Industrially, formaldehyde is produced by catalytic oxidation of methanol. The most commonly used catalysts are silver metal or a mixture of an iron oxide with molybdenum. In the recently, most plants are using Formox process with iron oxide and molybdenum as catalyst, the methanol and oxygen react at 300-400°C to produce formaldehyde according to the chemical equation:
CH3OH + ½ O2 → H2CO + H2O.
Dimethyl ether (DME) is being recognized as a clean alternative fuel because of the increasing energy demand. The simplest ether, it is a colorless gas that is a useful precursor to other organic compounds and an aerosol propellant that is currently being demonstrated for use in a variety of fuel applications. It is an isomer of ethanol. Catalyst design is at the heart of enhancing the catalytic efficiency of DME synthesi. Dimethyl ether synthesis catalyst.
Chempack offer the iron oxide and molybdenum(Fe-Mo) Catalyst with high activity, selectivity and stability.
Chempack DME synthesis catalyst is an alumina based dimethyl ether synthesis catalyst for dehydration of methanol. It is resistant against by-products such as trimethylamine (TMA) in the methanol feed.
