HIGH PRESSURE SWING FIXED-BED PROCESS WITH OPTIONAL ETHYLENE RECYCLE FOR HIGHLY SELECTIVE METHANOL TO OLEFINS CONVERSION |
| 摘要 |
A process is presented for the production of light olefins. The process utilizes a SAPO-18 catalyst and is operated at an elevated pressure. The process generates higher concentrations of heavier olefins which can then be processed to generate light olefins. The processing of the heavier olefins can include metathesis reactions and olefin cracking processes. |

1. A process for the production of light olefins from an oxygenate feed, comprising: passing the oxygenate feed to an MTO reactor, wherein the reactor comprises an MTO catalyst comprising a silicoaluminophosphate, and is operated at reaction conditions to generate suitably stabile conversion for extended run lengths. |
