Processes, systems, and catalysts for the conversion of 2-butene to 1,3-butaidene without the use of steam or, in some embodiments, with a reduced use of steam as compared to prior art processes are provided. The catalyst includes tungsten trioxide (WO) on an inorganic support includes activated magnesium oxide (MgO) and may be referred to as a 'dual catalyst' or a 'co-catalyst.' Embodiments of the catalyst. A process for the production of 1,3-butadiene may include contacting a feed stream of 2-butene with a WO-inorganic support catalyst or a MgO and WO-inorganic support catalyst and may be performed without steam in the feed stream.
