FIELD: chemical technologies; may be used in production of formaldehyde at enterprises of chemical, petrochemical and other industries. SUBSTANCE: method consists in supply to the reactor in several parallel flows of heat carrier with temperature of not less than 200 C. The main flow is passed through the first catalysts layer and successively through all the remaining layers of catalyst. Other flows are passed through any layer, except, for the first catalyst layer and then through all next catalyst layers. EFFECT: higher efficiency. 1 cl |
