I want to know which one, formaldehyde or the products derived from formaldehyde, has the best performance or the most advanced technology. Thank you

Reply to 1#: It has no temper. Currently, the main methods for producing formaldehyde are the iron-molybdenum method and electrolytic silver oxidation; in China, the electrolytic silver oxidation method is mostly used. The processes and equipment required for this method are available everywhere. Its main advantages are low investment costs and low production capacity, but it involves high consumption of methanol. Abroad, companies such as Porstorp AB in Sweden, D.B.W in the United States, and DuPont use the iron-molybdenum process. Compared to other methods, this process allows for a higher production capacity (up to 15 Wt/year per unit), along with a higher methanol conversion rate; the methanol consumption is around 0.430. The catalyst needs to be replaced only once every year or so, and there is significant amounts of steam generated as a by-product. However, the investment required for equipment using this process is high, the cost of catalysts is elevated, and electricity consumption is also high. If the company has strong capabilities, for the iron-molybdenum method it is recommended to use products from Sweden or DBW in the United States; there are also manufacturers in China, and their production is generally stable. If you want to know more details, feel free to contact me; I might be able to provide some guidance for you.
