Catalytic production of olefins at high methanol partial pressures |
| abstract |
Disclosed is a catalytic method for operating an oxygenate to olefins conversion reaction to provide a substantial quantity of prime olefin in the product. The product is provided by operating within desired parameters of weight hourly space velocity and oxygenate partial pressure. Operating the reaction to supply oxygenate at an oxygenate proportion index of at least 0.5, and controlling weight hourly space velocity and molar flow rate of oxygenate to the reactor to maintain a partial pressure-velocity compensation factor of at least 0.1 psia<-1>hr<-1>, a prime olefin selectivity of at least 45 wt. % can be maintained. |
