Formaldehyde is widely used in many fields of industry. The increase in the need for formaldehyde led to an increase in scientific research, the purpose of which is to obtain the greatest yield of the product (formaldehyde) with minimal costs for raw materials, catalyst and its regeneration, energy carriers, etc. At industrial plants for the production of formaldehyde by oxidative dehydrogenation of methanol on the silver on pumice catalyst, the process temperature is maintained at 600 ° C. The process of obtaining formaldehyde by oxidation of methanol with air oxygen at the combination of catalysts "silver" and "silver on pumice" in the temperature range of 250–450 °C is investigated. The results showed the possibility of practical application of the combined catalyst. Chemical and technological parameters of the process with the use of a new catalyst are slightly lower than production indicators, however, the temperature of the pilot process is 2 times lower - this will reduce not only the energy costs, but also increase the life of the catalyst and the cost of its regeneration.
