DME can be produced through several catalytic methods:
Methanol Dehydration: This is the most common method, where methanol is dehydrated over an acidic catalyst such as alumina or zeolites. Direct Synthesis from Syngas: In this process, syngas (a mixture of CO and H2) is converted to DME using bifunctional catalysts that combine methanol synthesis and methanol dehydration functions. Biomass Gasification: Biomass is gasified to produce syngas, which is then converted to DME.
