Inquiries about coupling alcohol catalysts
Thread Content
Is there any company that buys co-alcohol catalysts recently? What is the price? Nanhua Research Institute, Nanhua Catalyst Factory, Changshu Kaifeng, Changzhou Jinzhou, etc.
Nanhua Catalyst Factory has now switched to BASF catalyst. I heard the price is almost 60,000. This post was last edited by dragon.kong on 2008-2-21 09:57 ]
Our unit uses catalysts from Nanhua Institute of Chemical Technology, which has been changed to BASF. The new price now is around 59,000, which has increased a lot. Is copper also rising? I heard that the supply is still tight. Hubei Shuangjian's and Linqu Daxiang's are also good. This post was last edited by sdtzwh on 2008-2-20 16:49 ]
Nanhua Research Institute, Nanhua Catalyst Factory seems to be no longer connected, it looks like more than 70,000 to 81,000 cubic meters, with a heap specific gravity of about 1.5, Changshu Kaifeng, Changzhou Jinzhou Linqu Daxiang price killer. The price is lower than ours, and Shandong has a large market share. Sichuan Yalian's more than 60,000 is closer to 70,000 points per cubic meter, and the heap ratio is relatively low, about 1:4. Gaga, I am from Sichuan Asian League. Alas, the current joint alcohol catalyst production has no technical content at all, and they are all competing for price. I think technical services are also something that needs to be valued. The price is closely related to the price of metallic copper, and catalyst prices can fluctuate by several thousand per cubic meter within a month.
Haha, there is something wrong with Sichuan Asian League. . . I just asked a few days ago and it cost more than 76,000 cubic meters. But Linqu Daxiang is indeed very cheap, quack, I don’t even know if they are made of copper.
I don’t dare to buy cheap things these days! I’m afraid of fakes! Things are better from foreign BASF!
Each factory has its own processing technology, some of which use nitric acid nitrification of copper plates (represented by Nanhua)； Some are made with copper ions (ammonia is used), and its requirements on raw materials are not as demanding as the previous methods.
I would like to ask the person above why the catalyst produced by the ammonia complex method does not have high requirements for copper? I would like to know. As far as I know, the raw material used for the copper-zinc low-temperature shift catalyst produced by the ammonia complex method is also electrolytic copper, and ordinary copper is not used (Liaohe's B205 and Nanhua's B206 are like this).

Haha, I can't cheat, it's impossible not to use copper... But you have to pay attention to cutting corners and cutting corners, and you have to strictly control it when purchasing...
Our company has two combined alcohol towers, 1200mm and 1400mm. The copper-based catalyst of 1200 is stable in use, while the 1400 needs to be replaced in less than a year. In the past few days, the specific reason is said to be that the design of the synthesis tower of 1400 is defective. This is the case in several factories. The 1600 is similar to the 1200, and the catalyst has a long service life!
Nanhua Research Institute, model: C207. A new 1400mm was installed this month. Now the catalyst hot spot is almost six o'clock. The boss is very angry. According to analysis, it is related to the tower structure. The same is true for brother manufacturers. The 1200 has been running well for several years, and the 1600 is also.
