Hydrogenation reactors are widely used in various catalytic reactions, high-temperature and high-pressure synthesis, hydrogenation reactions, gas-liquid two-phase, liquid-liquid two-phase, exothermic reactions, composition testing, stability, corrosion testing, fine processing, supercritical reactions, catalyst evaluation, and other chemical reaction applications. We need to be cautious and standardized when using and storing in order to improve safety and its lifespan. The following are several suggestions for the main requirements of hydrogenation reactors for your reference.
1. Generally, industrial hydrogenation reactors need to withstand a certain pressure, with typical operating conditions below 10MPa. To carry out hydrogenation, pressure is usually required.
2. If you are conducting a small-scale hydrogenation reaction, you can consider using a pressure resistant HoTong instrument stainless steel kettle hydrogenation reactor. If the material of the stainless steel kettle has an impact on the catalytic effect of the catalyst, it is recommended that you line the kettle with a PTFE inner liner. When conducting small-scale/pilot tests, the displaced hydrogen gas can be introduced into a water tank. Generally, chemical plants have water tanks, and it is important to ensure that they are clean water tanks. When releasing hydrogen gas, it should be slowly released, and after release, it should be pumped out and replaced with nitrogen gas.
3. If the catalyst is palladium carbon, it is not easy to catch fire when placed in a damp place. When adding to the hydrogenation reactor, add quickly and then add the solution used for the reaction, do not wait.
4. After the hydrogenation reactor reaction is completed, remember to cool it down before discharging, then discharge hydrogen gas, fill nitrogen gas for exhaust, and then filter press to recover the remaining catalyst. If hot pumping is required, the hydrogen must be completely discharged before pressure filtration. Catalysts can be washed with solvents and sealed for storage.
5. Generally, the catalyst used in the pilot test will be used until its activity is exhausted, and it is rarely removed after one attempt. Only when it fails and needs to be reactivated, will the catalyst be removed, so there is no need to worry too much about the danger of the catalyst.
6. Before hydrogenation, it is necessary to check the sealing of the device and carefully inspect every detail, such as valve switches and safety valves, to ensure that they do not leak air or liquid. Also, check the pressure gauge and thermometer on the kettle. If there are any abnormalities, they must be corrected. Once everything is ready, the reaction can proceed.
