, heavy water, etc.) would be added to use the hydrogen atoms to decelerate the high-speed neutrons. The heat carrier could be used to take away heat to prevent the reactor from burning down due to overheating. The heat that was extracted could turn the water nuclear reactor into steam to drive the gas turbine to generate electricity. The control facility allowed the nuclear reactor to operate according to human wishes. The protective device was because uranium and fission products were highly radioactive and could cause harm to humans.
In addition to the traditional reactors that used Uranium-235 as nuclear fuel, there were also fast neutron reactors (nuclear fission reactors without neutron moderators) and thorium-based molten salt reactors (fourth-generation reactor nuclear energy systems that used thorium as nuclear fuel and composite fluorides as coolants). Their nuclear fission reaction principles were similar, but there were differences in specific fuel, efficiency, safety, and so on.

Is the cracking precipitator a reactor?
The FCCU consisted of a reactor (discharger), a regenerating, and other equipment. The discharger was a part of the reactor. It was not an overall concept of the reactor in a separate sense, but a component of the reactor that carried specific functions in the FCCU reaction system.

Inspection of stainless steel reactor
When accepting the stainless steel reactor, the following precautions should be taken:
1. ** Appearance **: Check the appearance of the reaction kettle to see if the surface is flat, if there are any scratches, rust, and other problems. At the same time, check if the welding line is uniform and free of cracks.
2. ** Data Review **: Review the design documents, manufacturing quality certification documents, installation and testing records of the reactor to ensure that the information is complete and accurate.
3. ** Performance test **: After adding a certain amount of materials, carry out the actual reaction operation and test the various performance indicators of the reactor, such as temperature control accuracy, stirring effect, material reaction effect, etc., to see if they meet the design requirements.
4. ** Safety inspection **: Check whether the safety protection devices of the reactor are complete and effective, and whether they meet the relevant safety standards and specifications.
5. ** Overall acceptance **: After the above inspections and tests are passed, the user unit, the installation unit, and the supervision unit will jointly sign the acceptance report to complete the acceptance work.
It should be noted that the specific acceptance process may vary depending on the model, specifications, and use environment of the reactor. In actual operation, it should be carried out strictly in accordance with the equipment manual and relevant standards.

Prehistoric civilization nuclear reactor
Traces of a nuclear reactor from two billion years ago were found at the Oklo mine in Africa. This discovery triggered many speculations about the prehistoric civilization.
Some people who supported the existence of prehistoric civilizations believed that nuclear reactors required a lot of manual operation to operate normally, such as enriching uranium- 235, controlling the reaction rate, adding neutron moderators, etc. Therefore, these nuclear reactors should have been built by a prehistoric civilization on ancient Earth.
However, scientists had fully explained it from the perspective of natural formation. Two billion years ago, the relative abundance of Uranium- 235 in the Oklo area could reach about 3.7%(its half-life was about 704 million years, and the concentration at that time reached the standard required for nuclear reactors). The area had a special geological structure. A specific layer of sand rock contained a large number of "thin sheets" rich in Uranium minerals, forming 16 nuclear reaction zones. There were a lot of tiny gaps and cracks in the area, and underground water could enter and exit. Groundwater acted as a neutron dimmer and a cooler. These conditions satisfied the operating mechanism of the nuclear reactor under natural processes. Moreover, scientists had found evidence of natural formation in their research, so they believed that this was the work of nature and had nothing to do with prehistoric civilization.

A child creates a nuclear reactor
There were two animations related to nuclear reactors. The protagonist of the Nuclear Energy Knowledge Challenge came into contact with different experimental methods during his journey to explore the discovery of atomic energy. The Nuclear Safety Challenge introduced the safe operation of nuclear reactors and accident prevention knowledge. The animation had a system to identify reactor problems and take emergency measures, but there was no mention of children building nuclear reactors. In addition, in reality, there were teenagers who were influenced by scientific magazine reports to build nuclear reactors. For example, Jackson Oswalt of the United States was influenced by the news that a 13-year-old child in the United Kingdom had successfully built a nuclear reactor. He wanted to build a reactor at the age of 12, and the materials were ready to be obtained from the Internet.
