Aerosol Propellants & Refrigerants: High-purity DME effectively replaces Freon, reducing atmospheric pollution and ozone layer damage.
Chemical Production: Serves as a cost-effective raw material for formaldehyde production, particularly beneficial for large-scale operations.
Fuel Applications: Superior to LPG in storage, transportation, and combustion safety with better calorific value and combustion temperature.
Automotive Fuel: Ideal alternative energy source with excellent vapor pressure and octane number characteristics.
Methanol Dehydration Method: The predominant industrial method where methanol undergoes catalytic dehydration (γ-alumina, ion exchange resins) following the reaction: 2CH3OH → CH3OCH3 + H2O.
Synthesis Gas Method: Utilizes syngas (CO + H2 mixture) either through direct one-step conversion (2CO + 4H2 → CH3OCH3 + H2O) or two-step methanol intermediate process.
As global energy demands grow and environmental awareness increases, DME demonstrates rapid market growth potential. China's government-supported DME industry shows particular promise for future expansion across fuel and chemical applications.
Derived from coal resources, DME serves as a clean fuel alternative that burns without harmful emissions. With potential to replace 20% of gasoline consumption, it offers significant environmental and strategic advantages for sustainable development.
