| titleOfInvention | Selective conversion of oxygenates to propylene using mobile bed technology and hydrothermally stabilized bifunctional catalyst system |
| abstract | The average propylene cycle selectivity of the oxygenate to propylene (OTP) process using a bifunctional oxygenate conversion catalyst is characterized by (1) mobile phase reactor technology in the hydrocarbon synthesis portion of the OTP flow process, replacing the prior art fixed bed technology; (2) a hydrothermally stabilized bifunctional catalyst system containing molecular sieves dispersed in a phosphorus modified alumina matrix that retains bifunctional capability and contains labile phosphorus and / or aluminum anions; And (3) a combination of up to 400 hours of catalyst on-stream cycle time. These conditions stabilize the catalyst against hydrothermal inactivation and maintain the accumulation of coke deposits on the catalyst to a degree that does not substantially reduce bifunctional catalytic activity, oxygenate conversion and propylene selectivity, thereby substantially cycle initiating average propylene cycle yields. Level or close thereto. |
