摘要：
A process for converting a feed stream having carbon to C 2 to C 5 olefins, includes introducing a feed stream including methane and oxygen to a first reaction zone, reacting the methane and oxygen in the first reaction zone to form a first reaction zone product stream having a mixture of C 2 to C 5 alkanes, transporting the mixture of C 2 to C 5 alkanes to a second reaction zone, introducing a fresh stream of at least one of ethane and propane to the second reaction zone, converting the C 2 to C 5 alkanes to C 2 to C 5 olefins in the second reaction zone, producing one or more product streams in the second reaction zone, where a sum of the one or more product streams includes C 2 to C 5 olefins, and producing a recycle stream comprising hydrogen in the second reaction zone, where the recycle stream is transported to the first reaction zone.
