DME is already an important basic chemical today. DME plays a key role as an intermediate product in the large-scale methanol-to-chemicals and methanol-to-fuels processes. Olefin synthesis is the decisive process step in the production of fuels such as sustainable aviation fuels (SAF/kerosene), diesel and gasoline from methanol or DME. Compared to methanol, DME offers numerous advantages in terms of catalyst stability, reaction speed and selectivity. It has been shown that the DME-to-olefin reaction enables higher olefin yields than the comparable methanol-to-olefins process. At the same time, the use of DME is associated with reduced exothermicity and lower water requirements for the reaction medium. Both have a beneficial effect on catalyst life. All in all, this results in great potential for producing fuels and chemicals based on DME more efficiently, with lower CO2 emissions and at lower costs.
