"I saw a document saying that the Pujiang Chemical Industry Research Institute tried adding cerium oxide to the catalyst in the 1950s and found that the activity of the catalyst was better than that of traditional catalysts. However, it was not suitable for industrial applications because of its poor strength.
It can be promoted. Have any of your uncles and aunts heard of this?"
Gao Fan asked the engineers in the technical department.
Everyone was at a loss. This knowledge point was a bit too unknown, and no one had ever heard of it.
Gao Fan nodded with satisfaction and continued: "In the past 20 years, there has been a lot of research on the catalytic effect of rare earths abroad, but they are mainly used for petroleum cracking and automobile exhaust treatment. The use of rare earths in ammonia synthesis catalysts is rare."
"I know this." Wu Zequn spoke quickly. If he didn't speak, he would be despised by this little kid. "The catalytic effect of rare earths is mainly because rare earths have a paramagnetic structure, which has a relatively large impact on the hydrogen conversion reaction.
Influence, in addition..."
"Uncle Wu is right." Gao Fan affirmed and interrupted Wu Zequn's eloquence.
Wu Zequn had a proud smile on his face, but his smile froze immediately.
Damn, I’m so proud of myself. A little kid praised me and I’m actually proud of myself!
"Some foreign studies have shown that various rare earth elements have good catalytic effects. A few years ago, a company in Switzerland developed a spherical ammonia synthesis catalyst containing 0.5% cerium. It is said to have good low-temperature activity, but because the cost is too high
It’s big and has not been promoted,” Gao Fan said.
"You mean, you think we can give it a try?" Meng Hai understood the meaning of Gao Fan's words.
Gao Fan just said that he has a new plan, and then he talked about the role of rare earths. Doesn't this mean he wants to try to develop a rare earth catalyst? Meng Hai couldn't think of any benefits of rare earth catalysts at the moment, but everyone in the chemical industry has them.
Such a habit is to throw some other elements into the product when nothing happens, and sometimes a surprise will come out.
The traditional catalysts are nothing more than ferric oxide, aluminum oxide, potassium oxide and calcium oxide. If you throw some cerium oxide into it, there seems to be no problem. Gao Fan said that some people have done this abroad, which shows that this method is
It's feasible, at least it won't be worse than the current situation.
Then try it.
"Xiaofan, is this the suggestion you want to make?" Wu Zequn spoke up, "Is your basis based on seeing foreigners do this?"
"Of course not." Gao Fan said, "Foreign practices just gave me an inspiration. I have thought about this issue specifically and believe that adding cerium to iron-based catalysts should be beneficial.
"First, the effect of cerium oxide is similar to that of potassium oxide, both of which can improve the activity of the catalyst. However, cerium will exist on the catalyst surface longer than potassium, which can extend the service life of the catalyst and reduce the frequency of catalyst replacement.
"Second, Uncle Wu just mentioned that rare earth elements have a special magnetic structure, which can effectively improve the low-temperature activity of the catalyst. Reports show that after incorporating rare earth elements, the reduction temperature of the catalyst can be reduced by more than 40 degrees Celsius, which helps
Shorten driving time and save driving energy consumption.
"Third, cerium reacts more reactively with chlorine and sulfur than iron. If the feed gas contains hydrogen sulfide, it will first react with cerium to form sulfide, thus avoiding sulfur poisoning of the catalyst. Moreover, rare earth sulfide
The chemical also has catalytic activity, which makes the catalyst more resistant to toxicity."
Everyone was dumbfounded.
What you said makes sense, and we can't find a reason to refute it. What is the catalytic activity of rare earth sulfides? This knowledge is beyond the scope. I have never heard that an engineer at a small nitrogen fertilizer plant in a county needs to learn this knowledge.
.
Someone peeked at Gao Yiping and found that Gao Yiping's eyes were also filled with horror. This was really something that could not be faked.
It is true that Gao Yiping is a college student, but when he later became a leader, his professional skills have long been abandoned. When it comes to issues such as production processes, Gao Yiping can indeed be regarded as a professional cadre, but when it comes to how the catalyst works, he
It's definitely not working.
Even those in the technical department who are professional in technology can barely understand that this problem is related to principles such as atomic structure and electronic transition. If they were asked to explain it clearly, they would not be able to do it.
Gao Fan said everything that no one could do, which shows that his knowledge definitely did not come from the factory. Gao Yiping couldn't teach him, and Zhou Xiaoyun probably couldn't teach him either. Zhou Xiaoyun is indeed very good, but she
If you are not a catalyst, how can you understand this cutting-edge knowledge?
I heard from the children at home that word spread in Cangtang No. 1 Middle School that Gao Fan had special powers and was certified by the Provincial Science and Technology Commission, and that he could carry a fork with a certificate.
I didn’t believe it in the past, but now it seems that what I was told was true.
"Lao Meng, do you think Gao Fan is right?"
Gao Yiping happily followed his son out to refill everyone's guns. He didn't understand even 30% of what his son said, but he could understand the expressions on everyone's faces, just five words: envy, jealousy, and hate.
I let you speak ill of my son behind his back!
I ask you to write anonymous letters!
I make you jealous!
Don’t even look at whose baby this is!
Do you think my baby’s name is Gao Fan? Do you really think he is ordinary? Let me tell you, on the day I gave birth to Gao Fan, I dreamed of an old man with a white beard who told me that my future future is limitless and I must choose a low profile.
I named him Gao Fan.
You know nothing!
Seeing Gao Yiping's gloating expression, Meng Hai sighed inwardly, squeezed out a smile on his face, and said:
"I think Gao Fan spoke very comprehensively. Many people are studying rare earths now. Some people call it industrial monosodium glutamate. I think we can make a furnace of catalysts ourselves and add a little of this monosodium glutamate to try the taste.
Okay.
"If it is done, our factory will launch another satellite. Rare earth catalysts are something that even foreigners have not done. If we do it, it is called glory for the country. Let's talk about it.
no?"
Could it be otherwise?
If you think it’s not the case, why don’t you go ahead and explain a lot of reasons.
Everyone thought that they didn't have the same opinions as Gao Fan, so they could only agree, and they all expressed their opinions hurriedly:
"Yes, you can definitely give it a try!"
"It doesn't matter if you try it. How much will it cost?"
"What Gao Fan proposed, can it be wrong?"
"Tsk tsk, Director Gao, how did you train Gao Fan? Please pass on your experience whenever possible. That child of mine..."
"This has nothing to do with training. The main thing is that the ancestral graves of Director Gao's family were buried well..."
