Activation of Methanol: Methanol is first activated on the catalyst surface, where it undergoes dehydrogenation to form methoxy species. Formation of Hydrocarbons: The methoxy species further undergo various reactions such as oligomerization, cyclization, and hydrogen transfer to form a mixture of hydrocarbons. Product Separation: The resulting hydrocarbons are then separated and purified to obtain the desired products, such as propylene, ethylene, and gasoline-range hydrocarbons.
