ABSTRACT:
In a process for oxidizing methanol to formaldehyde which comprises passing the methanol with molecular oxygen through two sequential silver-based catalysts, with the second of said catalysts being a bed of particulate silver such as, specifically, silver crystals, the process efficiency, and especially the efficiency of the reaction taking place in the second catalyst bed, is improved by controlling (a) the ratio of formaldehyde to methanol in the reactant gases entering the second catalyst bed and (b) the specific reaction rate in said second bed. The specific reaction rate is defined as the quantity of methanol converted in said second bed per unit time per unit of cross-sectional area of the bed.
