Embodiments of methods of synthesizing a metathesis catalyst system, which include impregnating tungsten oxide on silica support in the presence of a precursor to produce a base catalyst; calcining the base catalyst; dispersing a solid metal-based co-catalyst onto the surface of the base catalyst to produce a doped catalyst; and calcining the doped catalyst to produce a metathesis catalyst system. Further embodiments of processes for the production of propylene, which include contacting a hydrocarbon feedstock comprising a mixture of 1-butene and 2-butene with embodiments of the metathesis catalyst system to produce, via metathesis conversion, a product stream comprising propylene. 本发明提供合成复分解催化剂系统的方法的实施例，其包括在前体存在下将氧化钨浸渍在二氧化硅载体上以产生碱催化剂；煅烧所述碱催化剂；将基于金属的固体助催化剂分散到所述碱催化剂的表面上以产生掺杂的催化剂；且煅烧所述掺杂的催化剂以产生复分解催化剂系统。用于产生丙烯的方法的其它实施例，其包括使包含1-丁烯和2-丁烯的混合物的烃原料与所述复分解催化剂系统的实施例接触，以通过复分解转化产生包含丙烯的产物流。
