1. A method for converting a lower alkane to an alkene comprising:
providing an input stream comprising oxygen and the lower alkane to an oxidative dehydrogenation (ODH) reactor;
converting at least a portion of the lower alkane to the alkene in the ODH reactor and producing an ODH outlet stream comprising the alkene, an oxygenate, water, and carbon monoxide;
providing at least a portion of the ODH outlet stream to a water gas shift/hydrogenation (WGS/H) reactor, the WGS/H reactor comprising a WGS/H catalyst;
converting within the WGS/H reactor at least a portion of the carbon monoxide and at least a portion of the water to carbon dioxide and hydrogen; and
converting within the WGS/H reactor at least a portion of the oxygenate and at least a portion of the hydrogen to an alcohol and producing an alcohol outlet stream comprising at least a substantial portion of the alcohol.
