The transformation of methanol to aromatics involves several key steps:
1. Methanol Activation: Methanol is initially converted to dimethyl ether (DME) through a dehydration reaction. 2. Olefins Formation: DME undergoes further dehydration and cracking to form light olefins such as ethylene and propylene. 3. Aromatization: The olefins undergo oligomerization, cyclization, and dehydrogenation to form aromatic hydrocarbons. 4. Hydrogen Transfer: Concurrent hydrogen transfer reactions help stabilize the aromatic compounds and prevent coking.
