Experts, I have an old question: which are the main manufacturers in China that produce formaldehyde using the iron-molybdenum method? Are Swedish Perstorp or Danish Topsoe technologies and catalysts being used? Which research institution in China can provide iron-molybdenum process technology and catalysts, and do they have any proven track record? Thank you so much!
There are many manufacturers in China that use the iron-molybdenum method for production; companies such as Yuntianhua, Chuan Tianhua, **Meike, and Shanxi Sanwei are probably unknown to you. There’s also the iron-molybdenum method for producing formaldehyde developed by the American company DBW.
Upstairs, people are asking about *production technology.
It seems that such technology does not yet exist in China. Besides Peerstorp and Topsoe from Denmark, there is also the FAMAX catalyst produced by Südchemie in Germany
Currently, there are no transfers of oxidation-based formaldehyde production facilities in China; Perstorp uses its own DBW catalyst, while CAL Company employs catalysts supplied by Southern Chemical. Of course, different companies’ processes can also make use of catalysts from other manufacturers. All the mentioned catalysts are imported; there is no production of iron-molybdenum catalysts in the country.
Zhejiang Ailide has introduced the formaldehyde production technology from Indian ALLIED (using catalysts from German Southern Chemicals), developed its own polymerization process, and it is operating well.
In China, most production still relies on the silver method. The iron-molybdenum method requires high initial investment in equipment, imposes strict requirements on fans, and consumes almost twice as much electricity as the silver method. Although its specific consumption is low, with lower alcohol content and acidity levels and better product quality, it is still preferable for new manufacturers to use the silver method, as this technology is already well-developed in China
The domestic production process for silver-based formaldehyde is already highly mature; the alcohol content can be kept below 0.5, while the acid content can be kept below 0.01. If necessary, we can provide equipment and technical support. Contact number: 13516396383
How is the DBW formaldehyde process in the United States? How is it performing in the domestic market?
I heard that the Southwest Research Institute in China has conducted research on this; it’s not entirely certain whether Sichuan Jinxiang has a domestic iron-molybdenum-formaldehyde production facility.
Topso’s catalysts are relatively expensive; we use those from Süddeutsche Unternehmen, and there are specialized departments in China that offer cheaper alternatives
