my country's formaldehyde industry has also experienced a relatively long development process. As a professional formaldehyde manufacturer, Quanxing Chemical will take you to understand it.
In the 1950s, my country's formaldehyde industry started in Shanghai Solvent Factory. The technology used at that time came from the Soviet Union. Pumice silver was used as a catalyst. The system pressure was lower than normal pressure, and the oxidation temperature was between 650 and 750 degrees Celsius. Then the formaldehyde passed through After the water is diluted, it enters the evaporator to evaporate. After such a production process, formaldehyde is produced. With the continuous development of science and technology, in the mid-1960s, there was a higher requirement for the concentration of formaldehyde, and iron molybdenum oxide catalysts were already used in the production process of formaldehyde at this time. By 1997, my country had developed a new generation of formaldehyde catalyst, electrolytic silver. The successful development of this catalyst gave my country a new development space for the formaldehyde industry. In the 21st century, major formaldehyde manufacturers have gradually increased the production capacity of oxidation reactors, and made continuous innovations and breakthroughs, which put forward higher requirements for various properties of catalysts.
