Despite its advantages, the MTO process faces several challenges:
Coking: The formation of carbonaceous deposits on the catalyst surface can deactivate the catalyst over time, reducing its effectiveness. Selectivity: Achieving high selectivity for desired olefins while minimizing the formation of undesired by-products is challenging. Process Optimization: Optimizing reaction conditions such as temperature, pressure, and methanol feed rate to maximize olefin yield is complex.
