Abstract: Disclosed herein is a method for converting ethanol to 1,3-butadiene, wherein the method utilizes H2 produced during a first step of the method for subsequent conversions involved in the method. In particular aspects, H2 produced from converting ethanol to acetaldehyde is used to promote the conversion of the acetaldehyde to 1,3-butadiene. The H2 promotes enhanced catalyst stability, as well as enhanced selectivity and yields of the 1,3-butadiene product. In particular aspects, the method comprises two steps to produce the 1,3-butadiene from the ethanol and H2 produced from a first step facilitates enhanced selectivities and yields for the second step.
