Sail across the sea

Chapter 55

"Out of the water! Out of the water!"

In the synthesis section of Canghai Chemical Fertilizer Factory, a group of cadres and engineers stared at the water outlet of the synthesis tower and shouted loudly.

"It's a miracle that the water started coming out just after 300 degrees!"

Meng Hai looked at the thermometer and clicked his tongue repeatedly.

After confirming the development of rare earth catalysts, under the auspices of Meng Hai, all the technical departments of Canghai Fertilizer Factory mobilized, moved out all the old documents in the reference room, screened one by one, and collected all the articles related to catalysts. picked out for comprehensive analysis.

To put it bluntly, these engineers and technicians in the technical department are indeed not all freelancers, and they still have at least the ability to analyze documents.

In the past few years, many units in China have been doing research on catalysts, and there are quite a few literatures in this regard.The role of rare earths in the catalysis of ammonia synthesis mentioned by Gao Fan has also been mentioned in several documents. Although it is not detailed, it at least proves that Gao Fan is not just making up based on imagination.

When everyone was looking through the literature, they found that there was no dust on the covers of these old magazines. After asking the data staff, they found out that Gao Fan had borrowed these magazines a month ago. He has touched the covers of magazines, which belong to the kind that can extract a few fingerprints.

In this way, there is an explanation for Gao Fan's monstrous behavior.Let me ask, who has read all the magazines in the reference room?They worked so hard, did you make it?

On the basis of analyzing the literature, the technical department finally came up with a detailed process design, including the ratio of various raw materials, melting temperature, cooling method, crushing method, final particle size, etc.These contents are all borrowed from the designs of other units, and it is not popular to talk about patent protection in this era. When many units write papers, they can’t wait to write all the details clearly, so that you are embarrassed. Learn from one or two.

Gao Fan originally wanted to participate in the entire design process, but Gao Yiping forced him to go back to school for class, and only allowed him to visit the technical department after school to see everyone's intermediate results.

In this way, it seems that Gao Fan is some kind of expert, and all the people in the technical department are helping him.

However, no one dared to express any dissatisfaction, because Gao Fan was indeed a bit of an expert.He did not analyze the literature with everyone, but when looking at the design proposals, he was able to put forward some unique suggestions every time, which made a group of gray-haired old engineers feel that their age had been spent on Dog.

At this point, all doubts about Gao Fan disappeared.You said that what he said before was taught by others. This kind of ability to pick out faults at a glance at the plan, who can teach him in advance?

If you dare to beep a few more times, Gao Fan can take out a pen and write an equation for you, and talk to you about how many kilojoules of heat released per mole, what is the third-order ionization potential, etc., with a cute face Ask you if he wrote it right.

Even if it's not right, I can't understand it!
This is the wail from the heart of several engineers.

Let me put it this way, in the past two days, the chances of being beaten at home by the children of Canghai Chemical Fertilizer Factory's technical department increased by 33.33%, because their father came back from get off work every day with a wave of evil spirits, and when he beat people, he repeatedly said last sentence:
Look at people!
People... who are they referring to, don't let me find out!

The children swear while clutching their swollen buttocks.

Gao Fan's proposal to engage in rare earth catalysts is purely a temporary idea.He heard from Gao Yiping that there was a problem with the catalyst, so he thought of making the catalyst himself.

In fact, it is not uncommon for fertilizer factories to make their own catalysts in this era.Chinese companies like to pursue "big and complete" and "small and complete". Canghai Chemical Fertilizer Factory has a very powerful machine repair workshop. If the general equipment fails, there is no need to go to the original manufacturer to buy parts. The machine repair workshop makes estimates by itself. It was created after a rough estimate.It is not surprising that some chemical fertilizer factories in China have nothing to do to build a catalyst workshop.

What Gao Fan wants to do, of course, is not to cobble together to produce a batch of catalysts, this matter is of little significance.He wants to use the technology he brought from later generations to help Canghai Chemical Fertilizer Factory develop a new product that is superior to the existing catalyst. At least he can win a scientific and technological progress award from the Provincial Chemical Industry Department, which can give his father some points.

When thinking of new products, he turned his mind and thought of the idea of ​​rare earth catalysts.In fact, some units are already developing rare earth catalysts nowadays, but the progress is still relatively slow.In later generations, rare earth catalysts are nothing new, and their advantages have also been recognized.

The advantage of developing rare earth catalysts is that the idea is simple, as long as cerium oxide is added to the original catalyst formula, it can have a certain effect.The optimal ratio can only be obtained through trial and error. The Canghai Chemical Fertilizer Factory does not have the ability and time to do so. Just a little improvement is enough.

The development of rare earth catalysts by Canghai Chemical Fertilizer Factory has more advantages than those domestic scientific research units, that is, the southeast of Maolin Province, where Cangtang County is located, is an important rare earth production area in the country, and there is a cerium oxide production enterprise in Cangtang County. The scale is small, and there is almost no sense of presence in the county.

But no matter how small the scale is, it is enough. Rare earth is called industrial monosodium glutamate, and it will work if you sprinkle a little in the product. Who has ever seen monosodium glutamate that needs to be eaten by catty by catty?
There is also a small iron and steel factory in Cangtang County, which is of course thanks to the construction of the "Five Local Small Industries" back then.The iron and steel plant is now in a half-stop state, and the fertilizer plant needs to use their electric furnace to smelt a furnace of ferric oxide, which is really not a troublesome matter.

The catalyst was produced, and it was crushed into small particles with a jaw crusher, which looked the same as the catalyst used in the fertilizer factory in the past.Gao Yiping personally directed the packing, installed about 0.3 cubic meters of catalyst in the synthesis tower, and then began to arrange the original start-up.

As mentioned earlier, the so-called original driving is to blow hydrogen and nitrogen mixture gas into the synthesis tower, and the hydrogen reacts with ferric oxide and iron oxide to reduce pure iron and water.The sign of the start of the reduction reaction is the effluent of the synthesis tower.The effect of the reduction is measured by the ratio of the actual water output to the theoretical water output. Generally, it must reach more than 95%, and it can be close to 99%, which is a very ideal state.

The reaction of hydrogen with ferric oxide and iron oxide requires a certain temperature.This temperature is generated by electric furnace heating, the higher the required temperature, the higher the power consumption.

Under normal circumstances, the temperature of the water at the beginning of the original driving should be around 350 degrees, and now the water starts to flow out just after 300 degrees, which shows that the reduction characteristics of the catalyst are better than the traditional catalyst.Based on this alone, Meng Hai knew that the technical department's efforts these days were not in vain.
