Formaldehyde synthesis Catalyst – SARV320

SARV-320 is a ringed shape mixed oxide catalyst with a pale-green color developed for high-selective oxidation of methanol to formaldehyde. SARV-320 is a highly competitive catalyst that significantly enhances the production capacity of formaldehyde per mass of catalyst with a long lifetime.

Process:
Formaldehyde is a key intermediate in the petrochemical industry to produce some complex materials including urea-formaldehyde resins, melamine resins, and phenol-formaldehyde resins.
Formaldehyde is industrially synthesized by catalytic oxidation of methanol over silver or iron-molybdenum metal-oxides. The latter, Fe-Mo mixed oxide, consists of up to 75% molybdenum oxide and 25% iron oxide. In the presence of about 10% methanol mixed with air at 250–380°C at the pressure of 1 barg, the reaction takes place and the main products are formaldehyde and water. The main factor in this reaction is to selectively direct the reaction toward formaldehyde production path and prevent the conversion of methanol to CO₂, dimethyl-ether or formic acid.
