Methanol is a major chemical building block used to manufacture formaldehyde, MTBE, acetic acid and a wide range of other chemical products. The slowdown in MTBE demand, mainly due to the decision taken by California and later by other states in the US to eliminate its use in the gasoline, is causing some of the producers in the world to explore alternate utilization of their existing methanol plants. One such utilization is the conversion of methanol to olefins (MTO). The production of light olefins from methanol was first realized around 1977, during the development of Mobil's methanol to ga...
Methanol is a major chemical building block used to manufacture formaldehyde, MTBE, acetic acid and a wide range of other chemical products. The slowdown in MTBE demand, mainly due to the decision taken by California and later by other states in the US to eliminate its use in the gasoline, is causing some of the producers in the world to explore alternate utilization of their existing methanol plants. One such utilization is the conversion of methanol to olefins (MTO). The production of light olefins from methanol was first realized around 1977, during the development of Mobil's methanol to gasoline (MTG) process. In the MTG process, where ZSM-5 is used as a catalyst, methanol is first dehydrated to dimethyl ether (DME). The equilibrium mixture of methanol, DME and water is then converted to light olefins. Here in this research we study catalytic conversion of MTO, mainly SAPO-34 and ZSM-5, synthesized, properties, applications.
