Regarding catalytic reactions: the translation of “a run”
Thread Content
The sample is analyzed to ensure that the reactor is carrying out the desired reactions. This sample indicates when the catalyst bed has become inactive to the extent that it is necessary to replace the catalyst. This sampling is required frequently throughout the operation of the reactor; by \"operation\" is meant the period from when a new catalyst is installed until that catalyst becomes ineffective, in other words, the catalyst replacement cycle. How should the last sentence be translated? During a single reaction batch, this sampling and analysis work needs to be carried out frequently. Another sentence: Low reactor conversion from start of the run. Original translation: The reactor conversion rate remained low once the reaction batch entered its initial phase.
SOR: Start of Run – the initial stage of the reactor operation; EOR: End of Run – the final stage of the reactor operation. Generally, at the beginning of the reaction, the catalyst has high activity, which leads to poor selectivity; therefore, lower conversion rates and lower temperatures are used. Towards the end of the reaction, the catalyst’s activity is lower, and selectivity tends to be better, so higher conversion rates and higher temperatures are required. Reactor Run generally refers to the cycle within a reactor in which the catalyst is used starting from the end of regeneration until it loses all activity and needs to be regenerated or replaced.
\"Run\" refers to operation; it has nothing to do with batches, right? Put simply: SOR means Start of Run, while EOR means End of Run
run---to execute SOR --Start of Run: the initial stage of execution; EOR ----End of Run: the final stage of execution (catalyst-related terms)
My suggestion for revision: This sample will be frequently required during a reactor run. The original translation was: This sampling and analysis need to be carried out frequently throughout a reaction batch. During the reaction, it is necessary to carry out this sampling and analysis work frequently. The next sentence describes a phenomenon assumed in the analysis of reactor failures: after replacing the catalyst, the reactor’s conversion rate is low, and possible reasons for this include the catalyst not being properly activated or having poor quality. Low reactor conversion from start of the run. The reactor conversion rate remained low from the beginning of the reaction batch. Change to: After replacing the catalyst, the reactor’s conversion rate is low.
during a reactor run (length) During one reactor operation cycle, the reactor conversion rate is low from the start of the run. In other words, the reactor’s conversion rate remains low right from the beginning of the operation.
This sample will be frequently required during a reactor run. I think it should be: samples need to be taken and analyzed frequently throughout a single reaction cycle to ensure that the catalyst has not become deactivated.
After rating echo, I thought carefully and realized that the translation was pretty much the same as mine. This sample will be frequently required during a reactor run. During a reactor’s operating cycle, this sampling and analysis need to be carried out frequently. This is better than my translation. Low reactor conversion from start of the run. The reactor’s conversion rate has been low since the operation began. Hasn’t it been just after replacing the catalyst since the operation started? Considering the context (catalyst troubleshooting), my translation seems more direct!
Let’s be more direct: lol :lol This sample will be frequently required during a reactor run. It will be used often while the reactor is in operation. Low reactor conversion from start of the run. Low reactor conversion rate after the operation began (after catalyst replacement). If the second sentence is in the paragraph and agrees with what was said above, it needs to be modified if it’s used as a title: lol :lol :lol
Low reactor conversion from the start of the run. Does “changing the catalyst” not mean “starting operation”? (For example, if you buy a piece of clothing, you can say “This piece of clothing suits you well,” but that doesn’t mean “It’s appropriate for you to buy this piece of clothing”). Can a literal translation explain why a different translation is needed? Furthermore, as you mentioned earlier, the low conversion rate is due to inadequate catalyst activation, resulting in activity that does not meet expectations, or it may be attributed to issues with the quality of the catalyst; therefore, the reactor’s conversion rate remains low from the start of operation (it is better to use “low” instead of “lower”). Or, how to phrase it better; let’s take a look again in context.
Also, I saw the comment on the 9th floor asking me to provide a translation of a sentence. I generally don’t provide sentence translations; “translation means conveying the meaning.” However, everyone has their own way of speaking, with different tones and styles, and the meaning of a sentence can be expressed in many ways. The saying “there is no perfect translator” is truly true!
The general meaning of the two translations is similar; they both address the issue of low conversion rates once the reactor starts operating. My suggestions are as follows: 1. If one doesn’t know much about the content or simply wants to provide a straightforward translation, then use \"after the reactor starts operating.\" 2. If one has a thorough understanding of the situation and knows that the low conversion rate is due to the recharging of the catalyst, then the translation \"as suggested by LU moderator\" can be used. 3. If this is a title and the reasons will be explained later, then option 1 should still be used; the reason cannot be stated directly. 4. Personally, I think LU moderator’s translation went a bit overboard, haha
This sample will be frequently required during a reactor run. Sampling needs to be done often throughout the course of a reactor operation. Low reactor conversion from start of the run. The reactor conversion rate is low after the operation begins.
Low reactor conversion from start of the run. There are currently two different but similar translations for this sentence: 1. The reactor conversion rate has been low since the start of the operation. 2 After replacing the catalyst, the reactor’s conversion rate is low. \"Start of the run\" here should refer to the first operation after the catalyst has been replaced, and it doesn’t just mean the beginning of the operation; there is a difference between these two translations. Assuming the catalyst lifespan is 1 month, if operation is stopped after half a month, half of the catalyst’s lifespan has already passed. Drive again after a week; at that point, in Chinese one could also say that operation has begun. But for the catalyst, it is already in the middle of its operating period. So, I think the second translation is more intuitive here. Also, I think it’s not quite appropriate to use an echo as a catalyst compared to buying clothes. “\"Replacing the catalyst\" is indeed not the same as \"starting operation\", but a low conversion rate can only be determined through sampling and analysis after operation. Therefore, the phrase “low reactor conversion rate after catalyst replacement” already implies operation. Wait until I put on my safety helmet, and then everyone can start throwing bricks. I’ll give everyone scores tonight; I need to get to work now.
First run – initial run; running it again after stopping it is called rerun. As the original poster said, it is only after running for a period of time after changing the reagent that one can know what the conversion rate will be. If it is necessary to convey the meaning of changing the dressing (and to be sure that it is after the dressing has been changed), adding parentheses will suffice. Low reactor conversion from start of the run. The reactor’s conversion rate has been low from the beginning of the operation (after catalyst replacement). Let’s add a few more words of justification: In a given context, the meaning of a sentence can generally be understood without much explanation. The poster should be pretty clear as to whether this sentence applies specifically after an emergency shutdown of the unit, during the first operation, or after catalyst regeneration. Everyone is here to discuss and deepen their understanding; just express whatever you think. There’s no need to be afraid of having different opinions. I believe everyone gets what they want from these discussions. It’s fine if someone chooses to translate “sample” as “test sample” – as long as there is enough context to understand that this sample is used for analysis in order to observe its performance.

Thank you all for your participation. I will still use the translation of “low reactor conversion rate after catalyst replacement”. Because this troubleshooting is primarily aimed at issues such as the catalyst not being properly activated and catalyst quality problems. If the reactor conversion is low after parking, the above two reasons can be disregarded.
