| 摘要 |
Systems and processes for producing one or more olefins are provided. In one or more embodiments, a feed stream containing butane can be dehydrogenated to provide a first product containing butene. At least a portion of the first product can bypass an existing etherification reactor used for converting isobutylene to MTBE. At least a portion of the first product can be cracked using a catalytic cracker at conditions favoring the conversion of the first product to propylene to provide a second product containing propylene, ethylene, and butane. In one or more embodiments, a catalyst consisting of essentially a zeolite favoring the production of propylene can be used in the catalytic cracker. |
