Abstract
A process for converting a feed stream having carbon to Cto Colefins, 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 Cto Calkanes, transporting the mixture of Cto Calkanes to a second reaction zone, introducing a fresh stream of at least one of ethane and propane to the second reaction zone, converting the Cto Calkanes to Cto Colefins 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 Cto Colefins, and producing a recycle stream comprising hydrogen in the second reaction zone, where the recycle stream is transported to the first reaction zone.
