Is a rise in reactor temperature more harmful to the reactor or to the catalyst?
Thread Content
Personally, I think it poses a serious threat to the reactor; while the catalyst may simply lose its activity due to being exposed to high temperatures, the reactor itself could get deformed.
It not only poses a serious threat to the reactor but also creates a significant risk to production, potentially leading to failures such as explosions
The main issue is the significant harm caused by the catalyst, which leads to its deactivation and a reduction in its strength. Reactors generally have linings, and as long as there is no prolonged severe overheating, it usually does not cause damage to the reactor.
Excessive temperature in the reactor not only causes the catalyst to lose its activity or even burn out, but in severe cases without any protective measures, an explosion may occur.
If the reactor temperature rises excessively, it will first cause damage to the catalyst. If the temperature continues to rise, it will also cause harm to the reactor. Therefore, in terms of the degree of harm, once excessive temperature rises cause problems in the reactor, the catalyst is essentially rendered unusable. From this perspective, it should have a greater impact on the catalyst.
Agree with what was said above. First and foremost, it is the catalyst that gets damaged; high temperatures can cause sintering of the catalyst, resulting in a decrease or even loss of its activity. If the side reaction is a highly exothermic one, failure to control it promptly can lead to an increase in temperature, further damaging the reactor.
It’s of course a catalyst. Generally, catalysts are very sensitive to temperature, and reactors usually have a certain temperature range they can tolerate. It is essential to remove heat from the reactor in a timely manner; otherwise, the consequences of heat accumulation could be disastrous
It poses a serious threat to the reactor and also creates a significant risk to production
Excessive reactor temperature first causes hydrothermal deactivation and high-temperature sintering of the catalyst, leading to a decrease in its activity. At the same time, high temperatures can cause damage to the internal components of the reactor.
Hehe, when the reactor’s temperature soars, there’s no time to worry about whether it’s the catalyst or the reactor – the top priority is to get the temperature down! Down! Down! Have you seen the temperature exceed the limit? Not to mention catalysts, it’s normal for the internal components of the reactor and the measuring elements to get damaged as well. It’s difficult to answer LZ’s question; the problem mainly lies with the catalyst, which is obvious. As for problems with the reactor, they can be attributed to various other factors. Even if there are minor issues, it’s necessary to keep using it rather than discarding it.
Equipment damage is secondary; what’s crucial are the potential safety issues and the decrease in catalyst activity
The damage caused to the reactor is severe. Modern catalysts are designed to be heat-resistant, so extreme temperatures do not destroy their structure; however, they can cause serious damage to the reactor, such as the peeling off of the cladding layer and leaks in the reactor’s outlet flanges. If not controlled properly, fires and explosions can occur. In my opinion, when extreme temperatures occur, it is essential to ensure that the equipment does not suffer serious damage, and the process should be managed in a gradual manner, taking into full account the impact on the equipment
If over-temperature occurs, the main focus is on ensuring the safety of the device. Some major equipment requires a parking fee to be protected. In most cases, it is necessary to reduce the amount of CAT/raw material and increase the amount of CWS in order to lower the R temperature.
